=== Types of Edits ===
|CatPkg=sys-boot/boot-update
 
|Maintainer=Drobbins
Before we get started, let's review what changes are okay to make, and what changes are not okay:
|Repository=Funtoo Overlay
 
|Organization=Funtoo Technologies
{{TableStart}}
|Overlay=Funtoo
<tr class="active"><th>Type of Change</th><th>Okay?</th></tr>
<tr><td>Grammar/spelling fixes</td><td>Yes</td></tr>
<tr><td>New wiki content</td><td>Yes</td></tr>
<tr><td>New package information</td><td>Yes</td></tr>
<tr><td>Adding to existing article</td><td>Maybe -- see below</td></tr>
<tr><td>Adding missing/incomplete information</td><td>Yes</td></tr>
<tr><td>Making corrections</td><td>Yes</td></tr>
<tr class="danger"><td>Adding work-arounds to problems experienced</td><td>No - open bug first on [http://bugs.funtoo.org bug tracker].</td></tr>
{{TableEnd}}
 
{{important|Note that if you experience some problem with Funtoo Linux, during installation or otherwise, the proper course of action is to not add a work-around to our documentation, but to ''open a bug on our bug tracker.'' This is important because the problem you experienced may be a legitimate bug and the solution may be to fix the bug rather than add a work-around to our documentation. We may end up fixing a bug, making a documentation fix, or possibly both.}}
 
=== Basics ===
 
Here is a list of basic wiki information that you will need to know to get started:
 
* First, to perform edits on the wiki, you must {{CreateAccount}} and log in.
* You can create a new page by navigating to http://www.funtoo.org/New_Page_Name. Underscores are the equivalent of spaces. Then select "Create" under the "Actions" menu.
* Whether creating a new page or editing an existing page by clicking "Edit", you will be presented with Web-based text editor that allows you to modify the ''wikitext'' of the page. The wikitext is rendered to produce the document you see when you view the page normally.
* Another fun thing you can do is click on your name under the "Account" menu once you have logged in. This will bring you to your "User" page. Then click "Create with Form" unde the "Actions" menu and enter your geographic and other information. This will allow you to be displayed on our [[Usermap]] and will also allow your full name to be displayed on [[:Category:Ebuilds|Ebuild pages]] for which you are an author. It's generally a good idea to do this.
 
{{tip|The following sections document how to use wikitext and Funtoo templates on the Funtoo wiki.}}
 
=== Paragraphs ===
 
To create a new paragraph, insert a blank line between two lines of text. If a blank line doesn't exist between two lines of wikitext, they will be combined into a single flowing paragraph.
 
If you leave leading whitespace at the beginning of a line, MediaWiki will render it as pre-formatted text. Beware of this. Here's an example:
 
foobar
 
This can rear its ugly head when specifying template parameters, so you will get this:
 
{{note| ugh!}}
 
...instead of this:
 
{{note|This looks much better!}}
 
=== Page and Section Capitalization ===
 
In general, capitalize all words in page names and section heading except:
* Articles: a, an, the
* Coordinating Conjunctions: and, but, or, for, nor, etc.
* Prepositions (fewer than five letters): on, at, to, from, by, etc.
 
=== Document Hierarchy ===
 
Use section headings to create a document hierarchy for your page. These will define the table of contents that appears at the top of the wiki page. Create chapters, sections and sub-sections as follows:
 
<pre>= Page Title =
 
== Chapter Title ==
 
=== Section Title ===
 
==== SubSection Title ====
 
</pre>
 
{{Note|By default, Table of Contents is disabled on the Funtoo wiki. If you would like to enable the TOC, you can place a <code><nowiki>__TOC__</nowiki></code> on a blank line where you'd like the Table of Contents to appear, or place <code><nowiki>__FORCETOC__</nowiki></code> on a blank line anywhere in the wikitext to force the TOC to appear at the top of the page.}}
 
In general, when creating new documents, it's best to use level-3 (three "="'s) Section Titles to break up content. Level-2 Section Titles are best used for major sections of larger documents. Use them infrequently. Level-1 Section Titles generally do not need to be used.
 
=== Links ===
 
Internal links to other wiki pages can be specified as <tt><nowiki>[[pagename]]</nowiki></tt>. To specify an alternate name for the link, use <tt><nowiki>[[pagename|my link name]]</nowiki></tt>.
 
For external links, use <tt><nowiki>[http://funtoo.org my link]</nowiki></tt> to specify a URL. If you want the URL to appear in the wikitext, you can specify it without brackets: http://forums.funtoo.org.
 
=== Lists ===
 
MediaWiki supports a number of list formats:
 
* Unordered List
* Unordered Item 2
** Unordered sub-item
 
# Ordered List
# Ordered Item 2
## Ordered sub-item
 
;Term: This is called a "definition list". It is used when defining various terms.
 
If you need to quote a portion of text from another site, use <tt><nowiki><blockquote></nowiki></tt> as follows:
 
<blockquote>
Wikipedia (ˌwɪkɨˈpiːdiə/ or wɪkiˈpiːdiə/ wik-i-pee-dee-ə) is a collaboratively edited, multilingual, free-access, free content Internet encyclopedia that is supported and hosted by the non-profit Wikimedia Foundation. Volunteers worldwide collaboratively write Wikipedia's 30 million articles in 287 languages, including over 4.5 million in the English Wikipedia. Anyone who can access the site can edit almost any of its articles, which on the Internet comprise[4] the largest and most popular general reference work.[5][6][7][8][9] In February 2014, The New York Times reported that Wikipedia is ranked fifth globally among all websites stating, "With 18 billion page views and nearly 500 million unique visitors a month..., Wikipedia trails just Yahoo, Facebook, Microsoft and Google, the largest with 1.2 billion unique visitors."[10]
</blockquote>
 
=== Literal Text and HTML Symbols ===
 
Here is wikitext for the section above, which I am displaying by placing the literal wikitext between a &#60;pre&#62; and &#60;/pre&#62; tag. If you want to disable wikitext processing for an inline span of text, use &#60;nowiki&#62; and &#60;/nowiki&#62;. If you want to print out a tag literally, use &amp;#60; and &amp;#62; (In the wikitext, I used &amp;amp;#60; and &amp;amp;#62 to display these!)
 
<pre>
* Unordered List
* Unordered Item 2
** Unordered sub-item
 
# Ordered List
# Ordered Item 2
## Ordered sub-item
 
;Term: This is called a "definition list". It is used when defining various terms.
 
If you need to quote a portion of text from another site, use <tt><nowiki><blockquote></nowiki></tt> as follows:
 
<blockquote>
Wikipedia (ˌwɪkɨˈpiːdiə/ or wɪkiˈpiːdiə/ wik-i-pee-dee-ə) is a collaboratively edited, multilingual, free-access,
free content Internet encyclopedia that is supported and hosted by the non-profit Wikimedia Foundation. Volunteers
worldwide collaboratively write Wikipedia's 30 million articles in 287 languages, including over 4.5 million in the
English Wikipedia. Anyone who can access the site can edit almost any of its articles, which on the Internet
comprise[4] the largest and most popular general reference work.[5][6][7][8][9] In February 2014, The New York
Times reported that Wikipedia is ranked fifth globally among all websites stating, "With 18 billion page views
and nearly 500 million unique visitors a month..., Wikipedia trails just Yahoo, Facebook, Microsoft and Google,
the largest with 1.2 billion unique visitors."[10]
</blockquote>
</pre>
 
=== Linking to Packages ===
 
To link to a package page, use the <code>Package</code> template:
 
<pre><nowiki>
{{Package|sys-apps/portage}}
</nowiki></pre>
 
This template will create a link to the official wiki page for sys-apps/portage, and render using the official "English" page name, as follows:
 
{{Package|sys-apps/portage}}
 
If you specify a yet-to-be-documented ebuild, it will render like this (which is okay -- it will encourage people to document it):
 
{{Package|sys-foo/undocumented-ebuild}}
 
=== Tables ===
 
Instead of using traditional MediaWiki table wikitext, use the following format:
 
<pre>
{{TableStart}}
<tr class="info"><th>Header 1</th><th>Header 2</th></tr>
<tr><td>Value 1</td><td>Value 2</td></tr>
<tr><td>Value 3</td><td>Value 4</td></tr>
{{TableEnd}}
</pre>
 
This wil render as follows:
 
{{TableStart}}
<tr class="info"><th>Header 1</th><th>Header 2</th></tr>
<tr><td>Value 1</td><td>Value 2</td></tr>
<tr><td>Value 3</td><td>Value 4</td></tr>
{{TableEnd}}
 
{{tip|This table syntax has an added benefit of creating a responsive table that renders properly on mobile devices.}}
 
It is possible to use the following CSS classes with <code>tr</code> (rows) and <code>td/th</code> elements to color them as desired:
 
{{TableStart}}
<tr class="active"><td>Class Name</td></tr>
<tr class="success"><td>success</td></tr>
<tr class="info"><td>info</td></tr>
<tr class="warning"><td>warning</td></tr>
<tr class="active"><td>active</td></tr>
<tr class="danger"><td>danger</td></tr>
{{TableEnd}}
 
=== Displaying Source Code ===
 
To display source code, use the <tt>&#60;syntaxhighlight&#62;</tt> tag, which has the ability to perform syntax highlighting on the source code for easier reading:
<pre>
<syntaxhighlight lang="python">
import system
</syntaxhighlight>
</pre>
 
This will produce the following output:
 
<syntaxhighlight lang="python">
import system
</syntaxhighlight>
 
Alternatively, if you need a caption, use can use the file template, specifying a <tt>lang=</tt> parameter:
 
<pre>
{{file|name=foobar|lang=python|desc=foobarosity|body=
import system
}}
}}
</pre>
Funtoo boot-update provides a unified mechanism for configuring the GRUB 1.9x ({{Package|sys-boot/grub}}) and GRUB 0.97 ({{Package|sys-boot/grub-legacy}}) boot loaders. It is the recommended, official way to configure Funtoo Linux systems for booting.
 
This will produce:


{{file|name=foobar|lang=python|desc=foobarosity|body=
== Current Version ==
import system
}}


{{important|If you need to display the pipe ("{{!}}") character within the body of a file template, replace each "{{!}}" with <nowiki>{{!}}</nowiki> -- otherwise your file contents will not display properly. This is necessary because <nowiki>{{file}}</nowiki> is a template and the "{{!}}" character is used as a delimiter for arguments to the template.}}
* {{Package|sys-boot/boot-update}}


Note that the language should be specified in the <tt>lang</tt> attribute. For a list of supported languages, see [http://www.mediawiki.org/wiki/Extension:SyntaxHighlight_GeSHi#Supported_languages this list].
== Man Pages ==
Consult the following man pages for detailed, up-to-date information on configuration file settings and command-line arguments:


=== Displaying Text File Contents ===
* boot-update(8)
* boot.conf(5)


For displaying the contents of non-programming language text files (like config files), you have two options. You can enclose your lines within <tt>&#60;pre&#62;</tt> tags, or use the new [[Template:File|file template]]. The file template is used like so:
{{:Install/BootLoader}}


<pre>
=== GRUB 0.97 (grub-legacy) Quick Start ===
{{file|name=/etc/foo.conf|desc=My foo.conf file|body=
# /etc/host.conf:
# $Header: /var/cvsroot/gentoo/src/patchsets/glibc/extra/etc/host.conf,v 1.1 2006/09/29
}}
</pre>


This will produce:
If using <code>sys-boot/grub-legacy-0.97</code>, perform the following steps:


{{file|name=/etc/foo.conf|desc=My foo.conf file|body=
* Partition disk using MBR partitions '''(GPT not supported)'''
# /etc/host.conf:
* Install kernel/initrd to <code>/boot</code>
# $Header: /var/cvsroot/gentoo/src/patchsets/glibc/extra/etc/host.conf,v 1.1 2006/09/29
}}


=== Console ===
To display console output, use the <tt>&#60;console&#62;</tt> tag:
For a root console:
<pre>
<console>
<console>
###i## run a command as root
###i## emerge sys-boot/boot-update
###i## emerge ">=sys-boot/grub-legacy-0.97-r11"
###i## grub-install-legacy /dev/sda
</console>
</console>
</pre>
Due to an issue with <code>grub-legacy</code>, you may see the following message:
Produces:
<console>
<console>
###i## run a command as root
###i## grub-install-legacy /dev/sda
The file /boot/grub-legacy/stage1 not read correctly.
</console>
</console>
 
Should you receive this message, you will have to install <code>grub-legacy</code> from the grub shell.
For a non-root console:
Assuming <code>/boot</code> is the partition <code>/dev/sda1</code> and you want to install grub to the MBR, you would run the following:
<pre>
<console>
<console>
$ ##i##run a command as user
###i## grub-legacy
root (hd0,0)
setup (hd0)
quit
</console>
</console>
</pre>
When adjusting to fit your setup, remember 'root' is the location of your boot partition, 'setup' is where you want to install grub, and don't forget about grub's unique naming conventions for hard drives / partitions. For more information run:
Produces:
<console>
<console>
$ ##i##run a command as user
###i## info grub-legacy
</console>
</console>


{{important|1=
Ensure that <code>/etc/fstab</code> is correct, and edit <code>/etc/boot.conf</code> to reflect your installation.
Note that we use a <tt>#</tt> prompt for <tt>root</tt> and a <tt>$</tt> prompt to denote a non-root user.}}
Ensure a <code>generate grub-legacy</code> setting in the <code>boot</code> section. Then run:


{{important|The <tt>##i##</tt> text tags the rest of the line as being ''user input'' ("i" is for "input"). It is then highlighted in a noticeable color so it stands out from text that is not typed in by the user.}}
<console>
 
###i## boot-update
If you need to end highlighting of user input prior to the end of a line, use <code>##!i##</code> to mark the end of the highlighted area.
 
The following special character sequences are also available:
* <code>##g##</code> - Green
* <code>##y##</code> - Yellow
* <code>##bl##</code> - Blue
* <code>##r##</code> - Red
* <code>##b##</code> - Bold
 
Please use the above coloring options sparingly. It is sometimes nice to use them to get wiki console output to match the colors that are displayed on a Linux console. Also note that for every color above, there is a matching <code>##!(colorcode)##</code> option to turn color off prior to end of line.
 
Here is an example of its use:<console>
# ##i##bluetoothctl
[##g##NEW##!g##] Controller 00:02:72:C9:62:65 antec [default]
##bl##[bluetooth]##!bl###power on
Changing power on succeeded
##bl##[bluetooth]##!bl### ##i##agent on
Agent registered
##bl##[bluetooth]##!bl### ##i##scan on
Discovery started
##bl##[bluetooth]##!bl### ##i##devices
Device 00:1F:20:3D:1E:75 Logitech K760
##bl##[bluetooth]##!bl### ##i##pair 00:1F:20:3D:1E:75
Attempting to pair with 00:1F:20:3D:1E:75
[##y##CHG##!y##] Device 00:1F:20:3D:1E:75 Connected: yes
##r##[agent]##!r## Passkey: 454358
##r##[agent]##!r## Passkey: ##i##4##!i##54358
##r##[agent]##!r## Passkey: ##i##45##!i##4358
##r##[agent]##!r## Passkey: ##i##454##!i##358
##r##[agent]##!r## Passkey: ##i##4543##!i##58
##r##[agent]##!r## Passkey: ##i##45435##!i##8
##r##[agent]##!r## Passkey: ##i##454358##!i##
[##y##CHG##!y##] Device 00:1F:20:3D:1E:75 Paired: yes
Pairing successful
[##y##CHG##!y##] Device 00:1F:20:3D:1E:75 Connected: no
##bl##[bluetooth]##!bl### ##i##connect 00:1F:20:3D:1E:75
Attempting to connect to 00:1F:20:3D:1E:75
[##y##CHG##!y##] Device 00:1F:20:3D:1E:75 Connected: yes
Connection successful
##bl##[bluetooth]##!bl### ##i##quit
[##r##DEL##!r##] Controller 00:02:72:C9:62:65 antec [default]
#
</console>
</console>
This will auto-generate the <code>/boot/grub-legacy/grub.conf</code> required for booting. Note that <code>grub-legacy-0.97-r11</code> and later stores <code>grub.conf</code> in the <code>/boot/grub-legacy</code> directory.


=== Informational Messages ===
Re-run <code>boot-update</code> every time your available kernels / initrds or <code>/etc/boot.conf</code> configuration changes.
Notes, warnings, tips, and important templates can be used for informational messages that need to be offset from the regular text flow:
 
<pre>{{note|this is a note}}</pre>
{{note|this is a note}}
 
<pre>{{important|this is important}}</pre>
{{important|this is important}}
 
<pre>{{warning|this is a warning}}</pre>
{{warning|this is a warning}}
 
<pre>{{tip|this is a tip}}</pre>
{{tip|this is a tip}}
 
Note that these templates used to be called <code>fancynote</code>, <code>fancytip</code>, etc. The "fancy" names have been deprecated but will still be supported for the forseeable future.
 
=== Kernelop ===
To display kernel configuration options, we encourage you to use the <tt>kernelop</tt> template. To use the <tt>kernelop</tt> template, create an entry similar to the following example:
<pre>
{{kernelop|title=foo,bar|desc=
kernel options pasted from "make menuconfig"
}}
</pre>
 
{{note|Kernelop is colored blue to slightly resemble the blueish background from <tt>make menuconfig</tt>.}}
 
Adding this entry will give you the following output:
{{kernelop|title=foo,bar|desc=
kernel options
}}
 
Here's a more concrete example:
{{kernelop|title=File systems|desc=
<M> Second extended fs support         
[ ]  Ext2 extended attributes         
[ ]  Ext2 execute in place support   
<M> Ext3 journalling file system support
}}
 
Examples of usage:
* [[Package:AMD Catalyst Video Drivers]]
* [[Package:ACPI Daemon]]
* [[Microcode]]
 
=== Discussion Pages ===
 
In MediaWiki, every "regular" wiki page has a corresponding "Talk" or "Discussion" page which has a page name prefixed by "Talk:" -- you can get to this page by going to the "Action" menu, and then choosing the "Discussion" menu item. These talk pages are typically used to discuss the edits that are going on in the "main" wiki page. The problem with talk pages is that they are kind of a pain to use. However, we have a way to fix that. If you want to enable a DISQUS-based mini-forum on a talk page, insert the following wikitext on the Talk page:
 
<pre>
{{DISQUS}}
</pre>
 
...and presto! You will now have DISQUS-powered mini-forums to discuss whatever you want about your wiki page.
 
== Marking Pages as Needing Updates ==
 
If you find outdated wiki content, but you don't have the time or ability to update it, add one of the following templates to the wikitext of the page. This will add the page to the [[:Category:Needs Updates|Needs Updates Category]] so we can identify pages that need updating:
 
<pre>
{{PageNeedsUpdates}}
{{SectionNeedsUpdates}}
</pre>
 
 
Examples of usage:
* [[UEFI Install Guide]]
* [[Package:MediaWiki]]
* [[Clang]]
 
=== Inline Code ===
 
To emphasize commands, and other technical jargon when they appear inline in a paragraph, use the <nowiki>{{c}}</nowiki> template. When referencing files, use the <nowiki>{{f}}</nowiki> template.
 
<pre>
The {{f|/etc/fstab}} file is an important one. Another important file is {{f|/boot/grub/grub.cfg}}. The {{c|emerge}} command is really nifty.
</pre>
 
This example produces the following output:
 
The {{f|/etc/fstab}} file is an important one. Another important file is {{f|/boot/grub/grub.cfg}}. The {{c|emerge}} command is really nifty.
 
{{important|1=
The &#60;tt&#62; tag has been deprecated for the purpose of tagging inline code, to conform with HTML5, and the previous use of the &#60;code&#62; tag is discouraged. It is more maintainable to use the <nowiki>{{c}}</nowiki> template. }}
 
=== Slideshow ===
 
Any page has the capability of displaying a slideshow. Adding a slideshow to a page involves three steps:
 
# Upload Images
# Define Slides
# Add Slideshow to page
 
==== Upload Images ====
 
To upload images, head to [[Special:Upload]] and upload a file. It is highly recommended to upload JPEG format images in high resolution -- MediaWiki will handle scaling JPEG automatically, saving bandwidth, but does not do this for PNG. Make sure that all images you upload have the same dimensions. When you upload, make note of the '''Destination Filename''' field -- this is the name that the upload will use when you reference it in your slide. It is recommended that you choose a simple descriptive name ending in ".jpg" for the '''Destination Filename'''.
 
==== Define Slides ====
 
Once images have been uploaded, you must define slides. To define slides on a page, you enter special semantic information about the slide on the page that it will be displayed, in the following format:
 
<pre><nowiki>
{{#subobject:|slideIndex=0|slideCaption=
== Wikitext Here ==
This is a fantastic slide!
|slideImage=File:Fruit.jpg|slideLink=PageName}}
</nowiki></pre>
 
Here are some important instructions regarding defining slides:
 
* <code>slideIndex</code> must be 0 for the first slide, 1 for the second slide, etc. Numbers must be unique and incrementing from zero, and not doing this will result in slideshow display errors (but can be easily fixed by correcting the wikitext.)
* <code>slideCaption=</code> can contain wikitext, such as headings and links. The best way to enter <code>slideCaption</code> is as above -- type a literal <code>slideCaption=</code>, followed by enter, then specify your wikitext, and terminate the caption by a single pipe character on the following line. Pipe characters are used to separate arguments from each other.
* Specify your image name in the <code>slideImage</code> field. Your slideImage will have a name of <code>File:myname.jpg</code>, where <code>myname.jpg</code> is the '''Destination Filename''' you used when uploading the image.
* An optional parameter called <code>slideLink=</code> can be provided to allow the image to be clickable and link to another wiki page. If it is omitted, then the image will not be clickable.
 
==== Add Slideshow to Page ====
 
Once the slides have been added to the page, you can add the following text to your page at the point you'd like the slideshow to appear:
<pre>
{{Slideshow}}
</pre>
 
=== YouTube Videos (Screencasts, etc.) ===
 
Screencasting is an easy method to explain complex tasks. Take for instance <code>youtu.be/5KDei5mBfSg</code> and chop off the id and insert it into the following syntax to produce a video example.
 
<pre>{{#widget:YouTube16x9|id=5KDei5mBfSg}}</pre>
{{#widget:YouTube16x9|id=5KDei5mBfSg}}
 
{{tip|The sample video above explains how to create your own screencasts under Funtoo Linux.}}
 
Most YouTube videos are in 16x9 format and should use the <code>YouTube16x9</code> widget. There is also a <code>YouTube4x3</code> widget for videos with a 4x3 aspect ratio.
{{note|These YouTube widgets have been updated to be mobile-friendly.}}

Boot-Update

   Tip

We welcome improvements to this page. To edit this page, Create a Funtoo account. Then log in and then click here to edit this page. See our editing guidelines to becoming a wiki-editing pro.

Funtoo boot-update provides a unified mechanism for configuring the GRUB 1.9x (No results) and GRUB 0.97 (No results) boot loaders. It is the recommended, official way to configure Funtoo Linux systems for booting.

Current Version

Man Pages

Consult the following man pages for detailed, up-to-date information on configuration file settings and command-line arguments:

  • boot-update(8)
  • boot.conf(5)

Installing a Bootloader

These install instructions show you how to use GRUB to boot using BIOS (old-school) or UEFI (new-school). As of boot-update-1.7.2, now in Portage, the steps are very similar.

First, emerge boot-update. This will also cause grub-2 and efibootmgr to be merged, since they are dependencies:

(chroot) # emerge boot-update

Then, edit /etc/boot.conf using nano and specify "Funtoo Linux genkernel" as the default setting at the top of the file, replacing "Funtoo Linux".

/etc/boot.conf should now look like this:

   /etc/boot.conf
boot {
	generate grub
	default "Funtoo Linux genkernel" 
	timeout 3 
}

"Funtoo Linux" {
	kernel bzImage[-v]
}

"Funtoo Linux genkernel" {
	kernel kernel[-v]
	initrd initramfs[-v]
	params += real_root=auto 
} 

"Funtoo Linux better-initramfs" {
	kernel vmlinuz[-v]
	initrd /initramfs.cpio.gz
}

If you are booting a custom or non-default kernel, please read man boot.conf for information on the various options available to you.

Old School (BIOS) MBR

When using "old school" BIOS booting, run the following command to install GRUB to your MBR, and generate the /boot/grub/grub.cfg configuration file that GRUB will use for booting:

(chroot) # grub-install --target=i386-pc --no-floppy /dev/sda
(chroot) # boot-update

New School (UEFI) Boot Entry

If you're using "new school" UEFI booting, run of the following sets of commands, depending on whether you are installing a 64-bit or 32-bit system. This will add GRUB as a UEFI boot entry.

For x86-64bit systems:

(chroot) # grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id="Funtoo Linux [GRUB]" --recheck /dev/sda
(chroot) # boot-update

For x86-32bit systems:

(chroot) # grub-install --target=i386-efi --efi-directory=/boot --bootloader-id="Funtoo Linux [GRUB]" --recheck /dev/sda
(chroot) # boot-update

First Boot, and in the future...

OK -- you are ready to boot!

You only need to run grub-install when you first install Funtoo Linux, but you need to re-run boot-update every time you modify your /etc/boot.conf file or add new kernels to your system. This will regenerate /boot/grub/grub.cfg so that you will have new kernels available in your GRUB boot menu, the next time you reboot.

GRUB 0.97 (grub-legacy) Quick Start

If using sys-boot/grub-legacy-0.97, perform the following steps:

  • Partition disk using MBR partitions (GPT not supported)
  • Install kernel/initrd to /boot
root # emerge sys-boot/boot-update
root # emerge ">=sys-boot/grub-legacy-0.97-r11"
root # grub-install-legacy /dev/sda

Due to an issue with grub-legacy, you may see the following message:

root # grub-install-legacy /dev/sda
The file /boot/grub-legacy/stage1 not read correctly.

Should you receive this message, you will have to install grub-legacy from the grub shell. Assuming /boot is the partition /dev/sda1 and you want to install grub to the MBR, you would run the following:

root # grub-legacy
root (hd0,0)

When adjusting to fit your setup, remember 'root' is the location of your boot partition, 'setup' is where you want to install grub, and don't forget about grub's unique naming conventions for hard drives / partitions. For more information run:

root # info grub-legacy

Ensure that /etc/fstab is correct, and edit /etc/boot.conf to reflect your installation. Ensure a generate grub-legacy setting in the boot section. Then run:

root # boot-update

This will auto-generate the /boot/grub-legacy/grub.conf required for booting. Note that grub-legacy-0.97-r11 and later stores grub.conf in the /boot/grub-legacy directory.

Re-run boot-update every time your available kernels / initrds or /etc/boot.conf configuration changes.
