Boot livecd ISO from HDD
From Funtoo Linux
This is the approved revision of this page, as well as being the most recent.
With grub2 you can easily boot livecd image from hard drive.
[edit] General guide
This is general example. I will add settings for different livecd's later.
1. Copy the iso image to root folder for simplicity :
cp /home/user/downloads/systemrescuecd.iso /src.iso
2. Reboot and when grub2 loads press 'c' for console. Use following commands (tab autocompletion is your friend) :
loopback loop (hd0,2)/src.iso linux (loop)/boot/vmlinuz initrd (loop)/boot/initrd.lz boot
