Legacy (BIOS/MBR) 方法

   Note

如果你正在使用BIOS來啟動且你System Rescue CD的開機選單是淺藍色的,使用這個方法。如果你想要使用UEFT/GPT硬碟格式,請前往下一頁

首先,你需要找到正確的硬碟來進行分割,使用這個指令來確認/dev/sda是你要用來分割的硬碟。

root # fdisk -l /dev/sda

Disk /dev/sda: 640.1 GB, 640135028736 bytes, 1250263728 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: gpt

<div class="mw-translate-fuzzy">
root #         Start          End    Size  Type            Name
 1         2048   1250263694  596.2G  Linux filesyste Linux filesystem

現在,建議你清除所有現存的MBR或GPT分割表,他會影響BIOS在開機時的工作,我們使用sgdisk來達成目的ː

   Warning

這會使任何現存的分割區消失!!!!!! "強烈" 警告與建議 你在執行之前先行備份

root # sgdisk --zap-all /dev/sda

Creating new GPT entries.
GPT data structures destroyed! You may now partition the disk using fdisk or
other utilities.

這個輸出也是非常正常的,不需要擔心,指令已正常運作ː

***************************************************************
Found invalid GPT and valid MBR; converting MBR to GPT format
in memory. 
***************************************************************

接著使用fdisk來創建MBR分割表和分割區:

root # fdisk /dev/sda

fdisk中依照下列指示操作:

清空分割表:

Command (m for help): o ↵

建立分割區1: (boot)

Command (m for help): n ↵
Partition type (default p): 
Partition number (1-4, default 1): 
First sector: 
Last sector: +128M ↵

建立分割區2 (swap):

Command (m for help): n ↵
Partition type (default p): 
Partition number (2-4, default 2): 
First sector: 
Last sector: +2G ↵
Command (m for help): t ↵ 
Partition number (1,2, default 2): 
Hex code (type L to list all codes): 82 ↵

建立root分割區:

Command (m for help): n ↵
Partition type (default p): 
Partition number (3,4, default 3): 
First sector: 
Last sector: 

驗證分割表:

Command (m for help): p

Disk /dev/sda: 298.1 GiB, 320072933376 bytes, 625142448 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x82abc9a6

Device    Boot     Start       End    Blocks  Id System
/dev/sda1           2048    264191    131072  83 Linux
/dev/sda2         264192   4458495   2097152  82 Linux swap / Solaris
/dev/sda3        4458496 625142447 310341976  83 Linux

將分割表寫入硬碟:

Command (m for help): w

全新的MBR分割表將會被寫入你的系統硬碟中。

   Note

你已經完成了硬碟分割了! 現在轉跳到建立檔案系統
