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
在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
