安装指南：MBR 分区
| Install Guide, Chapter 3 | < Prev | Next > |
传统（BIOS/MBR）方法
如果使用 BIOS 启动，并且 Funtoo LiveCD 初始启动菜单是浅蓝色的，就使用这个方法。如果要使用 UEFI/GPT 磁盘格式，那么请至下一节继续。
First, it's a good idea to make sure that you've found the correct hard disk to partition. Try this command and verify that /dev/sda is the disk that you want to partition:
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 # Start End Size Type Name 1 2048 1250263694 596.2G Linux filesyste Linux filesystem
现在，建议擦除磁盘上任何现有的 MBR 或 GPT 分区表，否则可能会在启动时混淆系统的 BIOS。我们使用 sgdisk 来完成这项工作。
This will make any existing partitions inaccessible! You are strongly cautioned and advised to backup any critical data before proceeding.
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.
This output is also nothing to worry about, as the command still succeeded:
*************************************************************** Found invalid GPT and valid MBR; converting MBR to GPT format in memory. ***************************************************************
Now we will use fdisk to create the MBR partition table and partitions:
root # fdisk /dev/sda
Within fdisk, follow these steps:
清空分区表：
Command (m for help): o ↵
创建分区 1（引导）：
Command (m for help): n ↵ Partition type (default p): ↵ Partition number (1-4, default 1): ↵ First sector: ↵ Last sector: +128M ↵
创建分区 2（交换）：
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 ↵
创建根目录分区：
Command (m for help): n ↵ Partition type (default p): ↵ Partition number (3,4, default 3): ↵ First sector: ↵ Last sector: ↵
验证分区表：
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
将分区表写入磁盘：
Command (m for help): w
新的 MBR 分区表现在将被写入系统磁盘。
You're done with partitioning! Now, jump over to Creating filesystems.
