Método de la Vieja Escuela (BIOS/MBR)

   Note

Utilice este método si está iniciando con su BIOS y si el menú de inicio del "System Rescue CD" fue azul claro. Si va a utilizar el formato de disco UEFI / GPT, continúe con la siguiente sección.

Primero, es una buena idea asegurarse de haber encontrado el disco duro correcto para la partición. Pruebe este comando y verifique que / dev / sda es el disco que desea particionar:

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

root #         Start          End    Size  Type            Name
 1         2048   1250263694  596.2G  Linux filesyste Linux filesystem

Ahora, se recomienda que borre cualquier tabla de partición MBR o GPT existente en el disco, lo que podría confundir el BIOS del sistema en el momento del arranque. Lo logramos usando sgdisk:

Template:Advertencia

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:

Empty the partition table:

Command (m for help): o ↵

Create Partition 1 (boot):

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

Create Partition 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 ↵

Create the root partition:

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

Verify the partition table:

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

Write the partition table to disk:

Command (m for help): w

Your new MBR partition table will now be written to your system disk.

You're done with partitioning! Now, jump over to Creating filesystems.
