THIS WILL ERASE DATA on Disk!!!

----------------------------------------------------------------------------------------------------------
NOTE: Im using fdisk utility to partition the disk.

1. Open Your terminal and type

fdisk -l

----------------------------------------------------------------------------------------------------------

2. Now you see the list of storage devices on your system.

Select the device as below command.

fdisk /dev/sdX

Note X here represents the disk alphabet. X may be sda/sdb/nvmep01/etc...

NOTE: https://wiki.archlinux.org/index.php/Installation_guide#Partition_the_disks refer this for partition table schema.

----------------------------------------------------------------------------------------------------------

3. Now Follow below steps.

EFI partition

• d -> hit d and select partition number until all the partitions are deleted
  

• g -> creates new gpt label for disk.
  

• n -> new partition
  

• hit from 2048---end -> starting sector.
  

• when fdisk asks for +/-/ end type
  

• +512M -> EFI partition size of 512MB (At least 260 MiB )
  

• hit yes for removing signature of existing partitons.
  

• t -> to change the type of the partition
  

• -> select partition number 1,2,3 etc.
  

• L to list types -> and press Q to quit the list and select 1 on the prompt for - EFI
  

----------------------------------------------------------------------------------------------------------

SWAP partition.

• n - > new partition.
  

• Hit enter for starting sector
  

• when fdisk asks for +/-/ end type
  

• +your RAM-size + 1G -> for Hibernate Support
  

• example: if your ram size is 8GB then +9GB
  

• +4G or +8G -> Common swap partition. (Without Hibernate support).
  

• hit yes for removing signature of existing partitons.
  

• t -> to change the type of the partition
  

• -> select partition number 1,2,3 etc. (2 in this case)
  

• L to list types -> and press Q to quit the list and select 19 on the prompt for - EFI
  

----------------------------------------------------------------------------------------------------------

Root partition

• n - > new partition.
  
• Hit enter for starting sector
  
• when fdisk asks for +/-/ end hit enter this is the last partition and end of disk.
  
• This is the root partitions so it must be in Linux File System type.
  
• t -> to change the type of the partition
  
• -> select partition number 1,2,3 etc.
  
• L to list types -> select 20 - Linux File System.
  
• now write the partitions
  
• w -> this will write partition
