Arch linux partition using fdisk

instructions.txt

# wipefs removes all filesystem signatures from the disk, including partition tables.
# This does not overwrite the actual data but removes metadata so the disk appears unformatted.
# If you want to securely wipe the disk, use a method like dd or blkdiscard.
sudo wipefs --all /dev/nvme0n1


Using fdisk to prepare your disk for Arch Linux installation involves partitioning the disk as per your notes. Here’s a step-by-step guide:

Step 1: Start fdisk
Run fdisk on the target disk (e.g., /dev/sda):

bash
Copy code
sudo fdisk /dev/sda
Step 2: Create Partitions
Step 2.1: Create EFI System Partition (500MB)
Enter n to create a new partition.
Choose p for primary.
Enter partition number: 1.
Set First Sector (press Enter to accept the default).
Set Last Sector: +500M (for 500MB).
Mark it as EFI:
Press t to change the partition type.
Enter 1 (partition number).
Enter ef for EFI System.
Step 2.2: Create Swap Partition (8GB)
Enter n to create a new partition.
Choose p for primary.
Enter partition number: 2.
Set First Sector (press Enter to accept the default).
Set Last Sector: +8G (for 8GB).
Mark it as Linux Swap:
Press t to change the partition type.
Enter 2 (partition number).
Enter 82 for Linux Swap.
Step 2.3: Create Root Partition (Remaining Space)
Enter n to create a new partition.
Choose p for primary.
Enter partition number: 3.
Set First Sector (press Enter to accept the default).
Set Last Sector: Press Enter to use the remaining disk space.
Mark it as bootable:
Press a to toggle the bootable flag.
Enter 3 (partition number).
Step 3: Verify Partition Table
Press p to print the partition table.
It should look similar to this:
bash
Copy code
Device       Boot   Start       End   Sectors   Size Id Type
/dev/sda1    *      2048    1050623   1048576   500M ef EFI (FAT-12/16/32)
/dev/sda2          1050624  17825791  16777216   8G  82 Linux swap
/dev/sda3          17825792 <end>    <remaining size> 83 Linux
Step 4: Write Changes
Press w to write changes to the disk and exit fdisk.
