# ls /sys/firmware/efi/efivars ( to check boot mode)
lsblk for listing the drives 

hdparm -i /dev/sda /b/c/d : to find the hardware info of the drive

gdisk /dev/sd*  to clean the drive and do hardware level stuff

x for expert mode
z flag to clean the whole drive

(for new users)
cfdisk /dev/sd*
gpt or mdr

boot : bios boot(for bios boot) and grub needs to be used
or
boot: efi (for uefi) and systemd boot or grub can be used
 swap:
root:
home:

grub has more features:
https://wiki.archlinux.org/title/Arch_boot_process#Boot_loader
(for advanced users)
cgdisk /dev/sd*

new

create boot(1024MiB , root,home and swap( same as ram for hybernate option else something less)
GiB
boot code:EF00
swap space:8200(code) 
root: min 20GiB 8300
home: all remaining space

write
quit
check using lsblk

formating to respective types
boot: mkfs.fat -F32 /dev/sd*1
swap: mkswap /dev/sd*2
swapon /dev/sd*2
root: mkfs.ext4 /dev/sd*3
home:mkfs.ext4 /dev/sd*4

mount the folders
mount the root drive first:
mount /dev/sd*3 /mnt

make dirs inside root for 
mounting  the boot and home

mkdir /mnt/boot
mkdir /mnt/home

mount /dev/sd*1 /mnt/boot (dont mount for grub)
mount /dev/sd*4 /mnt/home

get mirrors sorted


rank them and use best
backup the mirrorlist
cp /etc/pacman.d/mirrorlist /etc/pacman.d/mirrorlist.backup

for internet 
ip link
rfkill : https://wiki.archlinux.org/title/Network_configuration/Wireless#Rfkill_caveat
rfkill list
rfkill unblock all
