I cannot make the change, so posting here on the forum.

Configure UEFI Boot with EFISTUB

1. `sudo efibootmgr -c -d /dev/sda -p 1 -L "Obarun" -l \vmlinuz-linux -u "root=LABEL=ROOT ro resume=LABEL=SWAP quiet initrd=\intel-ucode.img initrd=\initramfs-linux.img"`
Correction is bolded in the quote.
I see that the update was made. Thank you, wikiman! :)

Here's another suggested correction. Step 1 should be to mount /dev/sda3 (root partition) to /mnt but it says /dev/sda2 which is the swap partition:

Mount the partitions to prepare for the installation:

`sudo mount /dev/sda2 /mnt`
(a) If you want to boot with EFISTUB:(see below)
`sudo mkdir /mnt/boot && mount /dev/sda1 /mnt/boot`
(b) If you want to boot with GRUB:(see below)
`sudo mkdir /mnt/efi && mount /dev/sda1 /mnt/efi`[3]
`sudo mount /dev/sda4 /mnt/home`
`sudo swapon /dev/sda2`
@ runfox, thanks fixed.
