[SOLVED] Formatted boot partition by mistake, unable to boot system

I formatted my boot partition by mistake, which deleted my grub as well. I have tried multiple solutions after that but still facing some issues in getting the system to start:

My partitions:

1. fdisk -l
   

2. df -h
   

What i have tried:

1. Booted arch through live usb

2. Mounted my original arch system and installed grub and linux

   mkdir /mnt/arch
   mount -t auto /dev/sdb5 /mnt/arch
   arch-chroot /mnt/arch
   mount -t auto /dev/sdb3 /boot
   pacman -S grub
   pacman -S linux
   pacman -Syu
   grub-install --efi-directory=/boot --target=x86_64-efi /dev/sdb
   grub-mkconfig > /boot/grub/grub.cfg

3. Rebooted and got this error (current status)
   

I had also tried this solution https://bbs.archlinux.org/viewforum.php?id=269588. I got this:

This and most of the other which I found were solving for mismatch of kernel and boot versions. Some useful outputs:

• uname -r

  5.17.1-arch1-1

• pacman -Q linux

  linux 5.17.1-arch1-1

• cat /etc/fstab
  

If you notice the output df -h, there i no boot partition. I think issue might be related to that. Let me know if any other outputs/logs are required.
Any help is appreciated and sorry for all the images and no text. Thanks.

Re: [SOLVED] Formatted boot partition by mistake, unable to boot system

I did lsblk -f and realized my boot partition's UUID was different from the entry in /etc/fstab, got the hint from here: https://bbs.archlinux.org/viewforum.php?id=233935,

I manually changed the entry and its working now. Although my problem is solved, I just want to know if could've solved this without a manual fix? Like regenerating fstab file or some sync command for actual partitions and fstab.

Thanks.

You could've reran genfstab from arch-install-scripts like during the installation with the new partition mounted.

Please mark as [SOLVED] by editing the title in the first post, might have to shorten it a little
