Question

grub rescue error

I forcefully deleted my ubuntu partition and on rebooting it displays unknown filesystem.

Answer 1

step1 > create a bootable USB of your Linux distribution which you forcefully deleted In my case ubuntu 16.04.

Step2 > reinstall that distribution,and if yo want to uninstall it do it with proper steps.

(if your PC does not detect the bootable USB then do as follow)

step3 > GO to your PC's BIOS and go to boot setting.

step4 > Change the boot priority of your USB to 1 by clicking on "+"or"-".

step5> restart your PC and install your OS, after installing restart your PC and again change your boot priority to hard disk. this will solve your problem.

(Note:- you don't need to upgrade your GRUB ans it will be done automatically while installing your OS.)
