partition failure and system crush

[H.Yang]

Hello,

I wrongly deleted partition /windows in Windows and then Ubuntu failed :(. As I try to reinstall ubuntu with a usb disk, it show me that
'unable to install grub in /dev/sda
executing 'grub-install /dev/sda' failed.' this is a fatal error.

Appreciate for any suggestion from you.

Description: Ubuntu 22.04.3 LTS
Release: 22.04

Thank you!
