I've been stuck on GRUB Rescue for 1 day now, I deleted the Ubuntu partition from windows7, I had Ubuntu 20.04.1 which is probably the latest version right now, I downloaded it from my USB with balena etcher. after deleting the entire Ubuntu partition I restarted my PC to see if anything would go wrong, I automatically got presented with grub rescue.
The ls command does not work, I cannot boot into Windows from my USB to fix it in the installer because GRUB rescue wont let me, I cant boot into my USB, it shows it as a hard disk, making it bootable or ISO it just doesn't work, and GRUB Rescue will not let me do any other way, what can I do?
