I had 2 OSs, Windows 10 and Ubuntu 20.04. They were working fine, but then I installed Arch Linux and it only shows Arch in grub. I think I may have deleted my bootloader.
Things that I tried, but none worked:
Using Windows 10 DVD repair tool and cmd
Rescatux 0.73
Super Grub Disk (It let me enter Ubuntu 20.04, but I'm still unable to boot into Windows 10.)
Updating grub
and then it doesn't show the grub. Instead it shows an error that says No partition active .
I don't care if I need to delete Ubuntu or Arch, but I can't reinstall Windows 10.
