I just recently installed Kubuntu onto an NVMe SSD, and now GRUB does not show my Windows 10 partition so I can't boot into Windows anymore, which is on a separate SSD. It does not appear in my system BIOS either. I've tried boot-repair but that doesn't seem to work (it says something about activating the separate boot/efi partition, which it never explains). It is not seen by os-prober and wasn't fixed by creating the "free space" partition with the GRUB flag as suggested by boot-repair. I think I accidentally deleted some file or partition or something on the NVMe SSD? I have a Windows live installer if that helps to fix it. Otherwise, the drive is still seen when I boot into Ubuntu and I can still see all the files inside.
