My laptop is (maybe was) Linux and Windows 10 dual booted. I was reinstalling the Linux OS and in the process I accidentally formatted the Windows 10 boot partition. At least I think it is the boot partition because I don’t really know how Windows works (or doesn’t work amirite).

This is the lsblk output:

$ lsblk -f
NAME        FSTYPE     FSVER LABEL [...] MOUNTPOINTS
nvme1n1     zfs_member 5000  zroot [...]
├─nvme1n1p1 vfat       FAT32       [...] /boot/efi
├─nvme1n1p2 swap       1           [...] [SWAP]
└─nvme1n1p3 zfs_member 5000  zroot [...]
nvme0n1
├─nvme0n1p1
└─nvme0n1p2 ntfs

The nvme0n1p1 is the one related to booting. I accidentally formatted it.

I have a Windows 10 USB prepared. I tried looking online and I never found a question asking exactly for this. The ones I found that were similar enough suggested different commands.

Anyone has experience with this?

Thanks in advance.

    Os prober isn’t detecting windows. I suspect it’s because the windows boot partition is gone but I’m not sure how it detects windows exactly.

      in some distros os-prober may be disabled by default (because of security reasons iirc, I don’t know why it would be unsecure) or you may need to mount the windows partition begore running os-prober

      for example in arch os-prober only checks mounted partitions

      you can try mounting your windows partition to /mnt or somewhere else where you have an empty folder before running os-prober
