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.

    Have you tried a bootrec /fixmbr?

    Iirc, when someone (definitely not me) did this, I had to do all that fixmbr stuff and then maybe(idk, was a while ago) reinstall the bootmanager I was using.
