Hello! Looks like I need some assistance with Windows 10 dual-boot.
I had Windows 10 dual-boot (2 SSD disks - one for Linux, one for Windows), then I updated BIOS from Windows and somehow after that Windows became only option to boot (I tried chroot and reinstall grub, but I had no success).
I actually had plans to reinstall Linux, so I did it.
After reinstalling Linux I can’t see Windows boot option in Grub.
lsblk:

nvme0n1p2 and nvme0n1p3 are Windows partitions.
Here is my fdisk -l:

os-prober now can’t find Windows option to boot in. I wonder - how could I nuke Windows EFI partition, it was on another disk?

Any ideas how to get Windows grub entry back?
Cause it’ll be pretty hard time for me to reinstall Windows 10…
