I have a laptop HP ProBook. I installed Windows 10 and over it Ubuntu 20.04. Windows partition was encrypted by BitLocker. I used both OS for a long time, and it works perfectly! I loaded the preferred OS using GRUB, and there was no problem.
Unfortunately, one week ago, I tried to load windows, and it asked me for a recovery key. I checked all my Microsoft accounts, looking for a file, and checked all USB sticks, but there are no recovery keys 🙁
What happened before: In windows, I connected an external USB HDD to my laptop, and maybe I ejected it non-safety. Also, I think it can be any update of Bios or Windows.
Due to this issue:
- I tried to load Windows directly from UEFI boot (without GRUB)
- I tried to recover the bootloader using Microsoft advanced mode
- Tried force recovery
manage-bde -forcerecovery c:non-effect
Command sudo fdisk -l shows next partitions:
Device Start End Sectors Size Type
/dev/nvme0n1p1 2048 534527 532480 260M EFI System

/dev/nvme0n1p5 725395456 998428671 273033216 130,2G Linux filesystem
Command sudo os-prober shows next result:
/dev/nvme0n1p1@/EFI/Microsoft/Boot/bootmgfw.efi:Windows Boot Manager:Windows:efi
I suspect a boot issue, but I do not know how to fix it.
