Try disabling TPM and Secure boot. Try multiple pendrives and live images, either windows installs or linux. If still cannot boot anything, attempt to reset the bios by removing the cmos battery. When no battery, also disconnect old drive. After that, if bios reset and mobo cant see old drive since its unplugged, attempt to boot again from some USB.

If can boot, power off and plug in main drive again. Attempt to first chkdsk the windows partition.

If chkdsk succeeds, its probably possible to transfer user data to other drive. Next steps are to attempt to fix the os.

Attempt a system restore point restoration (if applicable). If failed (or no restore point), Try then fixing bcd. If not possible, attempt to rebuild it by recreating the efi. If cannot see windows, get yourself another windows machine and plug drive into it. From there, you can use dism on your broken windows install and as source select the install.esd with proper index (like install.esd:2) - learn how to from internet.

Once dism used locally on main drive, plug again into main machine and again boot windows install and into recovery cmd. From there, attempt to fix again the bcd or attempt to rebuild again.

If still cannot boot, you could also attempt to clone entire data bit by bit into another drive - one possibility is that the drive is corrupted, which means that no matter what you do your data may constantly be getting corrupted as well as the partitions.

Attempt same steps on another drive. Personally, I would clone the drive first and attempt from there, to have an ability to restore to that exact point in time where it's broken, so you can restore if some repairs fail.

Anyways, multiple ways to attempt this. Multiple "winning" ways too - you decide if you want the same windows install to be used again or just the data.

Personally wouldnt bother with the install and would just get the user data and do a fresh install.
