    Well I mean that you don't need to download the original Bios to get the bios lock from it. That was the point. They can just flash the dump and do it from there, and they won't need to look for any GUID or anything. It's much simpler the way I posted.

    BTW new AMIBCP. You may want to update that into your original file.
    This AMIBCP works on the 8th gen GT75 and GT83 bios. The 5.01 version crashes on some menus. (this can cause a corrupt bios capsule).

    As a note (It may have been already discussed): If you do perform a CMOS Reset, and you had your drives encrypted with bit locker, it will detect the hardware reset as a change in hardware, and may require the bitlocker key to unlock the drive. Make sure you have your key handy in such case!

    I had a long day with this, a couple of weeks ago.

    Maybe that happens on Windows, did not test, but with linux and dislocker you can unlock the encrypted drive on a different computer, provided you know the password (key file not needed). I've tested encrypting a pendrive with Bitlocker AES-XTS on the MSI GT73VR, then unlock it with dislocker on the Vaio Z13 (no idea if it has TPM). It's weird that you can't access Bitlocker from Windows anymore, if it's the same motherboard and same drive, your password should work.

    It's possible it is something that only happens in windows, but yeah it happened to me. I just needed to input my key to unlock it, but it was a bit of a nightmare because I had stored my key inside, and the backup key in another drive so it took me some time.

    Then I was struck with a particular windows update that made me unable to boot properly from time to time, with a windows error of unable to find bootable media. I had to uninstall it.

    At the end of the day, it's all about how easily things can go south, so it is a good idea to have a backup. And more importantly (in my case) how my boot drive is more or less strictly a boot drive and I tend to have as little information as possible, so in the worst case I can reinstall the OS from scratch.

    Anyways, nothing particularly breaks, its just the extra hassle of having the key handy to unlock the drive.

    Maybe you got some checksum error? Does this sound familiar?
    I think that even if you remove the drive from the computer and put on another one with Windows it will allow to unlock it, even with USB to SATA adapter or M.2 to USB adapter too.
