Hi All

My daughter has got a memory_management 0x1A error on a Lenovo Yoga Pro 7.

I am trying to recover the bitlocker key but cant find it anywhere. So tried to reload Windows 11 via a USB but it won't let me as I don't have the bitlocker key. I seem to be stuck in a loop at the moment and don't know what to do next.

Any help would be appreciated.

    Hello

    If you are doing a clean install from the USB key, you shouldn't need the bitlocker key.

    Make sure you boot the USB drive from BIOS, and choose t he install option > custom install.

    When prompted to select location to install, you want to delete every partition until they merge into one unallocated space, then select that to install.
