Hello,

after installing DriveCryptor Build v1.2 Beta 3 on Windows 10 20H2 (19042.572) 64 bit the os cannot boot.

I get stop code: INACCESSIBLE BOOT DEVICE

I tried two times - same result. 1st time old upgraded installation, second time new installation. HDD it GPT format.

Computer is HP EliteBook 830 G5.

Is secure boot disabled?

Turn off fast boot, see if that changes anything: https://support.lenovo.com/gt/en/solutions/ht501793
