Windows with Bitlocker powers off when booting or at password prompt



A while back I installed Windows 10 Pro and set up bitlocker (without TPM hardware) so it asked for a password during boot. Things seemed fine at first but for some reason the system started spontaneously powering off during the boot at what seemed to be random intervals. Sometimes I wouldn't even make it as far as the bitlocker password prompt. Sometimes I might even get my passphrase in quickly and everything would boot up normally. But most of the time I would see the prompt and only get a few characters in before it powered off.

After hunting around, I found this solution in this thread. Open up command prompt window as administrator and type in this command:



bcdedit /set {bootmgr} bootshutdowndisabled 1

This did the trick.Then the recent Windows 10 Creator edition update was applied, things were fine for a week or two, and then it started happening again. So I had to type that command in again. Fingers crossed...
