Unmountable boot volume

[smr]

I've just bought a brand new pre-built computer

It had no OS so I installed Win 10, which I then upgraded to Windows 11. Turned it off and on multiple times and it was fine, plugged in the HDD from an old Computer and transferred documents etc.

Unplugged the drive... Turned the computer on and off a dozen more times, installed all Windows updates, turned off and on again, all fine.

Then an hour later turned it on and it says Unmountable Boot Volume - it's an M2 SSD and it's detected when the computer posts.

wtaf?

I had some weird behaviour yesterday. My PC tells me that there's an IO error and to add in removable media. What removable media?

Windows boots just fine if I skip the bootloader so I head over to the recovery console and do my best to fix things up in command prompt.

I can get back into windows now but it does feel like there was an update to something that frigged the bootloader

SSDs, they be awesome.

On a serious note, you did make sure boot order is all good after removing the HDD and you don't have any USB sticks left plugged in?

Did the old HDD have an OS on it?
