After HDD to SSD cloning both disks inaccessible boot device
Hello everbody, I have a problem that's really bugging me and I'm also (a little) worried bout the possible data loss, therefore I need your help. I used Acronis 2019 to clone my HDD running Windows 10 to my SSD (HDD 500 GB, SSD 512 GB). It all went OK, no errors reported. When I connected SSD to a computer (and disconnected HDD) I got a blue scren with error "inaccessible boot device" (Windows starts loading, but after some 30 seconds blue screeen of death appears). Ok, no problem, I will just reconnect my HDD and do it the long way...back up data, do a clean install etc. But the problem is that when I connected my HDD, I got the same error and now I cannot load to Windows from any of the disks and that's making me worry. When I cloned the disk, I added SSD as GPT and not MBR. Could that be the problem and can I repeat the cloning process with making SSD as MBR?
I didn't backup data before. I know I should have, but never experienced this before and have done quite a lot of cloning...
Thank you for your anwsers in advance. Hope I can fix this, beacuse there is some important data on that HDD. Marko

Hello Steve,
thank you for your reply and suggestions what to watch out next time I do cloning. Also next time definitely taking the backup/restore way.
To anwser your first question. I haven't made any progress regarding saving the partitions and Windows installation on neither disk, but I did manage to save data, therefore I backed it up and made a clean install on a new SSD (had to order new certificates though, but that is a small colatteral damage).
And since I have managed to save data and made a clean install, I haven't put any effort to find out the reason for things going bad. But if I had to guess I would say that HDD was MBR. Although I still don't understand why the HDD didn't work when I connected it again. I haven't changed anything in the BIOS by the way.
