Boot Config files missing

[TU920T]

hello, I have a Tosh U920 running W10. After an upgrade last week I have BSOD stating PC repair - BCD some files missing 000034. Tried windows install media with USB but error message - device not functioning correctly(when I know it is) Tried BCD scanos etc. rebuild etc to no avail. Its been suggested that the disk drive can be removed and new s/w installed externally???? is this possible? apppreciate any help, hate the thought of losing all my data. cheers Phil

Usual culprit for this is changing hard drives, say you take a hard drive out of one machine and put it in another, or it could be straight up hard drive damage.

Before you go buying a new HDD, try resetting the MBR or re-installing the OS. You vaguely refer to install media, but try these explicitly if you haven't.

I'm under the assumption that you tried to move over the hard drive as you indicate the drive is healthy. If that's the case, next time I'd recommend checking the config of the machines to see if they're a match and take the appropriate steps. Tools like Drive Cloner Rx and Acronis Image are there explicitly for things like this.

If it's not this and it's hardware failiure, well, you have to replace the drive. You can try cloning from the old to new to see if data can be saved. Drive Cloner Rx has a 30 day trial, so would recommend that. If that doesn't work you can try Recuva, but the chances of that working are slim so wouldn't put much weight in that.
