Hi All. I have been trying to get my HD to boot for over a week now. It crashed when I updated to Win10 from 7, and then tried to go back to 7. I have tried restoring and it did nothing. I have tried numereojus things like making sure the BIOS boot settings are correct, making sure I have the correct partition marked as active, system repairs (100 times), using the Bootrec command many times, Bootedit, sfc /scannow, chkdsk and more. Where I am stuck right is that when I try to boot from the drive, I get an error message that says: File: \windows\system32\config\system System registry is missing or corrupt. Status: 0xc000014c In spite of everything I've done, I can't get it to boot. I've had other error too, Status 0xc0000225, or 0xc00000f, or file \boot\bcd Status 0xc0000034 I am desperate to recover my files/emails etc and I think I should be able to get the HD to boot but am not having any success yet. Any ideas or suggestions ? Thanks.
