W7 Pro 64 (6.1.7600.2.0.0.0 on HP w c300 128SSD at boot drive, - system failed to reboot. W7 start up repair failed; system restore failed. Earlier restore files clearly show the OS (SSD) as drive c: All drives test AOK including the SSD. I can see the data and the OS from command prompt.
The SSD drive - previously C: now is named G:-- c: drive had only temp files - I deleted those, on the theory that the drive lettering is now my problem, perhaps caused by the auto repair program renaming the drives.
I tried to copy the system files from g: to C: with dos commands, including ROBOCOPY but no joy. Access is denied - hyberfil.sys.
I want avoid a new install if I can. Is there any way to copy or move the system files from g: to C: or to rename G: as C:
(and rd c:)??
I have the command screen available from a W7 install disk.
Any help would be very much appreciated.
