Probably has to be launched from C Do you have a favorite partition table tool? A suggestion? Thanks for the reply and help Monton. Sorry - - not my area of expertise. Stand by, there are those here at Techspot well versed in this issue. There's a free version but it doesn't include a bootable recovery CD which you'd need. Do you have the Windows 7 x64 install disk? That first partition shouldn't be bootable and somehow got screwed up.
Good luck! That system partition shouldn't be bootable. In which case, the computer would boot from the second partition and it would become "C". Somehow, that system partition must be marked the Active boot partition, so it becomes the C drive and Windows trys to boot from it, but there's no OS in it so you get that message. With that chain of thought, I suppose you could also try a bootable partition recovery CD and make sure it's the second partition is the one marked "Active".
Reactions: SNGX Thanks for the suggestions. I tried to use Part Magic but was unsure of trying to change or even sure if I could change drive letters there.
Part of the problem of the scrambled drive letters was that I couldn't access the Sony recovery program to do a destructive recovery since it had to be done from C. Please be acutely aware however that in normal circumstances changing or deleting items in the MountedDevices key should not be tackled lightly and it is only safe under certain conditions.
In our case here with an already non-booting operating system we have little to lose and we should still be able to recover things manually by changing each line individually till we get it right and give our partition the correct letter.

When you say you did a system-restore in safe-mode, do you mean you actually booted Windows into Safe Mode or into System Recovery Options?
I booted it into safe mode before having this problem Drive swap — Brice. But in safe-mode, it should not be changing drive letters at all; the system drive should appear as C: as normal.
Had you done anything else that before the system restore? I uninstalled a couple programs. It could have been PowerISO, cause that was one of the few i uninstalled. After i uninstalled it in safe mode i restarted my PC again in safe mode. It loaded fine that time so i decided to do a system restore. After it finished, i started having this problem.

Just run the command diskpart lis vol sel vol select the volume number of the current C: partition [the old D:] inactive sel vol select the current D: [old C:] active Hopefully that will allow it to boot to the proper volume.
