Bios Update now no Desktop

Hope I put this in the right place. Here goes...


So I updated my bios today from 1.7 to 1.A. When the system restarted it goes to Windows 7 with a black screen that says "C:\windows\system32\config\systemprofile\desktop Refers to a location that is unavailable". From here I have all of the basic buttons but I cannot access anything. I get an error even trying to run regedit. My system ran fine before the bios update. The system setup is as follows:


50GB SSD with Windows 7 installed only
4x 500GB HDD in Raid0 with all user profiles and default save locations set to it.
2x External drives (not to important here just run Ubuntu and a spare drive)

When I set the system up I changed all of the registry settings so that windows automatically saved everything to the Raid0 drive. Everything is still on the drive as it has been unchanged but Windows fails to find the desktop settings now. How can I change this? I CANNOT lose any of the files so a wipe and rebuild are out of the question. I'm lost here fellas and could really use your guidance. Thanks in advance.


Edit: When I looked in the system profile folder there was no "desktop" folder there. I manually created one and got some of my shortcuts on the desktop back but everything is still missing. At system launch I edited all registry settings to point to drive D: as the primary. Maybe something changed there?

Thank you for replying. I have gone through the bios and everything is set accordingly. The issue is with windows not recognizing the proper drive with the user profiles. I think the registry has swapped back to the C: drive instead of the D: drive. Only issue is I don't know where to begin with it.

IMO, The BIOS update has un-build the RAID.

I personally would stay away from RAID, as it seems to more problems than it is worth.

The Raid array is actually fine. Window seven recognizes the drive just as it did before. The problem is with the registry not direct properly anymore.

As suggested the BIOS updated reset to optimized defaults, so you'll need to find the setting change which affected the RAID drive's linkages from SSD or reimage or clean reinstall the OS.

One of the benefits of having the data moved off the OS drive is it makes a lean image which is easily reimaged and holds the links to data HD which remain current. I'd take advantage of this in the future.
