\Boot\BSD issues

Question

Hello,
I was recently mapping network drives to my windows 7 machine through windows exporer. I mapped two drives, I cannot remember exactly but I beleive they had the letters Y: and X:.  on researting the computer, I got a bootloader error, with a black screen
saying there is a problem with \boot\BSD. I have read quite a few posts, including the very helpful ones at :
http://social.technet.microsoft.com/Forums/en-US/itprovistadeployment/thread/8647c865-59a2-44dc-8be2-1a65731bbe38
and the manual restore help at
http://support.microsoft.com/kb/927392
for another method of manual restore of bootloaders, the follwoing website gives some good instructions as well:
http://neosmart.net/wiki/display/EBCD/Recovering+the+Windows+Bootloader+from+the+DVD
And for anyone else having a similar problem I suggest you start here.
BUT my problem is that none of these will work for me. In the windows Recovery console, there are no versions of microsoft windows listed, and all the atotmated startup repair options fail in the following ways
1)On starting system repair, a dialog comes up saying it is searching for windows instlalations. It finishes and says that there are problems with the computers startup options, the details say:
The follwoing startup option will be repaired:
Name {bootmgr}
Identifier {[long hex string]}
The following startup options will be added
Name: Windows 7 Home Premium (recovered)
Path:Windows
Windows Device: Parition=C:
Name: Windows Recovery Environment (recovered)
Path: Recovery\[long hex string]\winre.wim
Windows Device: Parition=C:
Unfortunately when I hit repair and restart it throws an error saying "failed to save startup options"
2) No OS's are shown and so the atuomated recovery tools cannot run
3) I do not have a system image
4)In the advanced menu, Startup Repair fails, the detials suggest that it cannot find the OS
5) when I try to go to the command prompt to fix it manually, it starts in X:\Sources>    however it won't accept any keyboard input (Keyboard input works outside of the windows recovery conolse, and it is a USB keyboard), so I can't do the
manual option either.
I have backups, but am trying to aviod re-installing all my programs and doing a full wipe/restore as I will loose some data and a lot of time. It looks to me like my computer has forgotten where the C:\ is.
I also just ran DOS Sea Tools on the hard drive, and it says that it cannot find the drive. However, when I go into the load drivers menu in windows recovery I am able to get into the C:= drive and see all my files
Any help would be appreciated
Cheers

Hi,
It seems this is caused by BCD data corruption, but it is odd that you cannot use keyboard in command prompt. I suspect the Windows recovery console is severely damaged.
How about another keyboard?
Do you have any system restore point? If so, try to perform a system restore for a test.
If all steps fail, the suggestion is to use the backup to restore Windows 7 to a normal state.
