Windows 7 won't boot. Please help

Here's the situation:

For a while I have been having trouble with the blue-tooth driver on my t510. While trying to update its driver (I was having problems with my bluetooth mouse), I got a a weird error message. For around 3 months while booting Windows I'd get an error couple of months message stating I was missing a .dll and in device manager most of the bluetooth drivers had an "!" which a yellow triangle. Today was different. I didn't get that message and the bluetooth section was not in the device manager. I found this strange so I tried updating my bluetooth driver again. Same problem.

Then I saw that on the lenovo bluetooth driver page, it stated to try uninstalling the thinkvantage bluetooth and then reinstalling. I was not able to uninstall it since, again, it stated that a file was missing. Then a Windows 7 window popped up saying it was installing (not even sure) something for bluetooth. After the update I clicked my the start bar to access the add/remove window to see if the bluetooth section was back. When opening the start bar, I noticed none of my files were there. I went in my music folder when 2 of my ~7000 songs were there. Firefox didn't work. I panicked.

I restarted my Windows (I dualboot with Ubuntu btw) and got the error: Oxc000000f and it couldn't boot. I tried doing the repair with my Windows DVD. It didn't work. It said the file compbatt.sys was corrupt. Then I logged onto Unbutu to check my Windows partition and noticed that bunch of my stuff was missing. I panicked some more.

After I tried to repair again with the Windows 7 DVD and managed to do a windows restore but it didn't fix the problem. So the I found this page:
How to use the Bootrec.exe tool in the Windows Recovery Environment to troubleshoot and repair startup issues in Windows

I followed their instructions using the command prompt. After restarting the computer and choosing Windows from the Linux grub menu, I was presented with a page that told me to choose between two OSs, both said: "Windows 7 Professional". I found that odd. The first one yielded the same error: oxc000000f. The second one worked. But it was a different profile and I was missing most of my stuff, all of my think vantage software etc. When going to the program files I also got another error: "File NvCpl.dll is corrupt".

What do I do guys? I have to much crap in my Windows partition (such as school work). I can't lose it. Do you guys have any solutions?

 

I was checking the net and found there is a serious problem with the bluetooth driver that lenovo provides. Some people have had a similar problem for multiple months. Lenovo you couldn't fix this?

 

nvcpl is related with ur nvidia driver. what u done actually installing windows on top of another windows. thats why u get 2 listed of win 7 profesional. if u familiar with the windows profile. u can copy ur profile into the 2nd windows that u just isntalled.

 

A proper backup of the system image would have saved you from these problems.
