since last sunday I've got a problem with my PC after I connected an external HDD.
After connecting everything was fine, I copied things on the HDD and from the HDD to my PC. On my setup: I've got 2 physical drives, one has 120GB (this is where my Windows 7 is installed) on drive-letter C and a 1TB-drive for everything else (drive-letter D).
In the middle of the copy-action a bluescreen popped up and didn't stay for a second so I can't say what there was postes in the errormessage. At this point I was just concerned about the files I just tried to copy, I didn't know that this would be my smallest problem.
After the restart I got the following error "DISK BOOT FAILURE. INSERT SYSTEM DISK AND PRESS ENTER". You don't like it when that happens. After I found my system disk and inserted it: Nothing. I tried to boot with and without the external hard drive, always the same error.
I then tried to fix my MBR with the recovery console, this helped nothing. But I found out, that my Windows now hat the drive-letter E and not C anymore. C now was the system-reserved partition. After googling I found out, how to assign new drive-letters with the recovery console, so I did:
diskpart list volume select volume * assign letter=C
I restarted and: it worked!! Everything was fine like nothing ever happened. But then I restarted. And I got the DISK BOOT FAILURE again. I tried the same thing with diskpart like before since I needed some data from my D-drive and hat no live-disk at hand. But this time, it didn't help. Same error. Since I need my PC I formatted my C-drive and installed Win7 again. Since all my data is on another drive, this is not that big problem for me. Install was successful, everything went fine. But then I restarted. Same error again.
Alright, and now I have no clue, how the solve this problem. Can anybody help me?
