Windows 7: windows 7 boot loader missing/corrupt

meant to say list volume (not volumes)
The screen shot shows you can get quite a bit disk information from the command prompt.

Try doing what I did in my last post/screen shot
But your info shows you have the 100MB system reserved partition. This contains the boot folder and the boot manager. It also has a letter assigned which it shouldn't - see mine. Furthermore it's c:.

The last column (see mine) under info shows the the 100MB is system (active) & beneath it is boot.
(The MS terminology gets a bit of flak from some. "boot" is where the operating system lives and the boot loader winload.exe. "system" the boot manager and boot folder (with the BCD inside it))

Hold off on the letters for the moment. Your running cmd from the repair disk or Win7 disk - correct? So it's probably arbitrarily assigned letters.

Ok so command line operations on C: will target the system reserved partition. Command line operations on E: will target your OS (label C: when windows is running).

yes, from the tools section of the repair disk, or Shift F10.
So do you think that the Volume letter could be causing an error when trying to repair the startup?

At this point, it seems like my only option would be to try and get my files into an external HDD, and just format the entire drive?

Grub isn't stored in a partition. It's stored in the boot sector.. the very first sector of the HDD. Otherwise gregrocker has the correct advice. The fastest and easiest way to restore the windows bootloader after removing another bootloader is to boot to the windows 7 install disk, type shift+f10 to open a command prompt then type:

Bootrec /fixboot
Bootrec /fixmbr
Bootrec /rebuildbcd

It works every time.

Number one priority is getting your files safe. After that we've got nothing to loose - agreed? Going back to scratch format, etc may be the pragmatic solution.

Do you need any assistance getting your files off the disk???

Yes
But I thought they said they had tried that.
If not do it of course.

Yes, we've tried it - I said in an earlier post it works 100% of the time for me also. /fixmbr is all that's needed.

I've been looking over various forums and when it gets to this stage I am yet to see anyone fix the issue without a reinstall.

chbell has a lot of patience, I'd have wiped it long ago
