Win 7 Strange problem "Unmountable Boot Volume"

[Rob_NNCC]

Also, I would like to come out and say this: Unmountable boot volume does not always mean bad HDD. Most times for me the HDD is just corrupt. Usually I fix it and check the system log, and I find an improper shutdown...

Yep tired that too! I def. believe at this point it's the controller. I can't figure anything else after the process of elimination. I spoke with the customer this morning and she was going to check the paper work and see if she has an ext. warranty because she doesn't want to spend the money for a mobo. ...Ok customer just called while I was typing this and the warranty period is over and she's going to come pick it up and does not want to spend the money for a mobo replacement.

I agree that it doesn't always mean a bad HDD and I should have worded what I said a little better. But I do find that it's a bad hard drive or at least a failing hard drive alot of the time, but not always.

Sorry if I missed you mentioning this (and it appears that it's too late anyway) but did you try booting to a Windows 7 install disc and running a Repair? I don't know what I would expect it to do but it might be interesting. Might be fun to run /fixboot and /fixmbr on it as well.

Good point and I should have tried that....but instead......not sure if I mentioned this or not but I took the new hard drive with the newly installed OS (but still non-booting) out of her laptop this afternoon. I had a Toshiba laptop come in with a dead HDD, so just for grins, I stuck the new HDD from her laptop in the Toshiba and booted it up and.......it booted up just fine. No BSOD at all.

I think this lends even more credence to the motherboard problem....

Thanks!
