Ok, I'll try to be as thorough as possible for this one. I've looked over some of the posts in related issues, but seem to lack some aspects of what I am dealing with. I'll post the issue and keep looking while I wait for a response...
I'm working on a Vista laptop. No updates/new installs/whatever done and it worked fine for the 3 days I had no internet access (so no web/e-mail viruses). Here is the progression after that point:
-Powered up like normal, and system hung at black screen after initial part of boot-up sequence.
-Manually powered down with power button, rebooted, and was taken to system recovery. I did a restore to last point and rebooted.
-System will get to password screen after 30 mins of working. When I input my password, it would process (HDD was working the whole time) but eventually stay at a black screen and eventually the HDD would also stop, with no resolution.
-Everytime I boot up now, the Lenovo system repair comes up and asks what to repair. The only option is Vista boot but doesn't do anything.
-I got a Vista install disk, thinking I would try a repair. When I put it in, it DOES recognize the disk and try to boot from the disk (shows all drivers loading and gets to the microsoft windows back-and-forth progression bar), but eventually just hangs at a black screen.
I finally got it to boot start booting up into safe mode with command prompt...but it hung at loading crcdisk.sys then gave me a bsod that told me I had an "unmountable boot volume"... I tried to pause the screen to see the rest of it, but apparrently it doesn't respond to the pause anymore.
I have read bits here and there mentioning the crcdisk.sys issue as well. Does this help clarify the issue for anyone? Does anyone have any suggestions or ideas?
I've tried a boot disk and was able to get into my HD just fine, so it appears to be mostly a Vista issue.
--I've read a couple posts telling people to take their memory down to 2 Gig or less until Vista could be repaired...tried it and no effect.
--I've also tried reseating the HD, but with no effect.
--Next I'm going to try using the XP install disk (yes, XP, not Vista) to see if I can use it to get far enough to use the Vista repair. I'll post what happens for future generations of frustrated Vista owners.
Well, I'm a little disappointed that I'm the only one who troubleshooted or responded to my dilemna, but such is life...
For those who come after me, here is the final prognosis...
--The XP repair disk WAS miraculously able to boot, but didn't help at all in restoring anything and basically rejected the idea that it could help.
--After running a few tests with a couple diagnostic programs (from super boot disk and others), it was shown that the hard drive had a bad sector within Vista's hidden partition...resulting in a HD that CAN be accessed from non-Windows programs, but canNOT boot up... Lenovo is sending me a new disk, and I am using the a converter to use the disk as an external HD until I can get the rest of my files off that I want to keep.
Not at all the resolution I would have wanted, but I hope this helps someone!
(Incidently, DiskDigger, a FREE download from PCWorld.com, was IMMENSELY helpful in recovering a ton of info from my HD).
Had I seen your post, I would have advised that as soon as you see "Unmountable boot volume" that usually means hard drive failure. Not necessarily total failure... but definately enough to cause problems.
