XP System Suddenly not bootable ... Unknown partition ... but partitally boots
Posted on 2006-10-30
Ok, I need some ideas on how to fix this, and some idea on what miight have caused this.
My wife was burning a DVD when the system blue-screened.
It rebooted and then comes up with an un-mountable boot partition ... but this is part way through the loading of the OS.
So despite its claim to be an unknwn partition, the system sees it and starts the boot process, I can press F5 and watch it load the drivers until it gets to the AGP driver and then up comes the error.
I tried running the install disk.
I booted into console mode and did a fixmbr. It tells me it is an unknown partition, I tell it to go ahead and fix it and it claims to fix it. I reboot and it has the same problem. Oh, it does not list any files on the C drive when I boot this way, despite their being accessible during the partial boot.
I booted into the install to try a repair and it shows me an unknown partition so the only option is to format ... NOT an option ... I NEED what is on the disk.
From the partial boot up I get the feeling the contents of the disk are there (otherise it wouldn't be able to boot this far and be trying to load the OS) but there is some issue with the partition type or something so that the OS isn't reading the files correctly.
So, again ... any ideas on how to fix this and what might have caused this to happen?
