I have a most curious problem... I got into work today, turned on my laptop and started going through my emails... (in Vista) Suddenly, the laptop froze (which never happens)... so I held the power button for 10 seconds, restarted and now it wont boot. I get apples grey screen, followed by the "select the partition to boot from screen" and then nada... Choosing windows boots to a black screen... Choosing osx boots fine... So, this may seem like the windows partition go corrupt... not problem I keep backups of everything... Pop in the vista disk, boot off the Vista disk... and I get the same black screen! Short of formatting the HD... any ideas? (I've tried flashing the PR ram, which seemed to be apple's fix-it-all solution a while back...) M. EDIT: ... Cluster accounting failed at 40364588 (0x267ea2c): missing cluster in $Bitmap Cluster accounting failed at 40364589 (0x267ea2d): missing cluster in $Bitmap Totally 2049 cluster accounting mismatches. ERROR: Filesystem check failed! Windows wasn't shutdown properly or inconsistent While trying to make an image of that partition, I got a few errors... now, to resolve that all I need to do is run checkdisk... problem is, as I can't boot off the CD I can't run checkdisk... ideas?
