I found this doing a Google search:
First, I would like to thank our friends at microsoft for putting out another great product, windows xp - more bugs than ever! (if you cant tell I am very frustrated, after working all day I find my own computer is jacked beyond my knowlege).
I get the BSOD, unmountable_boot_volume error when I start up my computer. Tried Safe mode, and last known good configuration. I found on microsoft that it needs 'chkdsk /r command from Recovery Console '. The issue is, microsoft in their infinate wisdom decided to make XP not bootable so I am left a broken and hurt man. And, Compaq in their wisdom (I am serious) decided to throw away floppy drives since they are 10 years obsolite(it just happens that the rest of the world doesnt agree). I need help with this. I tried a '98 boot disk burned on a CDrom. I tried the XP boot disk burned on a CD rom, no luck. Any way to get this thing to work, ASAP so I can have my life back?
Thanks for your help
