OK...are you going to answer the questions I asked about the partitions?
The link was just for informational purposes, to show you that you are not the first or last person who encounters this situation.
Do you have a Microsoft XP install CD?
That message you posted...it looks like part of your boot.ini file, quite necessary for the system to properly boot. I don't understand why that should appear onscreen at all. Maybe that's where the boot process halted, I've not seen that before.
Seems to me that you need to move some files right away, since chkdsk stopped due to lack of space. That should be your first priority, IMO...moving files from the C: partition.
Remove the hard drive from your system...and temporarily connect it to another working XP system. You need to move enough files from the CP partition that there is at least 15% of the total partition space vacant.
While you have your drive on that system, you can run chkdsk /r from the command prompt on your drive...and hope that rectifies something (it won't hurt anything).
