After successfully installing SP3 for Windows XP, I'm getting "Loading PBR for descriptor 2 ... done" when I boot the machine. The machine has gone on to successfully boot, but I'm concerned about a problem with the primary boot record.
Sometimes the machine does not successfully boot and I receive the blue screen with an "irql_not_less_than_or_equal" error. If I keep rebooting it a few times, it eventually boots.
I've done a chkdsk upon boot and everything seems fine.
What should I do next?
