Partition Magic reports error #1516 Partition improperly dismounted: "The partition dirty flag is set in a restart record in the journal file. This error may have been caused by a power failure or system crash while the Windows NT operating system was writing the partition. This problem can often be resolved by running CHKDSK /F on the affected drive." OK, but how do I run CHKDSK /F, since Win 2000 Professional will not boot? I can boot to DOS from a floppy, but DOS cannot see the NTFS partition. I CAN boot to the NTFS partition using Active@ Partition Recovery, but since I have no backup of the MBR, I cannot restore it. What I need to do is boot to the NTFS partition in DOS, then run CHKDSK /F. How do I do this?
