Cannot boot to c:\ drive--Please help.

[darkandstormy]

I was using Norton Speed Disk to optimize my c: drive (for the 1st time, as I've just acquired the package), when it came up with a file error, and asked me if I wanted to repair the error. I said 'Yes', and put the diskette in the drive so it could create an 'undo' file (which it did: ndundo.dat). Now when I reboot, is says that the disk (the c: drive, that is) is not a system disk and I need to remove it; I can't figure out what to do with the undo file.

Luckily I have Win2K on my PC as well (so that I can post this!), and I can use My Computer to voew all the files in c:\...I just can't boot to it.

Any suggestions?
