SunPCi User's Guide

Disk Error Messages

If your SunPCi window shows the message Non-system disk or disk error at startup, your C: drive may have been corrupted, or you have a non-bootable floppy disk in drive A:. If you do not have a floppy disk in drive A:, delete the default C: drive file in $HOME/pc and then restart SunPCi.

You may want to make periodic backup copies of your C: drive. Refer to Backing Up Your C: Drive for more information.
