1) Go to www.microsoft.com, click on Support at the top and choose Knowledge Base and search for the error message you are receiving.
2) If you don't find anything helpful there, go to groups.google.com and search the newsgroup archive for the error message.
3) Use fdisk to delete the partition, create it again, then format C: if you don't need anything on the drive. You will need a bootable floppy to do this (format a: /s), then copy format.com, sys.com, and fdisk.exe to the diskette. You will also need your CDROM driver file, MSCDEX.EXE, and know the lines to put in config.sys and autoexec.bat *if* your system does not allow you to boot from a CD.
4) Alternatively, you could get Partition Magic, which is a great program if you want to play with partition sizes, etc.
Umm, all that will give him/her is a BLANK floppy boot disk
Did you mean to type: (format c: /s)
