First of all, do you have Win98 or WIn98 2nd edition. If the latter, then there won't be any problems reformmating your HD. If the former, then you have to update your version of fdisk as in this article:
This will install a FRESH COPY OF WIN98 on your drive with NOTHING ELSE> Your PROGRAMS, DATA DOWNLOADS etc will be GONE. You'll have to reinstall everything, including all the drives for your hardware that is not integrated into Windows 98.. Make sure you have all your files backed up BEFORE you start this, inculding your email, address book, favorites, game saves, accounting information - yada yada yada. Programs will have to be reistalled, so make sure you have all your install CDs/Floppies available. Of course, if you have a brand name PC, like a compaq or ibm etc, then you should have a restore CD with all the original programs and drivers on it.
BEFORE YOU DO THIS< IF YOU HAVE ANY DOUBTS OR QUESTIONS ASK BEFORE YOU REFORMAT YOUR DRIVE. AFTER YOU REFORMAT YOUR DRIVE, IT WILL BE TOO LATE.
To reformat your drive, set your computer to boot from CD in the bios or boot from a Windows 98 boot floppy with the Win 98 cd in the drive. When the various choices come up, select boot with CD support. When the cursor comes up, type the following:
A:/>D: (where D is the drive letter of your CD-Rom drive)
D:/>CD win98
D:/win98>format c:
You should then get the format command sequence and can reformat the drive. Once the drive is formatted you can then type:
D:/win98>setup
and setup should start up. Follow the istructions on screen and have your WIn98 serial number handy.
ANY questions - ask now, before you reformat!
