No, that's not the way. Restart your PC using in MS-DOS mode booting from the installation CD of Win XP, then the Disc will give you three options: install, repair and uninstall (or format)

You need to format your computer's hard disk by doing this, then you can install Win 98 as you want.

If you don't have a Win XP installation CD, you will need a Boot floppy disk, insert a floppy disk in your floppy drive, open the Windows Explorer, right click on the floppy drive, click on ';Format'; and select ';Make a Bootable disk'; and click OK. This will cearte a Boot floppy disk. Then, restar your computer booting from the floppy disk in the floppy drive by pressing F9 and selecting the floppy drive. Once you have entered in MS-DOS, type A: and press the Enter key, then type ';format C:'; and you will format your hard disk and then you can install Win 98.

Be sure to back up all your data and files because by formatting your disk you will erase all the data on your computer, and you have to get the installation CDs of your favorite programs too. Because they will be erased too. I wish you luck. I hope my answer helps you and that you understand the risk of formatting your computer.How can i change from xp to windows 98?
stick in a windows disk and choose format. then shut it down and stick in the windows 98 disk and choose install. take note of sound drivers, you may need to seach for them.
Your best bet would be to make your machine dual boot. Use the Windows 98 to boot your machine into DOS mode and use FDISK to create a new active partition of about five gig. Install Windows 98 on the freshly FAT formatted partition and when you boot your machine you will be asked which OS you want to boot into.
