if you have installed the WinXP is very likely that the NTFS format, if the case would have to first convert it to FAT32 to install the Win98, in this case as well with this format you would recommend formatting the disk, formatted the eye alone noils the contents of the disc but not touching the partitions.

I format the disk to do so only with the installation CD for Windows XP, then I format the disk but I automatically install xp again.

I am interested uninstall xp, as I do ? How do I delete the record and so I get no warning.

Windows XP "Setup can not uninstall Windows XP. " because they lack the information needed for registration. "

Thank you very much

The disk you are using IDE or SATA, if the latter can give you problems, if there also saw drivers for your mainboard and other Win98, it should be an option for Win98SE using USB.

you can use to format a disk manager the Win98 boot disk, a Live CD or some type Partition Magic program.
