Professional Installation

Windows 98 will not recognize NTFS as a valid file system. Your best is to reformat the drive and reinstall 98. Use Fdisk off of the win98 E-disk to wipe out the NTFS partition, Create a new one and format, and install 98. You may be able to finda utility that will convert the drive from NTFS to FAT or FAT32, then you should be able to install Win98....but it definitely won't work as long as your drive is NTFS

Good Luck.

Too late now, but you could have dual booted 98 and 2000 as long as 98 is first. The only os that will run on ntfs is nt or better. The manufacture, like HP, should have compatible 2000 drivers for your machine depending on the age of the product.You could create another partition using partition magic and install 98 as fat32. This could save you from loosing all your data. Move the data to the 98 partion then delete the 2000 ntfs partition, then resize the 98 fat32 partition to full capacity then dual boot using fat32. 2000 gives you the option of which partition to use leave as fat32. It may be easier to just to reformat as indicated before if you have a backup of your data.
Good luck

Before you reformat and reinstall 98 just to get sound etc. Try going out to the Internet to download updated drivers for those items. It sounds to me like you may have an intregrated (video, sound etc) on board. There may be a recent upgrade for that board.... or items as needed.
W2K is very demanding as to what it will run on. You should have got a list of items that may have a problem on setup.
If you can update, that is your best bet. W2k on NTFS is very reliable.
