Tried using WinToFlash. Apparently it does not support Win98.. is there another way around this? Or am I just going crazy? I can confirm that it works with winXP since I recently did an install for an old Acer notepad that got its hardrive broken, the hardrive was a a SATA by the way.    I'm checking my install of WinToFlash, yep it doesn't have an option for win98 setup, did you try with the Transfer Windows XP/2003 setup to USB drive option to see if it actually recognizes the win98 disk?  Failing that I'd try create bootable MS-DOS USB drive and then manually copy the contents of the win98 disk into the USB drive, back then windows still was running on top of MS-DOS, so it makes sense booting on MS-DOS and then using the command prompt to start the win98 install...     Then, IF you succeed, there is the issue of how well Win98 can handle hardware of a modern computer, at least most crucial ones like input, video card etc. Are there even drivers for e.g. a relatively modern Nvidia graphics? How will it handle a modern CPU, motherboard? Will it even see your HDD, if, for example, it is SATA2? I'm not sure. Now that you mention this, if I recall correctly the main issue I had trying to run Dungeon Keeper on a modern machine was that the winXP (or was it win95 or 98??) emulation wasn't able to recognize the modern audio and video chipsets... in those times you had Sound Blaster audio drivers and no graphics acceleration whatsoever... :D    Also wanted to mention that Norton Ghost is a great tool for saving images of your hard drive in cases when you need to back up and wipe an install, if you want to go back to what you had without having to reinstall the OS again, with a good ghost image you can get your drive back to how it was in 5 minutes.    The  radified guides  for partitioning and image creation are great for this type of fiddling with your drives.
