|Go into the bios Setup and see which hard drive is first in the boot order. If there is only one hard drive listed there, find the list near where the boot order settings are - the models of the hard drives are probably listed. If the top hard drive listed is the one XP is on, you just remove the hard drive 98 is on . The multiboot choices will still be there when you boot - the Win 98 choice just won't be valid anymore. |
(If the XP drive is IDE you may need to change the jumper setting on the back of the drive too, if it was on the same data cable as the 98 IDE drive).
You can remove the second operating system choice from the multiboot menu by simply editing boot.ini in XP.
Control Panel - System - Advanced - Startup and Recovery - Edit - you MUST maximize the window
The default choice is listed at or near the top of boot.ini - since you say that's XP, you want to delete the entire line below [operating systems] that is NOT the same as the default one.
(e.g. if there only two lines below [operating systems], if the first one is the same choice as the default, delete only the lower one)
Choose File in the top left corner - Save.
If after editing boot.ini there is now only one operating system listed after [operating systems] in boot.ini, after you reboot, your computer will now boot without prompting you to select operating systems.
