Want to create multiboot

I have a computer with a hard drive that is windows XP pro and an old computer with 98. I put the hard drive with 98 on my pc and I will like to make a multiboot to choose which OS I want to start the computer.

Can someone help me ?
Thanks

I know Windows too, but the utility multiboot Vista it is not available separately.

you need to repair XP with CD or partition relocation. normally it will detect and make the multiboot. do it with xp, 98, na it not work.

You have to install each operating system on a separate volume of your computer so that each installation can retain its own files and configuration information.

Make multiple operating systems boot through a common boot partition. Third-party boot managers, in contrast, typically keep OS partitions completely separate and boot each OS completely from its own partition. A few sophisticated third-party solutions may make use of proprietary disk partition tables. This abnormal approach may permit you to create lots of partitions and install lots of concurrent OS's, but it comes at the expense of compatibility with other common disk utilities such as fdisk, PartitionMagic, Norton Utilities, Ghost, DriveImage, TrueImage, et al. Proprietary partition handling effectively "puts all your eggs in one basket"--if the boot manager fails, you're in trouble because no other disk utilities will work. To understand the ramifications of these various approaches, we first need a little background.
