partitioning hard disk

I want to partition my hard disk so I can run have two operating systems on the same computer. I currently have Windows Vista on my computer but I do not like it. I want install windows xp on a partitioned section on the hard disk. While I do not like Vista, I want to keep it. I got it pre-installed on my new computer, do not have the windows Vista DVD and I might want it later. Can anybody recommend a good partitioning utility program and some advise on this?

 

You can resize partitions and create them from right in windows disc management. But a good place to start is to go to the pc manufacturer's website and make sure you can d/l drivers that are winxp compatible. If you cannot do that you might as well forget the idea as you will not be able to get xp running properly. This guide should help you, just go back to the first page for the guide. http://forums.techguy.org/windows-vista/583697-guide-installing-xp-win2k-after-8.html

 

Thanks. I have created a new disk partition 20GB in size labeled 'J' drive. I have formated it to FAT32. I could reformate it to NTFS if I wanted to.
Suppose I wanted it install windows 98SE in the new partition instead of XP, would I have to install Dos there first?

 

I have a problem. I have no floppy disk drive in my new computer, so creating a boot disk to install Win 98SE will become a problem. My computer does have a SD Card Drive and some other Removable Storage yokes.

 

Why would you want such an archaic operating system on the computer? Chances are it will not run win98. Its an obsolete OS. If you want an older OS, prob best to use WinXP. If you want an old OS like that, might a suggest a virtual machine which can run it as it will emulate compatible hardware.
