How many OS do you have installed at any time...

That's amazing that you have 4 os installed.I have only two window xp and window vista

i use xp and i am planning to install ubuntu 7.10.I heard that it is really cool.I love 3d desktop concept.have any of you tried that?If so tell me how is it.

well myt friend you seem to be a very big fan of os on your computer. i have max installed 2 os in my computer. that was way back when xp was new. i had xp and 98. now i only have XP. so i think it suts best to me.

i have installed windows xp proffessional on my computer and i use microsoft virtual pc and installed server 2003 , win 2000 and ubuntu linux on my system.....

Prefer to use vmware or qemu when I ran another OS parallel, double installation is a little tricky should you need to swap OS quicky

I have only one OS that is window xp.

I only have one PC at home and it is preinstalled with Windows XP Home Edition

I tend to only run one OS system at a time. The reason why I do this is because of convience purposes. Having one OS system at a time loaded, allows me to fully engage in one thing at time, and thus, allowing me to have a deeper understanding of what I am actually doing with the system. It is in my best interests to do so. However, if I would chose to run two different 0S systems, then I would chose to run the OS X in combination with Windows Vista. This is a good combination because it has the reliability of the Mac OSX, along with the the market leader Windows Vista.
