Does Ubuntu replace Windows XP or can you switch back and forth?

Asked by Devin

Does ubuntu replace my existing operating system? If so, how would I revert back to my old one if I no longer want Ubuntu. My problem is that i use this computer for school and I need it in working order, and if I replace the op system, i'll be in big trouble.

For example, microsoft offers a virtual pc or desktop where you can load different operating systems such as vista, 98, 2000, or XP. I was wondering if this was possible.

Hi !

The ubuntu installer will let you choose if you want to erase everything or just make some room and keep windows.

See for more details

This is helpful but it is extremely complicated. Do you know of an easier, quicker way to do it?

:-) it is not... only really detailed.

Basically, you need to backup your data, then boot from the ubuntu livecd, and select the option "Resize IDE1 master, partition #1 (hda1) and use freed space" or something similar when asked for partiotioning options.

Wubi is an unofficial Ubuntu installer for Windows users that will bring you into the Linux world with a single click. Wubi allows you to install and uninstall Ubuntu as any other application. If you heard about Linux and Ubuntu, if you wanted to try them but you were afraid, this is for you.

I tried this a couple of months ago, it worked although I have since removed it.

Good luck.
