Installing ubuntu inside windows (i hv demonstrated how to install 10.10, the only difference is you will see 11.04):

• this window will open then:

• click install inside windows. then this will appear: now select the drive in which you want to install it

• installation size: give how much space you want for ubuntu, REMEMBER, you can not change this space after installing, so better give some 20GB, or atleast 10 GB!!

• enter user name:

• DO NOT CHANGE 'Desktop environment'. just enter the password you want twice

• click Install

• reboot, and select Ubuntu in the list!!

After your computer restarts, choose 'Ubuntu' from the boot menu.

You can uninstall Ubuntu by going to 'Add or remove programs' in windows xp.

NOTE: all changes will be lost in ubuntu if you unistall ubuntu.
