Format with the Ubuntu 10.10 Live CD

In this tutorial you will learn, to format, enlarge or reduce the size of a partition, especially the system partition (which can't be done using the Windows partition manager).

Warning: Make sure to save your important data on an external drive, as any mishandling may lead to the loss/damage of your data.

Note that:

• If your system has a dual boot (several OS), formattin the partition might erase the boot loader of one of the installed OS.
• If you accidentally deleted the bootloader you will need to re-install GRUB.
• If you have XP: Repair the Windows XP startup.
