I needed to remove partitions from a Linux system in order to install windows. Here is how I did it.
- Boot the device from the Ubuntu installation CD. Ubuntu ISO images are located at:
http://www.ubuntu.com/GetUbuntu/download
You may have to enter the system's setup in order to make the device boot from the CD-ROM drive. - Choose English as the language
- Use the arrow keys to select the "Install Ubuntu" menu option
- Press the F4 key
- Select "Safe Graphics Mode"
- After Ubuntu boots up, quit the installation process. This will bring you to an Ubuntu desktop.
- Select the "System->Administration->Partition Editor" option from the menu at the top of the screen.
- Delete all partitions (extended and normal) so that there is only one partition remaining.
- Apply the changes
- Close the Partition Editor
- Restart the system by clicking on the power on icon in the upper-right hand corner of the screen and selecting restart.
