Hi guys,

About a year ago I got a mate of my Dad's to fix my computer, which was all good and well except the idiot installed Linux on my system with a dual boot with XP. I've lived with it for a year but it's a pain in the a** having to sit at my computer while it starts up to choose to go to XP.

I've been reading around about uninstalling this partition but all either need the linux boot disk or the xp boot disk. I never had a linux boot disk and I can't find my XP disk and my CD burner is broken so I can't write to a disk.

How can I do this without using a disk?

The easy way is to use the terminal in Ubuntu/Linux to type the sudo cmd. as below.
You can uninstall but if the dual boot works, other than you wish to boot XP automatically, which of course at the moment if you did not select XP it would load Linux automatically the method to load XP is listed below.
A dual boot to Linux ( I use Ubuntu - which is a Linux base) is a good system. Linux has many advantages over Windows, not least the plethora of free software and the greater immunity from virus attack.

When you install a dual-boot of Ubuntu, one of the frustrating things that you’ll immediately notice is that Ubuntu is now set as the default operating system in the Grub loader. There’s an easy way to switch back to using Windows as the default.

To make this change, you’ll first have to boot into Ubuntu, and then run the following command:

sudo gedit /boot/grub/menu.lst

Find this section of the file:

## default num
# Set the default entry to the entry number NUM. Numbering starts from 0, and
# the entry number 0 is the default if the command is not used.
# You can specify ’saved’ instead of a number. In this case, the default entry
# is the entry saved with the command ’savedefault’.
# WARNING: If you are using dmraid do not change this entry to ’saved’ or your
# array will desync and will not let you boot your system.
default 0

The important line is the last one. You will need to change that number 0 to match the Windows boot section. Typically it’s always going to be 4 on a default dual-boot configuration. Change this value to 4, and then save and reboot your machine. You should go into Windows instead of Ubuntu automatically.

Note: The blocks at the bottom of the file match the items in the menu. You can change this value to match whichever item you want as default, just remember that numbering starts at 0.

To deal with removing Linux the easy way is with the XP CD. and is on the link below.
There are other ways, but I do not recommend you try them without knowledge.
The making of the Linux CD is not hard because you can make it on another computer and then use it on this one.
My advice is LEAVE it as it is if it works OK and simply alter the GRUB boot loader.
