I need to remove ubuntu from my computer,can someone tell me how to do this?

if you are dual booting it with any other OS
you can format the partition that hold Ubuntu

if you installed it using Wubi
you can uninstall it using Windows add/remove programs

THank you..... yes I am dual booting, how do I format the partition?

Do it in Windows. You will need to use disk manager to delete the Ubuntu partitions and format to NTFS as Windows is too primitive to use advanced filesystems like Ext4. You will also need to use your Windows CD to reinstate the Windows bootloader which Grub has overwritten.

Thank you.....I dont have a windows CD to reinstate the windows bootloader?

where do I find the disc manager, so as to delete the Ubuntu partitions? and format to NFTS?
cheers

If you bought a computer that came with Windows but not with a Windows CD, then you can probably order a Windows CD from your computer's manufacturer at minimal cost.

If you shrunk down your Windows partition when you installed Ubuntu (as is almost always the case when Ubuntu is installed on the same physical disk as a pre-existing Windows system), then you may want to expand the Windows partition to encompass all the space, like it did before.

You can use supergrub to add a bootloader then.

Right click My Computer -> Manage

How did you manage disks without it??

ok I have found the manager (I have never managed disks before)
now what do I do, I cant see anything that mentions systems or ubuntu?
and what is super grub?

I mean literaly, I need a step by step instructions on how to do this...if you have the time that is...
ok I am at this stage> i have right clicked My computer-> and have manage !

The Disk Manager shows you each of your physical disks, and the partitions they contain. You have at least one NTFS partition, for your Windows system. Leave that alone. Also leave any partitions alone that are before (i.e. shown to the left of) that partition on the disk. (There might not be any such partitions to the left of the NTFS partition, which is OK too.)

A default installation of Ubuntu will produce a big ext4 partition, followed immediately (i.e. just to the right) by a linux-swap partition. The Disk Manager probably cannot identify these partition types, so it will probably show them both as being of unknown types. Deleting these partitions will erase your Ubuntu system. If those partitions are shown to be contained within an "extended partition", and there are no other partitions contained within that extended partition, then you can remove the extended partition as well.

See http://www.supergrubdisk.org/ for information about Super Grub. (But I recommend you obtain your Windows installation CD and use it to restore the Windows boot loader.)

Thanks Eliah...well I managed to stuff up my computer, I wiped the ubuntu, then couldn't open my windows....which has turned out really great, as it gave me an excuse to get a new computer with a new system.... so all is good, Thank you for your help...
cheers colin

I'm glad you have a solution that works for you. Since it's often useful to have an extra computer (or perhaps you could sell or donate your old computer), please let us know if you want continued assistance getting that computer to work again.

However, if you consider this problem resolved, please mark this question as Solved. (You can reopen it at any later point, if you decide you want to resume working on this issue.)
