Help with uninstalling ubuntu

Asked by Jinesh

Ubuntu is a great system its really good but i had few problems and so want to uninstall it. Now the real problem is that don't see any uninstall option in my windows add/remove in control panel to uninstall the Ubuntu. Little information about Ubuntu: i installed the newsiest version out there i think 8.10( not sure but its the new on the web), installed it in a different hard drive which is 12 gb slave drive.

This is what i tried to do:
              took out the hard drive which was slave drive and formatted it through a different computer, then when i putted it back in the primary computer as a slave and it wouldn't let me go into windows xp because the Ubuntu menu wouldn't load up.

              after that i again installed it on the same slave drive (12 gb), and now it works fine but want to uninstall it

Thank you

In Windows , Install a program for managing Disks like Power Quest Partition Magic ,( or any one else ) , select your 12 G disk and Format to NTFS , after formating windows will recognized your disk. ( you will lose everything on that disk , i guess its what you want ????).
Hope i help.

Dear Lisandro

What you said up there i already tried but what happens is that when i boot it up the ubuntu menu comes up and it wouldn't load up and there is a error. So i can't go in either Ubuntu or windows Xp proffessional.

Thank you

Since Ubuntu is installled on the slave drive you can just reformat it like you did before. The only other thing that you need to do is to remove grub from the MBR of the windows drive and replace it with windows bootloader.

There are many ways that you can remove grub. Typically you would just boot with Windows Install CD in the drive and select Recovery Console. When you get to the command prompt, enter the command

For XP ->fixmbr
For Vista ->bootrec /FixMbr

If you are having problems using you Windows Disk there are some alternative for restoring you windows MBR. For example you can use

Super Grub boot disk
ms-sys from inside ubuntu
MBRFix.exe from inside windows

This page provides information on alternate methods
