How to remove Ubuntu from a Vista dual-boot config

On my new PC I wanted (still want) to have toa go with Linux. I chose to experiment with Ubuntu. I downloaded thedesktop CD, burned it, freed up some disk space (inside Vista) andloaded up Ubuntu from the CD. After some experimenting I figured outhow to install Ubuntu in the empty disk space and it all worked fine(GRUB took over my booting (recognized Vista automatically!) and Ubuntuloaded up fine).

Then I tried to install my GPU drivers andeverything went wrong.. For some reason Ubuntu wouldn't boot anymore(failed to load X-Server or something). I was completely lost andwanted to remove Ubuntu.

This is where things start to get really messy!

Ifyou simply remove the Ubuntu partition, GRUB (Linux boot loader) willstill be on your PC (in control). It will trip out, as the Ubuntupartition will be removed.. Bad thing!

So you need to restore your Master Boot Record (MBR) for Vista (so that Vista will handle the booting, not GRUB).

Googleonly pointed me to sites that explained how to REMOVE VISTA, whichisn't what I wanted. Many sites talked about the 'fixmbr' command, butthis is really only available in Windows XP.

So how do you restore your MBR for Windows Vista?

1. Put the Windows Vista installation disc in the disc drive, and then start the computer.
2. Press a key when you are prompted.
3. Select a language, a time, a currency, a keyboard or an input method, and then click Next.
4. Click Repair your computer.
5. Click the operating system that you want to repair, and then click Next.
6. In the System Recovery Options dialog box, click Command Prompt.
7. Type Bootrec.exe /FixMbr, and then press ENTER.

That'sit. Now when you reboot your PC, Vista will load automatically... Youcan now safely boot using your Ubuntu desktop CD, to use the built inGnome Partition Manager to remove your Ubuntu partition!

If you run a dual-boot system with Linux and Windows, this has happened to you. You had to do your monthly reinstall of Windows, and now you don’t see the linux bootloader anymore, so you can’t boot into Ubuntu or whatever flavor of linux you prefer.
Here’s the quick and easy way to re-enable Grub.
1) Boot off the LiveCD
2) Open a Terminal and type in the following commands, noting that the first command will put you into the grub “prompt”, and the next 3 commands will be executed there. Also note that hd0,0 implies the first hard drive and the first partition on that drive, which is where you probably installed grub to during installation. If not, then adjust accordingly.
sudo grub
> root (hd0,0)
> setup (hd0)
> exit
Reboot (removing the livecd), and your boot menu should be back.

Only read below if Windows is now missing from the boot menu
If you installed Ubuntu before you installed Windows, then Ubuntu will not have anything in the grub configuration for Windows. This is where you’ll have to do a bit of manual editing to the grub boot menu file.
If you open the file /boot/grub/menu.lst with the following command:
sudo gedit /boot/grub/menu.lst
You’ll see a sample section for Windows, which you’ll want to uncomment and add to the boot menu list in whatever position you want it in. (uncomment by removing the #’s)
# title Windows 95/98/NT/2000
# root (hd0,0)
# makeactive
# chainloader +1
Note that you should also verify that hd0,0 is the correct location for Windows. If you had installed Windows on the 4th partition on the drive, then you should change it to (hd0,3)

Its GRand Unified Bootloader used in Linux OS.
Normally you get this error when GRUB is not able recognise the partition from which you are trying to boot the system. Make sure the boot partition on your system is recognisable by GRUB (such as EXT3).

You can try to restore the GRUB using the LIVE CD

1. Boot From Live CD
2. Open Terminal Window
3. type >sudo grub
4. then type : find /boot/grub/stage1
5. you'll get something like: (hd0, 1)
6. then type : >root (hd0, 1)
7. type: > setup (hd0)
8. >quit
9. >exit

Remove the Live CD and reboot the system.


Please let me know if you need any further assistance.


Thank you for choosing Fixya

- reboot with LiveCD
- in CMD run command fixmbr, fixboot
restart, load Windows XP.
OR in Unbuntu Grub write XP portition

Try running the command grub-install or if that fails, try the help command

You could also boot off the Ubuntu CD and be able to reinstall grub

It has the latest mouse driver (logitech setpoint 4.0). Before installing Ubuntu the setup worked w/ SUSE/XP using GRUB dual boot. After installing Ubuntu XP does not see the usb mouse. Even Logitech setpoint does not have the mouse setup/configuration option. It appears that at boot it does not recognize the mouse or disables it. The BIOS has the usb keyboard and mouse enabled. Currently, I have two mices one for xp and either mouse will work under Ubuntu.

While in Ubuntu do:

sudo fdisk -l to find the drive you want to boot to.

On the command line type:
"sudo grub", this will give you the grub shell >

If the disk you want to install the MBR is sda* for instance, then type (at the grub prompt):
"setup (hd0)"

then type "quit" at the prompt.

Do you have any other OS's installed? Its with the Grub. mostly looking for another OS. let me know.
