How can uninstall grub 1.5 of my laptop

the error is 22

Besides partitions there is a thing called a boot-record. It usually contains just enough code (its really small) to launch a boot-manager somewhere of one of your partitions.

It still points to Grub (the Linux/Ubuntu bootloader) which you have removed. (it was part of the the Ubuntu system)

It has to point to the windows-bootloader instead of grub.

So, how do you fix this?
  - fire up that recovery cd
  - choose repair/recover (its called something like this)
  - choose repair bootloader

Now, Vista will boot correctly.

Just out of curiosity, why didn't you dual boat? You can have both Ubuntu and Vista installed... or did Ubuntu not satisfy specific needs?

I want to do dual boat but went i start to boot grub does't recognize windows vista so i can't enter to it!!!!!!If you have any answer to this problem it will be apreciate....thanks!!!

I used the recovery disk, but it didn't give me the option for repair. It just start to format the hard disk and install windows again. But the problem with grub is there again......

So, its more like a backup disc than a real vista installation disc?

Thats a bit problematic. You need to get a real vista installation disc. Perhaps you can make a system-repair-disc on somebody else's vista machine.

A windows XP repair wouldn't work, since Microsoft changed the bootloader with Vista .. although you could try (it might just work)

We are talking about either real offical installation CD's from Microsoft (not your computer's manufacturor) or a recovery diskette made under windows. Not a backup disc but a recovery disc: one that has fdisk on it or something simelar.

But if you want to do dual boot that might be an easier solution.
... you seem to already have vista installed (even though it doesn't boot)

If you reinstall Linux as a dual boot option you will be able to boot into both systems.

You might need to tweak something by hand, Vista is kind of anti-linux, but it should be possible.

So try to reinstall, and then come back here and we'll try to make sure grub boots you into Vista as well .. You might need to edit /boot/grub/menu.lst from within Ubuntu. And we might need to mark the vista partition as 'bootable' using gparted. But at this point reinstalling ubuntu and thereby restoring grub will be the way forward (if you still want to dual boot)

Make sure to choose 'resize' windows partition, so you don't overwrite it. Otherwise you have to reinstall vista again..

Fiscal, even though the following references are not Vista specific, you may wish to have a look at them as they deal with Windows and Ubuntu dual booting.

Alan Pope has done a very nice screencast video that walks you through the process. http://video.google.com/videoplay?docid=-2369893842637434537

Also the wiki page is a very good reference.

ok boys:

I installed Windows vista again with my backup cd, but i have not entered to it because Grub so i haven't done the first configuration to windows. After that i installed Ubunto 6.0.6 again but still i can't see my windows. Here are the data:

   Device Boot Start End Blocks Id System
/dev/sda1 2 6185 5120000 1c Hidden W95 FAT32 (LBA)
/dev/sda2 * 6185 71280 53898240 7 HPFS/NTFS
/dev/sda3 71404 117977 38563272 f W95 Ext'd (LBA)

/dev/sda6 71405 73877 2047638 82 Linux swap / Solaris

and this is my menu.lst

title Ubuntu, kernel 2.6.15-26-386
root (hd0,4)
kernel /boot/vmlinuz-2.6.15-26-386 root=/dev/sda5 ro quiet splash
initrd /boot/initrd.img-2.6.15-26-386
savedefault
boot

title Ubuntu, kernel 2.6.15-26-386 (recovery mode)
root (hd0,4)
kernel /boot/vmlinuz-2.6.15-26-386 root=/dev/sda5 ro single
initrd /boot/initrd.img-2.6.15-26-386
boot

title Ubuntu, memtest86+
root (hd0,4)
kernel /boot/memtest86+.bin
boot

With this information....Can someone help me enter to windows again...

Thanks!!!!

I've googling around and it seems grub does not automatically recognizes Vista yet, so it doesn't automatically make a menu-entry. But we can do this for ourselves:

Do a "sudo nano /boot/grub/menu.lst"
.. and add this to the end of the file...

  title Microsoft Windows Vista
  root (hd0,1)
  savedefault
  makeactive
  chainloader +1

I am guessing the (hd0,1) part, if that doesn't work you should try (hd0,0). But I think its the second-partition of the first-hard-disc ..so my guess is (hd0,1).

Remember to save the menu.lst (control+O and then press [enter])
Then you should try to reboot and test the setting.

Let us know if you succeed...

Did it work?
