hi i want to uninstall grub so i can use windows normally (Have linux(dont working) on a external disk)...

How can i uninstall Grub? I tryed google but i dont have a windows xp install CD... But i have knoppix if that can help me to delete grub

Thx!

Uninstalling grub isn't enough, you need to reinstall windows bootloader, for which you need an install or repair disk

Can somone give me a link to a windows bootloader-repardisk iso image?

Not exactly an iso image, I suspect it's illegal to distribute such iso images, this however is a article from MS to describe how to fix the mbr

http://support.microsoft.com/?scid=kb;en-us;314503

from the boot disk, run:

fdisk /mbr

this will get rid of the linux bootloader and reinstall the windows one

you can always get a boot disk from www.bootdisk.com

i recommend the windows 98 se boot disk, it has all you need

the rabbit hole gets deeper if you ask this question
some user has 2 windows partitions installed and a linux
if he makes C:\format /MBR
wich windows will boot up next time he reboots ?

HELP
I dont have floppy in my laptop
but i have cd burner

that should be answered by the windows boot.ini file.

and it's NOT c:\format /MBR

you need to boot to a bootdisk and run fdisk /mbr

then put in the windows xp disk and boot to the recovery section and do fdisk /mbr or fixmbr

For a laptop user without access to a floppy drive and no installation Windows CD then follow this bomb-proof route

(1) Download "FreeDos" boot CD image
(2) Burn it into a CD
(3) Boot up FreeDos CD and use its fdisk.exe inside and type
FreeDos is also embedded in "Ultimate Boot CD". Google any of the two as there are many sites that host the iso images for free download.

I dont have a floppy, but i can do it from knoppix i think i have "Knoppix hacks"

Yayd,

Please be realistic.

You need a MS's MBR to boot a Windows and that is not supplied by Linux because Linux's own boot loader like Grub can boot over 100 systems including any number of Windows you throw at it.

Why would a Linux have a need for a Windows MBR?

Normally you can use Grub to boot your Windows as quick as you want. Since you didn't realise that not all Linux are installable into an external hard drive and so you may not have a partition to host Grub. Therefore Grub may not be working in your PC.

The bomb-proof route of my previous post is a good bet.

If i format my external harddrive, i only get error and cannot boot to windows, so i need to have the external harddrive plugged in to boot windows. And i use this laptop at school...

The MBR should be the one in the internal hard disk, not the external one.

You should never need an external disk to boot a Windows. Never heard of such a thing.

Windows, like Linux, cannot be booted from an external had disk. Only a small number of specialised Linux have been designed to boot from an external hard disk.

When you fix the MBR it is always to fix the first bootable disk.
