Re: howto remove GRUB from the partition using fdisk ?
What you want to do ? If you remove grub from mbr you will not be able to boot your computer unless you have a bootdisk or using rescue mode from de installation CD.
waiting for more information.

Re: howto remove GRUB from the partition using fdisk ?
I use only NT-Bootloader from WIN2000 installed on the primary hard disk.
to boot linux and unix with NT-Bootloader I use bootpart:
http://www.winimage.com/bootpart.htm
this combination works very well !
my problem is to remove GRUB from the linux partition /dev/hdb5
and I'm not worried about booting.

Re: howto remove GRUB from the partition using fdisk ?
If you want to get uninstall grub from system
fist do a
#rpm -ql grub
just to see what is installed where
#rpm -e grub
!!! will erase it
This should do it , the quetion is do you realy need to do this grub does not use very many blocks... and if its not in the way why bother or have not understood this ?

Re: howto remove GRUB from the partition using fdisk ?
Is "hd5" also your root partition or do you have a separate "/boot"? If this is the case and you use a tool such as Partition Magic to delete the disk partition and reclaim the space, your partition numbering in "/etc/fstab" will then be wrong and the system will fail to boot. In this case you can:
(AFTER DELETING) boot into single-user using the installation CD-ROM and edit "/etc/fstab"
or
(BEFORE DELETING) edit "/etc/fstab" and move all your slices down one. E.g. "/ = /dev/hda6" becomes "/ = /dev/hda5".
This operation would be largely a waste of time unless you need to reclaim a partition to use elsewhere, as "/boot" is generally very small.

Re: howto remove GRUB from the partition using fdisk ?
can you post: [mod hd? to appropriate disk)
/sbin/fdisk -l /dev/hda
if grub is installed in the MBR, then
you need to replace the mbr with a suitable
alternate one: eg from XP: fdisk /mbr
[I don't know if this can be done from linux - although maybe its possible to use dd to write a suitable 512 bytes ???]
if grub is installed on a partition, then ...
i'm not sure!
dave.

"howto remove GRUB from the unix partition, without damage the partition (partition table) using linux fdisk ?"
He never mentioned the MBR so I assume he means remove a disk slice because he has grub installed in the root partition?
Chris can you please clarify this?

Re: howto remove GRUB from the partition using fdisk ?
Is it possible that you can talk us through your boot procedure/experience?
When you mention fdisk it makes me think that you have a specific slice that you want to remove?
