Apologies if anyone else has posted this, I didn't find it when searching the forums. Boot a live cd, I used a PCLOS '07 disc I had handy. Click My Computer, System, your root partition. Root directory/desktop/repair mbr link on desktop. Run it, close/save the conf. file it shows, reboot.
It worked for me anyway, I could find my ubcd and didn't want to download it again..

Hmm, Start > System > Configuration > Boot and init > Redo MBR is on the Live CD (PCLinuxOS) but I guess your solution would become handy when using a other distro's Live CD .... Will keep and try this tip, thx.

Grub native install:
From a root terminal on any live CD from any distribution that uses grub; not grub2.
[root@localhost ~]# grub <Enter>
grub> find /boot/grub/stage2 <Enter>
(hd0,0) <-- Yours will vary depending on where Linux is installed. Use your results for next command.
grub> root (hd0,0) <Enter>
Filesystem type is ext2fs, partition type 0x83
grub> setup (hd0) <Enter>
Checking if "/boot/grub/stage1" exists... yes
Checking if "/boot/grub/stage2" exists... yes
Checking if "/boot/grub/e2fs_stage1_5" exists... yes
Running "embed /boot/grub/e2fs_stage1_5 (hd0)"... 15 sectors are embedded.
succeeded
Running "install /boot/grub/stage1 (hd0) (hd0)1+15 p (hd0,0)/boot/grub/stage2 /boot/grub/menu.lst"... succeeded
Done.
grub> quit < Enter>
[root@localhost ~]#

I feel like writing that on the wall OP ! One never knows .. It's simple enough to memorize. Lord knows I did.  You can find it here too, if you can boot the liveCD and get on the net.  |

If you run linux from within an extended partition then repairing the mbr is not enough.You may need to fix the extended partion as well which is the first 63 sectors of any logical partition.I would strongly recommend backing up your mbr and all the extended partions on a hard drive.This is simply done with sfdisk :
sfdisk -d /dev/hda > hdd_partions.save
This will save the mbr and all the extended partions into a file named hdd_partions.save (you can name this whatever you want).Remember to put the saved file onto a removable media because if the partion table gets hosed you won't have access to your OS!Replace /dev/hda with whatever hdd the OS is on.If the mbr or extended partions get messed up you can restore it with:
sfdisk /dev/hda < hdd_partions.save
