If boot from grub on internal is really required then a small boot partition will do the job ... but my previous post should be more straight forward ... (assuming boot from external is supported by BIOS).

Hiya, Jonathan!

Well, I'll admit when I'm wrong

Oddly enough, though, this method has worked for me before. But you know as well as I, YMMV!

Kaistar, have you tried the method Jonathan pitched out? Exactly as he described?

Haha I have a few more questions for him before I try it. Still awaiting his reply. Thanks for the help though Jay lol. Dang I was so sure I can move on to my next worry...

Questions regarding the details of his process? Which part is getting you?

Also, could you perhaps explain how to install the Grub into the External HDD? Which step of the installation etc?

You can try Windows CD but many report it does not work ...

Supergrub is my recommended method to fix the issue (you can put it on a pendrive as well) ... if you want to you can use the dd command to wipe the grub code from the MBR - but type very carfully or you can wipe the whole hard disk and even the wrong hard disk

Code:

dd if=/dev/zero of=/dev/sda bs=446 count=1

Installing grub to the external ... boot from a live CD and install grub by opening a terminal and executing the commands I gave in post #14. You don't need to run through the install process again

Those are my questions lol.

I think I have answered the questions ... but the steps in post #14 ...
sudo grub <- start grub with root rights
root (hd2,4) <- select (hd2,4) = sdc5 as the root
setup (hd2) <- install grub to (hd2) = sdc MBR
quit <- quit grub

you can check the info in the grub manual here ... and dd command info here

Ed: and this may also be useful ...

Hi! Back! I fixed my boot with the XP disc. Am now in Ubuntu Live CD but I can't do the "root (hd2,4)"

It says Selected Disk Does Not Exist

**Jonathan183** · 05-03-2009

OK ... glad the XP disc cured the internal drive boot issue.

Boot from a live CD with the USB drive connected, open a terminal and run

Code:

sudo grub
find /boot/grub/menu.lst

Ed: lets say you get (hd2,3) returned by find then you would do

Code:

root (hd2,3)
setup (hd2)

then

Code:

quit

It says file not found?

**Jonathan183** · 05-03-2009

hmm ... double check connections on the external drive, external drive power supply (if it has one) and re-run

Code:

sudo fdisk -l

command ... what is reported?

Ed: and try

Code:

sudo grub
find /boot/grub/grub.conf

what is reported?
