GRUB trouble : I lost my GRUB!!!

[kauboy]

I installed Fedora Core 9.0 on my HDD containing Ubuntu 8.04 and WinXP, but on a different partiton. During the installation, I chose the Fedora Core's /boot partition as the install location for its Boot Loader, as I din't want it to overwrite the GRUB 1.5 of my Ubuntu from my MBR. Now, when I boot my system, I see "Loading GRUB 1.5 ....." for just one second, the same I used to see earlier during my Ubuntu 8.04 + WinXP times, but it doesn't load completely and instead, it loads the Fedora Core GRUB 0.97 or something. Here, I can only boot Fedora or Other (WinXP), I don't know how to get my GRUB 1.5 back!! I just want to get back to my Ubuntu!! Help please...

Try re-installing grub via the Ubuntu LiveCD, that should detect all your OS's for you.

How do I install the GRUB alone from the LiveCD?

Guess that's what the link was for! Sorry!!

Is there a way to get into Ubuntu without having to re-install my GRUB, because I'm quite sure that my old GRUB 1.5 is still present, just that it isn't loading. Then maybe, I can edit the menu.lst file in Ubuntu and get Fedora to load. I just want to load my Ubuntu GRUB 1.5, without re-installation if possible. GRUB 1.5 is still there, it just comes up for coupla seconds, then the Fedora GRUB loads up .

You have to reinstall Grub to the master boot record (MBR) and point it to your Ubuntu partition again if you want your Ubuntu's menu.lst to be used instead of Fedora's. Just do like Tatty recommended. Boot your Live CD, and do:

sudo grub
grub> find /boot/grub/stage1

If that returns two partitions in the form (hdX,Y), decide which is your Ubuntu partition and use it in the commands below. If it only gives one output in the form (hdX,Y), use that:

grub> root (hdX,Y)
grub> setup (hdX)
grub> quit

You can then add Fedora's menu.lst to your Ubuntu menu.lst with the following syntax:

title  Fedora
root   (hdX,Y)
configfile /boot/grub/menu.lst

Of course (hdX,Y) needs to be your Fedora partition, and you also need to make sure you give the correct path to the menu.lst or grub.conf, whichever Fedora uses. If you need help with that, let me know, otherwise let me know how it goes.

Im not really sure, im not sure how having multiple grubs works. Re-installing is just the easiest option as it should sort it all out for you.

If you really want to just fix it by hand then this page should help you.

It looks like Fedora's grub has installed to the mbr. You need to reinstall the ubuntu grub to the mbr using the live cd, as per the link. Only takes a couple of seconds so it's not a big job. Then you can edit menu.lst to add Fedora

edit: looks like we all replied at once

Evidently, I'm now running only Fedora Core 9.0 or something, as I've no means of loading my Ubuntu 8.04 yet.

Pardon me, 8 ) without the space in-between, is what shows up as 8) (without the space!!)
