Exclamation XP on internal drive wouldn't boot w/out Linux external one attached; now not at all


A few days ago I downloaded and burned the Ubuntu 9.10 live disk. I wanted to install it onto a portable external drive attached to my desktop so as not to mess with others who use the internal drive for XP. When I installed it I made sure the internal drive wasn't touched, and only used the blank external one. I made the external drive bootable with the disk utility, restarted everything and Grub was very cooperative in letting me pick an OS. But when i tried to start the computer without the external drive (to get into XP) because i want the linux drive to be portable, Grub tried to boot, said "Error: no such disk" and wouldn't access the internal C: drive top start up Windows. I googled for help, installed lilo (maybe not properly) on the portable drive, and when that didn't work installed grub on the C: drive. Now when i turn on the computer i get Grub saying it has a GEOM error and that i need to replace a disk. This happens in every case i could think of besides booting from the live Ubuntu CD. Can anyone help? I have some family members very mad at me about this.

Also, the external drive doesn't boot linux up when attached to other computers.

It sounds like you managed to install grub on the internal drive. All is not lost. You can either spend a bunch of time learning all about grub somewhere, or you can do the following: Download a copy of Super Grub Disk and install it on a CD as an image. Boot the machine from that CD and select the automatic option. It should be able to fix grub for you. I'm not sure whether it will automatically put an entry in for you for XP, but I'm betting it will.

Won't work if the external is broken. Better to get the machine booting from the internal.
Boot your XP install CD and select recovery centre when it says to. Run fixmbr and reboot.

You can then use the liveCD to check out the external.

i don't think the external is broken, because i can still access all the files from another computer; it just isn't booting.
i've tried downloading a super grub disk .iso, but whenever i go near a site with the download my internet slows down to nothing. any ideas?

What do you mean "near a site"? Here is a link to the download page on the official SGD site.

http://www.supergrubdisk.org/index.php?pid=5

This mirror from that page is, I believe, in the US. The other two are in Germany, so maybe that's the problem for you.
http://download.linux-live-cd.org/Su...ies/sgd/cdrom/

Added:
You probably want this file unless you either have Linux or want to download the bzip program first. It's only 3.9 MB which isn't a large file.

There's another question, though, are you sure that your BIOS is setup to boot from the internal drive? Did you change that when you were doing all the other stuff?

i got the download going fine, ran super grub and started a linux recovery something or other. i ran the fix errors option and updated the grub and now linux will boot up. i get a grub screen asking me to pick normal unubtu, a second ubuntu that's a backup or something, two memory check options, and windows XP. However, i can only choose the first ubuntu option, even though the others are recongized.

Let me make sure. Are you saying that you can or cannot boot XP from grub?


Original:
OK, at least this is something. Bring up a terminal in Ubuntu and let us see the results of the following:
Code:
cat /boot/grub/menu.lst
sudo fdisk -l
ls /dev/[hs]d*
What this will do is show me what SGD setup for booting to XP and what Ubuntu can see of your disks. After this, we'll probably try mounting your XP disk with something like this, depending on what drive XP is on.
Code:
mount -o ro /dev/sda1 /mnt

i pasted the code into the terminal and i got
cat: /boot/grub/menu.lst: No such file or directory
in response
i take it this isn't supposed to happen?

i ran it anyway; what part of the code do you want?

it can see all of my disks and partitions. Windows is on /dev/sda1, like in your example code so i ran
sudo mount -o ro /dev/sda1 /mnt
and the terminal said "the device or resource is busy"

Hmm. Please post the output of the other two commands as well as this:
Code:
ls /boot/grub
Maybe your grub uses a different name for menu.lst, perhaps grub.conf or something like that.

Wow, that's a lot of stuff in there compared to mine. So, let's see the contents of grub.cfg to see what SGD found. It should be a plain text file with configuration information in it.
Code:
cat /boot/grub/grub.cfg
Let's also see what Ubuntu has mounted, in case it's already mounted your XP filesystem for some reason:
Code:
df -h

installed grub on the C: drive.
the above from your initial post, big mistake. You've overwritten some of your xp boot files. When you try to boot xp now, what error message, if any, do you get? To repair the xp mbr you need an xp installation cd/dvd with a recovery option (or you can just enter R at a prompt) and run fixmbr and/or fixboot from there. Before doing this, disconnect the external so you get the right drive this time. If you don't have an xp CD, you can borrow one or download. I'd do a search here for repair xp mbr as I've seen lots of posts here at LQ where people had to repair the xp mbr.
