First Cup of Ubuntu
firstly, i apologize for my awful English...
I'm a begginer ubuntu user (better said, I'm trying to install it) and have got a similar problem...
I've acquired the ubuntu 9.10 CD in the ubuntu HP. My machine is a HP Pavillion DV6500 notebook, running with Windows Vista. I've tried to install ubuntu following the graphical install available in the ubuntu site. My option was to install it in a external HD, to avoid partitioning my primary HD. After the instalation was concluded, the notebook doesnt boot by the external HD, neiter by Windows anymore!! When I disconnect the external HD, appear a prompt with the following message:
no such disk
GRUB rescue>
The option to recovery Windows, supported by HP does not work anymore. So, I cant reinstall windows anymore, and my notebook has no boot!!!
please, could anyone help me???
Yours sincerely,
João Paulo

Let's get a better look at your setup & boot process. Boot the Ubuntu Live CD/USB. Choose "try ubuntu without any changes", when the desktop loads come back here and use the link in my signature to download the Boot Info Script to the desktop. Once on desktop open a terminal (Applications > Accessories > terminal) and run this commandThis will create a RESULTS.txt file on the desktop. Paste the entire contents of that file back here. Once pasted highlight all text and click the # sign on the toolbar to place code tags around the text.Code:sudo bash ~/Desktop/boot_info_script*.sh

dear presence 1960
i'm very glad about your help...
i've tryied the command and the response i've obtained was
sudo: /home/ubuntu/Desktop/boot_info_script*.sh: command not found
maybe my notebook does not have this command available (sorry about my dumbness)...

it seems to be that you entered the command improperly. try copying and pasting the command into terminal:
Code:sudo bash ~/Desktop/boot_info_script*.sh

Okay, I sorta have a similar problem. I don't know if the same fix will work so I'm just gonna tell you what it is. I had xubuntu on one partition and vista on another then I repartitioned some free space between the two of them and installed mythbuntu (using the "use the largest continuous space" option) so I could mess around with it without damaging my xubuntu data. I have everything pretty much backed up since I never repartition without backing up all data (Learned that lesson a long time ago). Everything is working fine and I'm booting up perfectly from all three os's. Now I don't want the mythbuntu anymore so I delete the partition (all files backed up, I'm a stickler for that). and then when I reboot my grub won't load and I'm dropped into the grub rescue prompt.
so I ran the boot info script and this is what I got

Well you see grub2 is looking for boot files on sda7 which no longer exists:
So boot any *buntu live CD and from the Live Desktop go to Terminal and:Grub 1.97 is installed in the MBR of /dev/sda and looks on the same drive in partition #7 for /boot/grub.
Code:sudo mount /dev/sda5 /mnt && sudo mount --bind /dev /mnt/dev && sudo mount --bind /proc /mnt/proc && sudo chroot /mntCode:grub-install /dev/sdaCode:exitThen reboot & the first time you boot into Xubuntu go to terminal and run:Code:sudo umount /mnt/dev && sudo umount /mnt/proc && sudo umount /mnt
Code:sudo update-grub

I only got this far.
I'm afraid to go any further and typeCode:To run a command as administrator (user "root"), use "sudo <command>". See "man sudo_root" for details. ubuntu@ubuntu:~$ sudo mount /dev/sda5/ /mnt && sudo mount -bind /dev /mnt/dev && sudo mount -bind /proc /mnt/proc && sudo chroot /mnt mount: invalid option -- 'b' Usage: mount -V : print version mount -h : print this help mount : list mounted filesystems mount -l : idem, including volume labels So far the informational part. Next the mounting. The command is `mount [-t fstype] something somewhere'. Details found in /etc/fstab may be omitted. mount -a [-t|-O] ... : mount all stuff from /etc/fstab mount device : mount device at the known place mount directory : mount known device here mount -t type dev dir : ordinary mount command Note that one does not really mount a device, one mounts a filesystem (of the given type) found on the device. One can also mount an already visible directory tree elsewhere: mount --bind olddir newdir or move a subtree: mount --move olddir newdir One can change the type of mount containing the directory dir: mount --make-shared dir mount --make-slave dir mount --make-private dir mount --make-unbindable dir One can change the type of all the mounts in a mount subtree containing the directory dir: mount --make-rshared dir mount --make-rslave dir mount --make-rprivate dir mount --make-runbindable dir A device can be given by name, say /dev/hda1 or /dev/cdrom, or by label, using -L label or by uuid, using -U uuid . Other options: [-nfFrsvw] [-o options] [-p passwdfd].

You got the command wrong.
Mine:
sudo mount /dev/sda5 /mnt && sudo mount –bind /dev /mnt/dev && sudo mount –bind /proc /mnt/proc && sudo chroot /mnt
Yours:
sudo mount /dev/sda5/ /mnt && sudo mount -bind /dev /mnt/dev && sudo mount -bind /proc /mnt/proc && sudo chroot /mnt
You also used some single- where they should be double --.
Do not try to type long commands just double-click within the code box, select copy, then paste them into the terminal.
So go back to post #27 and try again. If any part of that fails post back here.

BTW we're not trying to install to:
/dev/sda5
It's:
grub-install /dev/sda
Just copy-n-paste!
