i had installed the karmic koala on my portable hdd and installed the grub loader on the portable hdd. it was working fine until yesterday, but since yesterday when i boot up my laptop from the portable hdd,the grub screen shows and then everything goes black (the machine shuts down) if i select to log into ubuntu.it works fine if there i select and log into the windows option (installed on the laptop's hdd). is there a way to repair it?

if not, how can i retrieve my data from the portable hdd.i tried booting from the ubuntu cd and copying my stuff from the portable hdd to the laptop's hdd but it says that i cannot perform any file operations as im not the owner. how do i solve that problem?

any help would be greatly appreciated

The post #2 there has the explanation. You download the script, move it on desktop and execute it in terminal (Applications-Accessories) with the command given there.

I can't see anything there that I know is wrong. The only thing is here

sdb1: __________________________________________________ _______________________

File system: ext4
Boot sector type: Grub 2
Boot sector info: Grub 2 is installed in the boot sector of sdb1 and
looks at sector 1328775 of the same hard drive for
core.img, core.img is at this location on /dev/sdb and
looks on partition #1 for /boot/grub.
Operating System: Ubuntu 9.10
Boot files/dirs: /boot/grub/menu.lst /boot/grub/grub.cfg /etc/fstab
/boot/grub/core.imgThat looks like you have relics of a grub legacy as well as the grub 2 that the boot info script found. I don't know if this will cause problems, though.

There rest of it actually looks correct to me, but I am a long way from being good at reading the output to that script.

Just keep watching the thread. Now that you have posted the results.txt, I think you should get a response. If no-one has answered by tomorrow or so, just bump the thread (make a new post on the thread. Most people just write a post with "bump" in it)

You might want to add code tags around that output to make it easier to read. If you select "edit" in the post, then click on "go advanced" at the bottom of the edit window that opens. Select all of the text from the results.txt file, then click on the # symbol at the top of the window.

Sorry I can't help more than that.
