debian squeeze on hp dv7 4129wm

Hi,

Has any one been successful in installing and booting up a debian squeeze with a hp dv7 4169wm with an external usb drive - seagate 1.5T goflex ? I was able to install the os ok but it always bootup to grub-rescue prompt and it complains about not able to see the UUID of the external disk. Doing a ls shows only my first sda drive with windows 7 and ubuntu wubi on it ....

It sounds like a problem with the device map when grub was installed. You can reinstall grub from rescue mode, and rerun grub-mkdevicemap manually. I wrote my own guide for this but the Ubuntu wiki is just as good: https://help.ubuntu.com/community/Grub2#Reinstalling from LiveCD

See the method for chroot.

 

Thanks for replying. I had an internal 750G sata drive with dual boot windows 7 and a wubi installed ubuntu maverick 10.10 booting just fine then when i installed an external usb 3.0 1.5TB seagate drive with debian squeeze 6.0 and that is when I saw the problem. I used the default partion tables the installation CD came up with and allowed it to install grub at the end of the install. I tried the different methods that was described in the document however I keep getting permission errors no matter what I did. I used the following chroot command to see if the permission errors go away but it didn't work:

sudo chroot /media/6982a57d-61ae-4378-b3d1-98da9f5fd3e7 /bin/bash

Here is the output:

I'm not seeing the permissions errors you are talking about. It looks like you know that you need to be root (or use sudo) to do these commands so I'm a bit confused as to where you would be getting the permissions errors.

What I said earlier I still think is the fix, re-run the grub-mkdevicemap and re-install grub.
