[SOLVED] Boot problems

[MikeTbob]

Try

sudo /usr/sbin/grub

I'm thinking Grub did not install correctly for some reason.

I ran the following command, gksudo gedit /etc/default/grub and got this output.....

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.

GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet"
GRUB_CMDLINE_LINUX=""

# Uncomment to enable BadRAM filtering, modify to suit your needs
# This works with Linux (no patch required) and with any kernel that obtains
# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)
#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xe fefefef"

# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console

#GRUB_GFXMODE=640x480

#GRUB_DISABLE_LINUX_UUID=true

# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_LINUX_RECOVERY="true"

# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"

Does this help or am I moving in the wrong direction?

Running sudo /usr/sbin/grub gives the same error.

I agree with you mate, it doesn't look like grub is where it is supposed to be.

Something that I just remembered, when i rebooted the computer last night I got the following error:

error : no such device : 6d4ff91c-1db8-4d46-9ca4-83967b03b235

Oh yea, and below the error was the "grub rescue >" and the only thing that I could enter was ls -l, when I entered that command I did see a list of devices attached to the computer, i.e., (hd0,1) (hd1) etc. I don't remember all of the devices that were listed.
Does this help at all?

And you are running these commands from a LiveCD?

I think the easiest way to set this up is ...
1. configure BIOS to boot from sdc first
and either
a) chroot into the Mint installed on sdc5 and run sudo update-grub && sudo grub-install /dev/sdc
or
b) re-install Mint and allow it to install bootloader to /dev/sdc

Yes. I am using the Linux Mint 10 64 bit distro. Live DVD.
Is it possible that I have a corrupted copy, corrupted meaning that grub is corrupted?
I never did check the MD5 hash. I have never had a problem with any of my downloads in the past.

You should be able to check md5sum ... and I think one of the boot options is to check the dvd integrity. It is a quick check worth doing.

@Jonathan183.
I am not quite sure how to set up the BIOS to boot from the sdc device first except, to hit F-12 during the POST process. Is this what you are talking about here?
By pressing F-12 during POST I am able to select which device I want to boot from so I assume that this is what you are referring to. (Please forgive my ignorance)

Assuming this to be the case I will give this a try.

I will check the MD5 sum first.

@Jonathan183
Well my friend, your suggestion worked! At least as far as I have gone through the steps.
I followed your initial suggestion to, 1. configure BIOS to boot from sdc first.
Following this procedure I was able to boot into Linux Mint located on /dev/sdc.

I apologize that I don't know that much about Linux commands yet but I am not exactly sure how to chroot into the Mint installed on sdc5. The rest ot the command I know how to do (sudo update-grub && sudo grub-install /dev/sdc)

Is the chroot command like the cd command? Except of course, you are changing to a specific directory and bringing root privileges with you? If so, then I think I know how to do it.

We've been successful so far, I don't want to mess something up at this point by executing a command that I'm not familiar with.
