GRUB bootloder or lack there of?

Postby 0dbm on Fri Jan 09, 2009 10:10 am

I've tried twice now: I have a shuttle computer with a 640GB HD. Primary partition fills up all but 10GB which is the space I allotted for MINT. I have tried three times now, deleting the partition and reinstalling mint via the option "guided - use largest free space" and it installs fine (hangs on installing language packs but I just skip that step)

on reboot windows XP boots up, grub never shows its face. previous Ubuntu installs have not had this error. is there something obvious I'm missing?

Linux Mint is funded by ads and donations.

Are you sure you just skipped language (I know - there is a Skip button :)) because grub is the last thing to be installed
As far as I know there is no limit to where you can install Linux, but to install it in 630 to 640 GB may be too far into the drive
It's hell too google this up :(
Hope to have an answer about this soon

It should work I think but it is a very bad solution not to put your operating system in the beginning of the hard disk
Very first the swap partition then the root partition
And if you litterally fill your hard disk completely I think you may run into problems

I have a thought. Since you can obviously boot the Mint live CD, do so, then go to Terminal and run each of the following commands:

Code: Select all
sudo grub


That will set Terminal to grub mode, so instead of seeing the normal: "yourname@yourname-desktop" you'll see the prompt: "grub>".

Then run the command:

Code: Select all
find /boot/grub/stage1


I'd almost expect to see an error or errors here. If so then I'll want to know exactly what error(s) show up. And if there are errors then run:

Code: Select all
quit


Which will drop you back to "yourname@yourname-desktop".

Then I'd like you to run:

Code: Select all
sudo fdisk -l


NOTE: That's a lower case L, not a one!

And also copy-n-paste that output here.

If on the other hand, when you run "find /boot/grub/stage1", you get an output something like:

(hd0,1)


Then instead of typing "quit", go ahead and enter (following the "grub>" prompt):

Code: Select all
root (hd0,1)


NOTE: You would of course use the numbers that "find /boot/grub/stage1" produced! In my example "/boot/grub/stage1" is on Hard Drive #1, partition #2.

Then run (again following the "grub>" prompt):

Code: Select all
setup (hd0)


NOTE: That is a zero - indicating Hard Drive #1.

And then finally:

Code: Select all
quit


Have I completely confused you? If so ask for clarification before proceeding!

Another option would be trying Super Grub Disk:

Sorry for the absence there, I got around to doing what you said, step by step and after doing the first grub command I received an Error 15: file not found

this is the output from fdisk:

Im going to check out the grub disk link but Im curious where to go from here terminal wise
