Loading Grub Fails

Hi, i have Ubuntu 8.04 installed on one partition and was looking at installing 64studio on another partition. The installation goes fine until it comes to installing Grub. Is recognizes that my Ubuntu 8.04 installation exists and then goes to install grub, but i then get an error message telling me 'unable to install grub this is a fatal error. Is it possible to run 64studio on a machine that already has grub installed, or do i need to do something to my Ubuntu installation to get this to work? kreeyon

Enjoy 64studio

Great news kreeyon, most times when grub fails like that, you loose grub, and can't boot into anything! Its always good to have a rescue 'livecd' close by, "Mepis" is good. Saved my skin many times. If you "had" lost grub..... and were unable to boot ubuntu. Install Mepis on the partition you were using for 64studio. This would confirm the partition was ok!. Takes 30min to install! Mepis grub would find ubuntu, creating a menu list. When you have ubuntu back, you would carry on just as you have. While you were busy I've checked out burning cd images using CLI. $ wodim --devices $ wodim dev=/dev/hdc driveropts=burnfree,noforcespeed fs=14M speed=4 -dao -eject -overburn -v yourCDimage.iso dave

Done it.

I checked the md5sum and that was fine re burnt the DVD at 4x but got the same problem when i got to grub, so decided to download a new copy from the website and that worked, so must of been an error caused during download. 64studio now up and running. thanks for the help.

You only need one copy of grub, it will boot all the operating systems you have. On your Ubuntu install, have a look at the /boot/grub/menu.lst. You will need to add an entry for your 64studio install. You may wish too look here for more info: http://grub.enbug.org/ Hth,

check md5sum

Hi kreeyon, Go back to where you downloaded the image from and download the .iso.md5sum file, make sure it's in the same folder as the image. 64studio_2.0_i386.iso. 64studio_2.0_i386.iso.md5sum in a terminal type: $ md5sum 64studio_2.0_i386.iso. which will display the md5 checksum of the file 64studio_2.0_i386.iso Then compare them against the official md5sums in the MD5SUM file from the mirror you downloaded from. google: check md5sum I find cd images are fine x8 but I burn dvd at x4. It looks like a bad image burn. 64studio_2.0_i386 has been installed here a number of times without any problems, and I multi boot. If you used the install disk to re-partiton your disk, and have only tried to install it once, it might be worth trying to install again. keep notes! If you have tried to install more than once already, give up on that disk. k3b should get your burn speed x4 and I think Brasero burner will get x4. You can apt-get both of these in ubuntu. If you have no joy download another image. Cheers, dave

Thanks for the reply

Thanks for the reply Dave. The image i burnt was 64studio_2.0_i386.iso I burnt the image using the standard write to disk option in Ubuntu 8.04 by right clicking on the file and burning to disk. This was burnt at the lowest speed the DVD could take which was 8x, not sure if the md5sum is OK, how do you check that? Once i get the grub error, the installation takes me to the screen that displays the list of install options, i then go down an option; passed the grub install option, where it says 'finish installation', but that takes me back to installing grub again. I can't seem to progress with the installation without trying to install grub first.

more info needed

Hi kreeyon, Which image are you using, 64studio_2.0_amd64, 64studio_2.0_i386, how did you burn the image, what speed, is the md5sum ok?. kreeyon> but i then get an error message telling me 'unable to install grub this is a fatal error What happens next? does the installer ask you if you wish to continue anyway? what did you do at this point? kreeyon> Is it possible to run 64studio on a machine that already has grub installed, Yes 64studio should take care of grub, You don't need to do anything with ubuntu. How did you partiton the disk? dave
