Messed up boot sector - dual boot linux 64bit and linux 32bit


I have right now two linux systems installed, both on the same disk in a three disk system. Mint13 32bit is on one partition and Mint17 64 bit on the other one. I had it booting from Mint13 and it was booting just fine into either 13 or 17, but mint 13 was first in line, so I decided to change it. instead of resetting the default in Grub, I ran grub-install from Mint 17 (the 64 bit system). Now it won't boot into either system from grub. It just gives me an error message - not from Grub, but from Bios, that there is no bootable device.

I can boot using Plop in the CD drive and choosing "boot from Hard disk". That takes me to the grub menu, and I can boot from there into either system.

I've tried running grub install from Mint13, but no good. So far I haven't been able to discover anyone with a similar problem, although I did run across one reference that seemed to indicate a problem using 32bit and 64bit systems on the sma3e machine, but there was no explanation.

That's a lame BIOS - you can usually fix that by ensuring you have the boot flag on one (and only one) of the primary partitions. Doesn't matter which, grub ignores it.

Thanks syg00
You may be right about the Bios, but:
I did check on the three disks that I have connected, and one USB thumb drive. The thumb Drive and /dev/sda were both marked with a 'boot' flag, so I turned it off on the thumb drive, and tried to boot without Plop. It didn't work. I still get a boot error from the Bios -didn't note the exact wording, but something like: "boot failure. Insert system disk..."

So I tried running "grub-install /dev/sda" and got a message that it had finished successfully with no errors.

But it still won't boot without Plop. Any tests that I can run on the Bios? Or ways to reset it? Or....?

Have you tried your backup boot blocks, should be a few spread out over your drive, just use dd to overwrite your boot sector with it.

So long since I've needed to do this that I can't remember how to find them, but no doubt, it will be on Google somewhere.

Please post the result of the Boot Info Script.
Boot your Mint DVD or USB.
Install boot-info-script:
Code:
sudo apt-get install boot-info-script
Then run the script:
Code:
sudo bootinfoscript
Post the results here - http://pastebin.com/ - and give us the resulting link.

I installed that script, and it apparently did install. The last ffew lines of the install procedure show:
Unpacking boot-info-script (from .../boot-info-script_0.60-1_all.deb) ...
Processing triggers for man-db ...
Setting up boot-info-script (0.60-1) ...


But the command:sudo bootinfoscript just shows:
sudo: bootinfoscript: command not found
+*+*+*+*+*+*+*+*+

Well a little snooping with mlocate and a look at my path tells me that boot-info-script is not in my path, so the command: /usr/sbin/boot_info_script brings it out of hiding. Here is "RESULTS.txt" (A Huge amount of info):

You ran "grub-install /dev/sda", but Mint 13 and 17 are on sdc.
I suspect that sdc is set to boot first in your BIOS. If you go into your BIOS and set it to boot sda first, and you should see the Grub menu.

If you want to boot sdc first, boot into Mint 17 and run the commands
Code:
sudo update-grub
Code:
sudo grub-install /dev/sdc
As syg00 said, you may have to set the boot flag on sdc1. Most modern BIOS's do not require the boot flag for linux, but your BIOS might.
Code:
sudo parted /dev/sdc set 1 boot on

I have run sudo update-grub /dev/sda and sudo update-grub /dev/sdb from mint 17, and when that didn't fix anything, I tried running it from mint 13.

Since a ran the script above, I have even installed an additional OS: RoboLinux 64bit. and I ran sudo update-grub /dev/sdd from there. Still no help. I am still booting with Ploplinux, but I don't know why that works but a normal boot will not.

Did you check your computer's BIOS to see which drive is set to boot first?

Yes I have. Bios is set to boot from /dev/sda . My understanding has been that with Linux it really doesn't matter. So I have also tried booting from both of the other drives, but that doesn't work either. Those two (/dev/sdb and /dev/sdd) also have grub recently installed on them.

I sought for directions to find and install the boot information from it's hidden locations on the drive, but didn't find it. I know that I have read that information before, but don't know how to find it or shat to call it.

I even tried installing another system so that it would write to the boot sector. It installed properly, and declared that there was no error when it wrote the boot sector. But it still will not boot without a boot disk in the DVD drive.

When you boot from plop which OS are you booting?
Did you unmount & remove plop after booting?

Just to clarify... It does matter. If your BIOS is set to boot from /dev/sda, then Grub has to be installed to /dev/sda.
You aren't trying to install Grub to a partition, are you? Like sda1?

Member response

Hi,

For Gnu/Linux the partition boot flag is of no real concern. If you are using 'MBR' then you would write the boot to the designated device boot sector and select either via BIOS or BIOS Boot menu via hot-key combination(s).
