Hi everyone!
I have got a very strange boot problem.
But first: I have openSUSE 11.4 with kde installed.
I have the amd64 dual core cpu and 2 hard disks.
I was able to boot from both of those disks (on the second disk I
have openSUSE 11.2 in case something goes wrong with the
first disk).
Then I decided to install openSUSE 11.4 from DVD to a usb key (just like
I would to a hard disk). I succeeded. I did not involve any partition of the
hard disks in this install.
But now I can not boot anymore from any of my both hard disks although
bios finds them it did before.
After bios I get the following message:
Loading stage 1.5
error 21.
Error 21 means: Selected disk does not exist
This error is returned if the device part of a device- or full
file name refers to a disk or BIOS device that is not present or
not recognized by the BIOS in the system.
But I am still able to boot from usb key. I have even modified the menu.lst
from the usb key to boot openSUSE 11.4 from the first hard disk. This works
fine. I have also tried to install grub again on my first hard disk with
grub.install.unsupported and with yast2. But installation stops with an
error message like “hard disk not found by bios”.
Has anybody some idea.
Thanks for your help.
It sounds like to me you have installed the Grub Boot loader on the internal hard drives which is pointing to a menu on the USB key drive. Anytime you install openSUSE on a drive that is not the normal boot drive, you must go into the booting section and determine if and where you are loading grub. It can be placed into the MBR (Master Boot Record) or into one of the first four primary partitions, on any disk. When installing to an external USB key, it does not sound like you pointed grub to be installed there. urther, if this disk was to be stand alnoe, your BIOS would need to be direct to boot from the USB key. So, you will need to learn how to reinstall grub in order to fix your internal drives to work without the usb thumb drive being installed. There is a script file called findgrub, which when run can find all boot loaders and provide enough info to help fix the problem. Findgrub 3.3 is the most recent version you can find here:
Looking for Grub and Windows bootloader in all partitions. - Page 11
Normally you copy the text from the code block into a text editor like kwrite and save the file into your /home area bin folder as findgrub (~/bin/findgrub or /home/username/bin/findgrub). Then, it must be marked executable. Run the following terminal command to make that happen:
chmod +x ~/bin/findgrub
To use findgrub, open up another terminal session and type in the command:
findgrub
Then copy and paste the text output from findgrub into a code (#) block using the adanced message editor. This will help us see what has went wrong.
Thank You,
Thank you for your answer.
I’m not at home right now, but I will execute the script as soon as I am at home and post the answer tomorrow.
Anyway I am sure, that the bootloader was correctly installed on the usb key. I can boot this usb key on any
computer I have tried so far.
I thought that maybe my bios got somehow damaged, because grub replies with error 21.
Again, thanks for your answer, I will try the script.
I’ve run findgrub with different options on my computer.
Here are the results:

My primary hard disk is /dev/sda. It has only one boot partition.
My secondary hard disk is /dev/sdb. It has 2 boot partitions.
The usb key /dev/sdc1 is the only that I am booting openSUSE 11.4 from the first partition from
the first hard disk /dev/sda1 . In Grub syntax it is (hd0,0).
Finally /dev/sdd is just another usb key that I use only for data. It has no operating system or boot loader installed.
I hope anyone can see something in this and can help me.
