Titel: Grub error after install

Hi
Hope someone can help a klutz like me. Have just completed an install on my PC, but grub shows this when I boot my system:

GRUB Loading stage 1.5.

GRUB loading, please wait...
Error 21

I am a complete idiot when it comes to anything like this. I have had a look here in the forum for any answers, but have not found anything. Please if anyone can help i need every tiny step explained to me.

Thanks in advance

How old is your computer? Please boot it off the LiveCD and post the output of the following shell commands:

Code:

lspci

sudo fdisk -l

This error comes only if GRUB cannot load. Did you have any Linux distributions before? Did you put GRUB into MBR when installing or was it the ROOT partition?

grub error 21 means that the disk referred to in /boot/grub/menu.lst is not present. There are three possible causes for this error:
1. Your computer's BIOS doesn't handle drives > 80 GB correctly, so grub cannot read the boot configuration files that are located in /boot/grub on partition hdb5. Suggested fix: A BIOS update might solve the problem. Alternatively, you could try to install Kanotix on partition hdb1 to move the boot configuration files to the very beginning of the hard drive.
2. You rearranged drive setup after installing Kanotix by adding, removing or switching drives. Possible fix: Restore initial drive configuration or reinstall Kanotix.
3. Something went wrong during the installation. Possible fix: Check KanotixCD for errors with cheat code testcd, then install again.

Hi hey_ian
Yes I did have a linux distro before......Red Hat 9. I put Grub into MBR

Does this help?

Hi ockham23

1. Could be the bios as you said.
2. Have not moved anything since install as can't boot anything.
3. Will check CD now and come back to you.

Sorry, but where do I check out the CD from? Is this in Konsole again?

Thanks

Append testcd to the line of boot commands at the bottom of the boot screen that has the 30 seconds countdown on it.

If the GRUB error remains I recommend you to test LILO

Back again.

Grub says that testcd is not a recognised command and gives me an error 27

Any other ideas?

Boot from LiveCD and change this line

Code:

ramdisk_size=100000 init=/etc/init lang=us-utf8 apm=power-off nomce quiet acpi=off nodma vga=791 splash

Code:

ramdisk_size=100000 init=/etc/init lang=us-utf8 apm=power-off nomce quiet acpi=off nodma vga=791 splash testcd

This is just an example where to append testcd. Take the line that you see when you boot off the LiveCD and add testcd to it.

Sorry about that, I don't try to be thick it just comes naturally.

Right have done that and CD checks out OK

Just thought you might like an update. I've tried doing another install an I still get the same "Error 21" message so I think it must be a bios problem. So I guess I'll just stick with the live disk for now as I'm hoping to upgrade my computer in a couple of weeks.

I would like to take this opportunity to thank you all for your help, though. I really appreciate it. Smilie
