Fixed the old HDD so that is booting OK now.
but I'm still having problems getting the new HDD to work.

I'm trying to "setup" the new HDD without using a rescue disk.
I sure am doing something wrong or am missing some part of making it bootable.
One time I tried to boot from it, it said something about my /dev/sdb3/ and that is the new "swap" drive, but that can't make it unbootable I think.

so... I still need help and lots of it

If you have changed not only the size of the partitions (in comparison to your old setup) but also the order of the partitions, you also have to adapt the /etc/fstab file of the new system, especially when your system is now on /dev/sdb instead of /dev/sda.
I personally would recommend to remove the dying disk and fix your new install from a live-CD, that should be much easier and will prevent later trouble, when you have to remove the dying disk anyways.
So please, remove the old disk, boot from a live-CD and post the output ofand the contents of your /etc/fstab and /boot/grub/menu.lst, of course from the new system.

I'll do that, but...
If I copy all files from the old disk's partitions to the new and then try to install the grub boot on it, that should work, right?


I've copied all partitions, the '/' and the '/data' is the most important partitions
well... the '/' too or else I need to reinstall the system
and after this try to 'grub-install' that SHOULD make the disk bootable and a copy of the old one, right?

As long as you remove the old disk before the grub-install that should work, yes.

so I have to remove it... hmmm
thought I could do it on the fly
k... I'll try that

oh, but I have to start it with in "rescue" right?
and chroot the /mnt/sysimage and THEN do the grub-install?

You don't need to chroot, just mount your new system (don't forget the boot partition) and then use the --root-directory option. In your case, after removing the old disk and starting from a live-CD it should look somewhat like this:

Tried this 5 times now and after the /mnt/boot doesn't seem to exist.

so in the latest "try" I tried to but then all of a sudden no directories existed at all.


so again(getting more and more confused...) by your latest post...
you mean, after have booted on the original drive and copied all files from the original partition to the new disk's partitions...
Then I remove the old HDD and with a the "full" Fedora 12 DVD and using 'rescue' mode... get "into" the prompt and then do the
mountings as you say?
If I mount /dev/sda2 /mnt ... then not one directory exist at all.
seems to me like a bad disk or something, but the disk when checked is OK.
If I 'umount' I still get the same, like no directory exists.


I'm off this for tonight, but any clues for this will help...

According to your previous posts the second primary partition, which should be /dev/sda2 when no other disk is in the system, is the /-partition of your new system.
When after trying to mount it withthere are no files in /mnt that can only mean that either the mount failed (got any error messages?) or you didn't copy the files.

There was some error of some sort on the new disk so I recopied all and then the it worked... well the mount anyways

If I now just have the NEW drive attached then the thing you said before:
That must be ALL /dev/sdax you mean right? since that's the only HDD device in /dev/
If mounted these in /mnt/1/ and /mnt/1/boot/
If I do that then I get this:

What is not found cos 'grub' is there

and if I chroot into sysimage and try grub-install
then I get this error:
and the text is cut off yes

Try this:Then reboot, and it should work

First I guess you meant mnt for all mount
I tried that but I still get the same error:

oh and is it /dev/sda or /dev/sda1 I should use for installing grub?
I tried both though

It should be /dev/sda for installing grub.
Please do the mounts, chroot into the new system and post the output of

I got them all in there...
