Changed hard drive now system will not boot [Solved]

Hi,

Right got myself into a real mess, transferred data from old drive to new ... set up fstab ... grub is working...

But.... getting init kernel panic

Now I figure I need to reinstall kernel [via chroot! in wiki!]

first try did not work via ubuntu live cd so am burning arch disc now

I noticed that /dev is empty wondered is that would cause a problem

reallly do not want to install Ubuntu as I need my box hehe

While most things in /dev are created on the fly you do need a console node and a null node to boot the system.  If you boot a cd, mount the drive (eg /mnt/disk) and then

mknod -m 600 /mnt/disk/dev/console c 5 1
mknod -m 666 /mnt/disk/dev/null c 1 3

That might fix the problem.

The other times I've had kernel panics have been when the root=/dev/sda? bit of the kernel line in grub was pointing to the wrong place (kernel was looking at my /home partition and wondering why it couldn't find init) so thats another thing I would check.

thanks for that :-) I knew /dev /proc etc... as you do not need to copy them over so yes it may be the problem.... I changed grub I knew I had to change root [although I still forgot when I first booted ;-( ]

I have burned an Arch install disc now, was using Ubuntu livecd to chroot in but it takes forever to load lol... been a while since I transferred a drive

really do not want to reinstall

I am assuming that /proc /sys /tmp of course need to be empty...would be nice to get new drive working
