I am trying to replace the motherboard in my home pc, and I'm running into some booting issues. Probably due to being fairly new to linux.

On the origional board it was :
First drive primary channel, fat32 with fedora mbr
secondary channel, 2 dvd drives
first sata, data drive ext3
second sata, (hdg) fedora install
hdg1 /boot
hdg2 /
hdg3 SWAP
This worked without problems.

On the new motherboard :
First drive primary channel, fat32 with fedora mbr
secondary channel, 2 dvd drives
first sata, (sda) fedora install
sda1 /boot
sda2 /
sda3 SWAP
second sata, data drive.

Drives were just unplugged from one board and plugged into the new one.

On first boot I got
GRUB
I played with grub and now it loads the previous grub.conf, and I changed fstab to reflect the new drive location (I think).

However when I boot now I get
Booting 'Fedora Core (2.6.6-1.427smp)
root (hd1,0)
Filesystem type is ext2fs, partition type 0x83
kernel /vmlinuz-2.6.6-1.427smp ro root/dev/sda2 rhgb quiet

initrd /initrd-2.6.6-1.427smp.img
[Linux-initrd @ 0x37fad000, 0x4259f bytes]

Uncompressing Linux... Ok, booting the kernel.
ACPI S3 and PAE do not like each other for now, S3 disabled.
audit(1088139669.794:0) initialized

mount: error 6 mounting ext3
pivotroot: pivot_root(/sysroot,/sysroot/initrd) failed 2
umount /initrd/proc failed: 2
Kernel panic: No init found. Try passsing init= option to kernel.




My fstab is

LABEL=/dev/sda2 / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
. . .
/dev/hda1 /mnt/c auto defaults 0 0
/dev/sda3 swap swap defaults 0 0
. . .


my grub.conf

boot=/dev/sda1
defaults=0
timeout=10
splashimage=(hd1,0)/grub/splash.xpm.gz
title Fedora Core (2.6.6-1.427smp)
root (hd1,0)
kernel /vmlinuz-2.6.6-1.427smp ro root=/dev/sda2 rhgb quiet
initrd /initrd-2.6.6-1.427smp.img

I'd rather not reinstall if I can avoid it, but at the moment I'm stuck. So I thought I'd ask the best resource of linux people I know of.

/me falls to the floor groveling

Thanks
