Clone via DD OpenSUSE not working

I cloned a Virtual machine hard drive by hooking up an external hard drive and booting the source machine from Live CD. After doing
dd if=/dev/sda of=/dev/sdb

Open in new window

everything looks to be exact.

When inserting the new drive into a physical server, it boots up, gets to the GRUB, and asks me what kernel to select. I allow it to use the first kernel and proceed. It never boots and shows the following screen:

So we immediately changed the two files below:

device.map:
from:
(hd0)      /dev/disk/by-id/ata-VBOX_HARDDISK_VBaa736b17-5f8d9b0e
to:
(hd0)      /dev/sda

and

menu.lst:
from:
    root (hd0,0)
    kernel /vmlinuz-2.6.37.6-0.11-desktop root=/dev/disk/by-label/root resume=/dev/disk/by-id/ata-VBOX_HARDDISK_VBaa736b17-5f8d9b0e-part3 splash=silent quiet showopts vga=0x317
    initrd /initrd-2.6.37.6-0.11-desktop
to:
    root (hd0,0)
    kernel /vmlinuz-2.6.37.6-0.11-desktop root=/dev/sda vga=0x317
    initrd /initrd-2.6.37.6-0.11-desktop



Still, it does the same thing from above. I am clueless. Is this something to do with a "resume" file that is not listed in the above two files that we edited? Thanks for looking.

Did you also change the entries in the fstab file, or did you forget that?
