Grub error 15

Hello,

I tried to copy my arch system to a new hdd. But something went wrong, with the new hard disk I get an error 15 from grub. And thats all.

To clone the system, I partioned the new hard disk and than booted with the arch live cd.
With "cp -a" I copied the old system to the new hard disk. I checked afterwards, that all files are there.
Than I startet grub and installed it to the MBR with root (hd1,2) and setup (hd1). The ouput says successfully.
Turned the system off and switched the SATA-ports on the mainboard. Reason is, that the new disk is now recognised as sda.
But a boot attempt leads only to the above mentioned error 15.

I could successfully install Windows 7 on the new disk and it started before I attempted to install grub. Also I can it start with grub from the old disk.
Old file system was ext3, on the new disk I formatted the linux partitions with ext4. The wiki says booting grub from an ext4-partition is not supported, but arch linux has a patch to do it inofficially. So that SHOULD not be a problem.

Any suggestions?

old disk:
fdisk -l /dev/sda

Re: Grub error 15

usually an error 15 is a problem with your grub configuration.
double check your menu.lst, and check that everything is correct.
if you cant see any issues with it, please post it so we can take a look at it.
