Centos installing grub problems suspect gpt problem

grub> root (hd0,0)
root (hd0,0)
Filesystem type is ext2fs, partition type 0xfd
grub> setup (hd0)
setup (hd0)

But if you do:
root (hd1,0)
setup (hd1)

it does work, I think hd0/sda had a GPT partition that was not removed properly (what I did was just dd bs=512 count=1 the partition table from another drive since the partition table should be identical).

Checking if "/boot/grub/stage1" exists... no
Checking if "/grub/stage1" exists... yes
Checking if "/grub/stage2" exists... yes
Checking if "/grub/e2fs_stage1_5" exists... yes
Running "embed /grub/e2fs_stage1_5 (hd1)"... 27 sectors are embedded.
succeeded
Running "install /grub/stage1 (hd1) (hd1)1+27 p (hd1,0)/grub/stage2 /grub/grub.conf"... succeeded
Done.

Converted 3 partitions. Finalize and exit? (Y/N): y
Warning: The kernel is still using the old partition table.
The new table will be used at the next reboot.
GPT data structures destroyed! You may now partition the disk using fdisk or
other utilities.

===========
I can even do
root (hd1,0)
setup (hd0) and it will work.........but not hd0,0 even though both are in the same RAID array on the same partition
