chain load failure using CentOS 6.3 grub

Just to report a problem thatI manage to avoid when I put Linux Mint 14 and CentOS 6.4
on my new Lenovo Y480 computer.

On /dev/sda1 I installed a base OS CentOS 6.3 system. I edit
/dev/sda1/boot/grub/grub.conf to either boot directly other new linux distros or
to chainload a new OS on other partitions.

Usually chainload always work on my other old computer.

On my new Lenovo computer,
I installed Linux Mint 14 on another partition and it is strange that

an entry such as

root (hd0,6)
chainloader +1

does not work and I hit a problem something like

Error 13: Invalid or unsuppored executable format
Press any key to continue...

Similarly I installed CentOS 6.4 last night and the chailoader trick give me

"Error 18: Selected cyclinder exceeds maximum supported by BIOs.
Press any key to continue"

On both occasions I was not despair since I had
learned a trick to copy vmlinuz and initrd file
to /dev/sda1/boot

and then create new entries in /dev/sda1/boot/grub/grub.conf
accordingly that looks like

root (hd0,0)
kernel /vmlinuz-2.6.18-164.15.1.el5 ro root=/dev/sda3 rhgb quiet
initrd /initrd-2.6.18-164.15.1.el5.img

so that direct booting is enable. I "solved" the BIOS errors by
"avoiding a problem" but I thought I should report and share with other what
might have happened.

Thanks for posting your success. It helps us to learn and be aware of possible surprises-

Bet Linux Mint looks great on you Lenovo!

In regard to this error:
Error 13: Invalid or unsuppored executable format
Is this error associated with a device or a partition?
Please explain.
