CentOS - Dec 2011 - Booting C 6.0 from C 5.7

I installed C 6.0 in an empty partition. It functioned.

Despite using the usually successful methods of booting into another
operating system from C 5.7, I can't get into C 6.0

Tried:-

title C6-0 (2.6.32-71.el6.x86_64)

 	rootnoverify (hd0,6)
	chainloader +1

and

	root (hd0,6)
	kernel /boot/vmlinuz-2.6.32-71.el6.x86_64 ro
root=UUID=67c62872-0c69-451c-8412-3c218c0d2cb0 rd_NO_LUKS rd_NO_LVM
rd_NO_MD rd_NO_DM LANG=en_US.UTF-8 SYSFONT=latarcyrheb-sun16
KEYBOARDTYPE=pc KEYTABLE=uk
	initrd /boot/initramfs-2.6.32-71.el6.x86_64.img


My default works:-

title CentOS 5.7 #6 (2.6.18-274.7.1.el5)
	root (hd0,0)
	kernel /boot/vmlinuz-2.6.18-274.7.1.el5 ro root=LABEL=d6sys
ramdisk_size=600000
	initrd /boot/initrd-2.6.18-274.7.1.el5.img

and so does Ubuntu

title Ubuntu 11.04 (chain) (2.6.38-8)
 	rootnoverify (hd0,4)
	chainloader +1

but Centos 6.0 fails.

Advice appreciated.

What does it say when you attempt to boot to it? Did it fail on stage 1, 1.5 or
2?

The GRUB error is:-

13 : Invalid or unsupported executable format

This error is returned if the kernel image being loaded is not
recognized as Multiboot or one of the supported native formats (Linux
zImage or bzImage, FreeBSD, or NetBSD).


Bewildered.
