I need to study "grub2" in more detail!
Lots of basic commands and shortcuts have changed.
One major difference is the support for GUID-based partitions
(remove the familiar DOS-partition limitations, including, 
crucially now, the 2TB disk limit; but also improve reliability
of describing the intended device, and allow lots of partitions).

----

The old "kernel" command (load a kernel) is now "linux" or other type.
One can load grub modules for various support.

One handy feature is mounting an image-file on a loopback 
device within grub, to access its files: here's an example, 
plagiarised, for Linux-Mint(KDE)-12. 

grub2 

        loopback loop (hd0,msdos1)/dl/mint-12-kde-32bit.iso
        linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=/dl/mint-12-kde-32bit.iso noeject noprompt --
        initrd (loop)/casper/initrd.lz
