[ubuntu] Boot grub legacy from grub2?

view story

http://ubuntuforums.org – I have an old hard disk drive (the ribbon one) that I see using usb has a boot partition but don't see anything else. So, I thought to try to boot up the the disk (which is running legacy grub) over usb from grub2 to check it out. But, google has failed me. I can find the drive fine, I think. Code: grub> ls (hd1,1) Partition hd1,1: Filesystem type ext2 - Label "/boot" blah blah blah grub> set root=(hd1,1) grub> chainloader +1 error: invalid signature grub> NOOOOOOOOOOOOOO! I want to see the data on that disk. Is there a way to boot it? (Hardware)
