You need to clarify. Do you mean you want to replace Grub2 with Grub Legacy? Or do you want to make a usb/flash with Grub Legacy for a bootloader? For the second option, go to the site below, the section "to put Grub into a Partition". Gives a fairly detailed explanation. You will need to get the Grub Legacy files. I don't know if they are available in the Ubuntu repositories?

Fedora might have Grub Legacy. The last time I tested it there were Grub and Grub2 directories. If you boot the CD, look in either /usr/lib/grub or /lib/grub to see if they are there. You probably would be able to download Ubuntu Grub Legacy from their repositories/archives but I'm not sure. The Ubuntu forums would be a better source. Using 32 bit on 64 is OK, the reverse does not work. I would copy the Grub Legacy files to a /boot directory you create on the flash drive and then do the standard Grub Legacy installation commands.
