Some short explanation of what Live image you're trying to boot with and at 
least your partitioning scheme might help.

The GRUB error is indicative of GRUB not finding the partition in which the 
normal.mod module is stored.

Why not?  There should be no difference between a LiveCD and a LiveUSB.  If 
anything booting off a USB on some MoBos could be more troublesome.  Have you 
looked into this problem to find out if there was some MoBo setting you had to 
change (physical jumper/switch/cable, or firmware)?

Assuming this is a UEFI MoBo you can boot any kernel images on disk directly, 
as long as you can point the UEFI firmware to them.

Have a look here:
