Boot Z20t from USB

I cant get my Tochiba Z20t to boot from USB.

1. Check USB is bootable  (See below)
2. Check Bios set to boot   F2 menu
3. Disable Secure boot - (F2 Menu) done
4. Force Boot from USB (F12 Menu)

Does not work.
I have a Win 8 USB, A Linux "Ulimate Boot CD" USB
None work?

 

1 This shows MBR which I understand means it is bootable

 

 

 

#3 Disable Secure Boot

 

 

 

READ HARD DRIVE HARDWARE SERIAL NUMBER
What I would really like to do is write the serial number so I can maintain activations of pre bought and installed software.

To READ the hardware serial number:
Open a CMD prompt.
Type wmic diskdrive get model,name,serialnumber
