I am not using EFI/UEFI. I have a functional YUMI - a bootable usb. I cant boot directly to usb on my neighbor laptop. The laptop has EFI/UEFI features but it is disabled. Currently my partitions are:
sda1 fedora20 /boot (ext4)
sda2 fedora20 / (ext4)
sda3 windows7 (ntfs)
sda4 data (ntfs)
I wanted to add a menu entry to fedora20 grub2 so that i could boot my usb through fedora20 grub2. It is like plug my bootable usb -> power on -> fedora menu shows then i select yumi boot to usb -> then yumi menu shows -> then select systemrescuecd (something like that).
