BIOS Virualization problem (UEFI vs Legacy)

[SilentOne007]

So i cant run some applications on my computer because my Virtualization is disabled and Hyper-V is supported, but as i go into the Bios setup i cannot find VT so i change from legacy (Default) to UEFI so i can enter UEFI setup from my settings but when i save changes (On UEFI) and try to start my computer it says "No bootable device- please restart". Nothing is working and i changed back to legacy so i can use my computer a little bit atleast but there is no UEFI Setting then ;( What do i do??

Possibly when you changed to UEFI BIOS the priority settings for your boot device changed? Try using UEFI and looking into the boot priority.
