Windows 10: How to change form legacy to uefi mode

I’m trying to install Linux on virtualbox but it is always aborted that I should enable vt-x. And I tried doing that by accessing the troubleshoot,advanced operations but uefi was not found there and I tried to use the shortcut which is the f1,f2 or f10 key but still remains the same

Legacy to UEFI

I'm debating moving to UEFI form my now legacy BIOS (Award Software Int.) the mother board is a GA-Z68XP-UD3 rev1.0 on the the following link it shows a UEFI BIOS U1J )UEFI BIOS)

https://www.gigabyte.com/Motherboard/GA-Z68XP-UD3-rev-10#support-dl-bios

Currently I'm running the legacy F10 BIOS. Does installing the UEFI BIOS automatically take care of everything to get to the UEFI BIOS? Installing the UEFI BIOS following the instructions using the Q-flash method https://www.gigabyte.com/webpage/20/HowToReflashBIOS.html

What's steps do I take and in what order?

Much appreciated

 

UEFI vs Legacy boot mode

Yep, UEFI mode with Win 10 loading I get the Asus logo.

IIRC there maybe an option within motherboard UEFI to disable the Asus logo but not looked into it. On another forum I have read that what logo you get at Win 10 loading is the easiest way to know what bios mode OS is in.

If system is booting in legacy mode - you get Windows Logo.
If system is booting in UEFI mode - you get OEM logo.

Above also applies to Win 8 but not Win 7.

 

Support Had Me Change From UEFI to Legacy mode in BIOS Re: DISASTER

This was Acronis True Image 2018 support not MS or Lenovo (P51). Those familiar with True Image know that you can create bootable media on a flash drive to run the software. No problem with True Image 2017 but True Image 2018 did not work. Although the flash drive loaded the program the GUI was garbled and I was unable to navigate. Support had me switch from UEFI back to Legacy and that was a bad idea. Sorry for the caps but this was what I wrote back to Acronis support. FYI the rest of the message was not in caps:

SUPPORT: I have discussed this issue with the Experts team and they have suggested testing whether changing from UEFI to Legacy mode in BIOS fixes the issue or not. This step is suggested for testing purpose only.THAT WAS A TERRIBLE SUGGESTION. I WENT INTO THE BIOS AND DID AS YOU INSTRUCTED AND CHANGED FROM UEFI TO LEGACY. I CLICKED EXIT AND SAVE AND WITH THE FLASH DRIVE PLUGGED IN THE 2018 BOOTABLE MEDIA I WENT TO BOOT MENU OPTIONS AND CHOOSE BOOT FROM FLASH DRIVE AND I WAS DROPPED BACK INTO THE BOOT MENU OPTION. SEE ENCLOSED PICTURE. I THEN SELECTED BOOT FROM THE SSD DRIVE AND I WAS AGAIN STUCK IN A LOOP THAT DROPPED ME BACK INTO THE BOOT MENU OPTION. I THEN TRIED BOOTING FROM THE SECOND INTERNAL HDD OPTION AND AGAIN WAS DROPPED BACK INTO THE BOOT MENU. I COULD NOT GET BACK INTO THE BIOS TO CHANGE BACK TO UEFI FROM LEGACY. I HAD TO DO A HARD SHUTDOWN AND POWER BACK ON AND ONLY THEN WAS I ABLE TO GET INTO THE BIOS AND CHANGE BACK FROM LEGACY TO UEFI.

This is a pic of the loop I was caught up in. Why do you all think I was not able to boot either from the flash drive or the SSD or the HDD once I changed from UEFI to Legacy in the BIOS? TIA.
