Windows 10: Unable to enter UEFI mode to change BIOS settings.

Hello,I have recently been trying to restart my computer and boot into UEFI mode so I can access the BIOS settings of my computer, but I am always unable to do so. I am always able to get to the point of restarting and selecting the UEFI mode, but it never actually opens it. It just boots the computer normally to the log on screen.I'm a little lost as I have tried just about any guide I can find and don't have a clue on what is going wrong. I checked and yes there definitely is BIOS on the computer.Any help would be appreciated.Thanks,Sam

Should I change BIOS Mode to UEFI?

You boot into UEFI mode by disabling CSM mode (or possibly called legacy mode) in your UEFI settings. But, until you prepare your hard drive (or SSD) to boot in UEFI, you likely will fail to boot. To convert your HDD or SSD to boot in UEFI mode you could try this:
Convert Windows 10 from Legacy BIOS to UEFI without Data Loss

But, if you succeed in converting the HDD/SSD to GPT, and you can't change you BIOS to boot in UEFI mode, then again you will fail to boot. So, I would suggest that you really know what you are doing before you undertake changing legacy BIOS (CSM mode) booting to UEFI.

I would suggest running Ubuntu in a Virtual Machine rather than dual booting.

 

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.

 

Problem Regarding Bios Change from UEFI to Legacy

I have hp pavilion p045tx with windows 10 pro. I recently install Ubuntu with windows 10 so for that I convert my bios setting from UEFI to Legacy mode for install third party software like wireless Driver and all in Ubuntu.
But after every restart the bios setting change to default and that is to UEFI mode and that will cause an problem of no OS detect. Every time I have to go to bios setting and enable the legacy mode to start my OS. Can anyone suggest me what to do in this
case.
