Can't get to UEFI boot only on Legacy Support

[Edrian456]

My laptop can't boot in UEFI mode only on Legacy Support, if i change it anyway to UEFI the laptop will show the "Boot Device Not Found" if i started the laptop. Guys can you help me how to change the boot from Legacy Support (BIOS) to UEFI ?. I dont know whether the Windows installation is in uefi mode or bios mode because i send my laptop to repair shop before this. I got so many virus that eventually prevent my laptop from running  on my laptop before & the technician says that i should format my laptop & do clean windows installations so i accept it. After that, everything is fine except the boot mode issue. I want it back to UEFI rather than BIOS because my laptop a bit slow than usual. I heard that if you OS is windows 10, you can change it easily for like 3 second in the MBR2GPT?.. or is there other save method ?

Hi! @Edrian456, Welcome to HP forums.

I understand you have issues changing from legacy to UEFI on your PC.

Don't worry I'd like to help you out.

Did you make any software or hardware changes on your PC?

Excellent description and a great diagnosis done. It is greatly appreciated.

Try few steps recommended below.

If it a new PC it will be configured with UEFI by default, you don't have to change any settings.

Unified Extensible Firmware Interface (UEFI) is firmware code from a chip on your motherboard that provides extra functionality, beyond the Basic Input/Output System (BIOS). UEFI is a way to do things with your computer before an operating system is loaded. To name a few features, UEFI can provide extra graphic menus and system information on a computer, and basic diagnostics on both a computer and a tablet. How does it do this? UEFI works with the BIOS to initialize the computer or tablet's hardware before handing hardware control over to the operating system. UEFI can also load and display software programs from storage devices to provide even more functionality, such as more detailed system information and extended hardware diagnostics.

Refer this article to know more information about UEFI and the Startup Menu.

If it a new PC it will be configured with UEFI by default, you don't have to change any settings.

To check if your PC is running with UEFI or legacy try the steps recommended below.

Open Run, type MSInfo32 and hit Enter to open System Information.

If your PC uses BIOS, it will display Legacy. If it is using UEFI, it will display UEFI! If your PC supports UEFI, then if you go through your BIOS settings, you will see the Secure Boot option.

Or you can try the steps below.

To determine whether your PC is using BIOS or EFI/UEFI please follow the steps below:
Start your PC.
Go to Start > Computer.
Navigate to C:\Windows\Panther
In the folder named Panther you will see a text file titled setupact.log. The file will automatically open in Notepad.
Once you have opened setupact.log, click Ctrl+F to bring up the Find box and search for an entry named Detected Boot Environment.
Once you find Detected Boot Environment, you will notice the words BIOS or UEFI mentioned as follows:

Callback_BootEnvironmentDetect: Detected boot environment: BIOS

OR

Callback_BootEnvironmentDetect: Detected boot environment: UEFI

Hope this answers your query! 
Have a great day ahead! 🙂

@Edrian456, 

I am responding on behalf of @A4Apollo as he is out for the day. It is great to have you back and your patience is greatly appreciated.

I checked the specifications of your computer and see that your computer doesn't support RAID.

Hope that answers your question

Good day! Take care 🙂

Cheers!
