I currently use a HP ProBook x360 440 G1 from 5 years ago. I've tried to get windows 11 but I need to enable secure boot. But my laptop always shows "Bootloader not found Hard disk - 3F0" error.

 

I enter BIOS -> BIOS SETUP then go to ADVANCED and go to BOOT OPTIONS then turn off LEGACY BOOT while keeping UEFI boot on, after that I go to Secure boot Configuration and turn on "LEGACY BOOT DISABLED AND SECURE BOOT ENABLED" but when I turn on my laptop it doesn't work. I have gotten back to legacy boot and the laptop works fine, but as windows 10 will end in 2025 I want to upgrade to windows 11 but I cant because of secure boot. Why is this?

The problem you are experiencing is that your notebook has Windows installed in Legacy mode and it boots using the MBR partition scheme.

 

When you enabled secure boot, the notebook can only boot up with Windows installed in UEFI mode which uses the GPT partition scheme.

 

Go back and enable Legacy mode and the notebook should boot up again.

 

If you want to enable secure boot, you have two options:

 

1. Reinstall Windows in UEFI mode by booting your Windows installation media from the (U)EFI USB flash drive, not the legacy one.

 

2.  There are some YouTube videos out there that provide the guidance to convert from MBR to GPT without having to reinstall Windows.

 

Back up any files you don't want to lose before attempting the conversion.

After you make the conversion, restart your PC, go into the BIOS, disable legacy mode/enable secure boot.

For option number 1, Can I just reinstall windows using the reinstall option? And then do the same steps again?

For option #1, have secure boot enabled.

 

I would go right to installing W11 by making a bootable USB installation flash drive with the media creation tool from the link below (2nd option).

 

Download Windows 11

 

Boot the USB flash drive from the EFI USB flash drive and W11 should install.

 

Then you can install the drivers and available software from your notebook's support page.
