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 doesnt work. Why is this?

Hi @Saig39 

 

That is because you changed from legacy to secure boot and the disk partition does not recognize the UEFI, then you must reinstall windows, if you want to return to the operating system you must activate the legacy again.

I've returned the BIOS to legacy. After I reinstall windows should I just do the same steps as I mentioned in the original post?

Yes, first switch to Secure boot, and then you must reinstall windows again from an installation USB in UEFI, use Microsoft's media creation tool.
