Solved!

Can't disable legacy boot support in Bios

HP Recommended
HP Z620
Microsoft Windows 10 (64-bit)

Hi,

 

I installed WIndows 10 using UEFI but  couldn't disable Legacy support boot mode in the BIOS.

If I disable Legacy support the PC will beep 6 times and red led flashs on the power button.

 

I don't know if anyone had encountered this problem before or have a solution for it?

 

Help please!

 

Cheers

Just find the answer to my own question.

 

It's the VGA card that's the problem. Its not UEFI ready.

 

After swap with a more recent VGA card I can now disable the Legacy boot support.
