[dodoiutul2]

So I have an HP Z200 Workstaion for a some time . I want to install win 10 , i check the minimum requirements and it was all good. It had win 7 64bit
The problem is that when i try to boot from usb it still boot from hdd . I change the setting in Bios and nothing. I also change the usb stick , i also try to install win 7 instead . Still nothing
Bios veriosn is Hewlett-Packard .
Its my first time with this kind of Bios and it seems it has few options
I also try to disable secure boot but i can't find it . I read something about Legacy change or something like that , don't know how to do it
When i enter in the Bios and go to system information it said something about Boot Block Date 12/14/09
I don't know what to do pls help
Its my first time posting here so be gentle

You will need to create a bootable USB installer like]http://www.tomsguide.com/faq/id-3694993/create-bootable-usb-installer-windows.html]like so[/url], make sure you're on the latest BIOS update for your motherboard and with the pen drive connected to the rear I/O USB port set the primary boot device to be your USB installer, it should pop up as an option(with your pen drive's name) and have it the highest in the order, then have the HDD as the second boot device.

Disable fast boot, as well as secure boot:
