When i try to open the windows 7 install cd/usb it freezes for 1 second on the windows 7 loading icon then gives me a blue screen with the following code: STOP: 0x000000A5. I've read on posts to turn on legacy support which i already did and it did nothing to it, My HP 255 G7 notebook is running Insyde F.39 bios, Does not have any ACPI option nor OS optimizations option.

Hi:
You cannot install or run W7 on a notebook with a Ryzen processor.
That is why you don't see any W7 drivers for your notebook on the support page.
