Can I install win 7 ult x64 to GPT partition drive or should I convert both partition (C,D) to MBR?
How should I set up the BIOS to boot the pendrive?Win7 installer will do that itself. Done it before upgrading win7 to 10 then a fresh win7 install on the same drive afterwards.
I found a program called MSI win 7 smart tool. It adds the driver to the pendrive.Bios to boot from usb

Dvd drive error, youre not booting from dvd so probably win7 is getting confused what usb ports you have. Win7 doesn't have usb3 drivers embedded with the install, it only recognise usb2. It is possible to mount usb3 drivers but that is done yourself. Search Win7 usb3 drivers.
