A required CD/DVD Rom driver is missing


Sep 1, 2017
Hi, I'm trying to re-install Windows 7 (I know it's old) on an Acer Aspire Desktop but the recovery mode is not working. Just fails. Have now tried to a re-install from a DVD Rom with no USB device connected (not even a mouse) and I can't get pass the screen where it prompts for a required missing CD/DVD Rom driver. I have followed all the advice found in previous articles. There is no option in BIOS to switch off USB3 and the BIOS is quite limited. I'm stuck as I can't install Windows from USB or just DVD Rom.
Any thoughts? Thanks
