I bought the HP Slimline 270-p027cb with Windows 10 64 bit installed. I am now trying to load WIndows 7 Pro 64.
I had issues trying to get the install to even load. So I loaded an update forthe bios now I can get to the install screen, where it is asking me to select my languange and hit next to continue the win 7 install.
HOWEVER, My mouse and keyboard are not working, the PC has (2) 2.0 usb ports and I have already tried both.
I have went as far as slipstreaming the usb 3.0 drivers into the win 7 iso image, with no success.
Now I am leaning towards it being a chipset or controller driver problem. I've looked for drivers for the chipset but have not found any compatible with win 7.
Nor have I had any luck with the conroller driver.
