how can i down grade the notebook HP 15-f009wm from w8 to w7.

when im trying to do this send a windows that ask for cdrom / dd rom driber missing. insert the location of the driver and next to continue, cancell or abort.

I can not go more of this step on the begining.

they told me that they does not bring support to oldest OS like W7. But I can install manually each driver.

just that I cannot install W7.

I heard some people have installed W7 on this machine

thank you for the info

I found where my proble was.

the real problem is that the commputer has 2 usb port 3.0 and 1 USB port 2.0 by hardware.

The bios does not have the option of change usb 3.0 to auto or 2.0 then by default always are fix.

Then i was placing the booteable USB in the USB 3.0 ports and the windows installation start and boot normally but send  the error of missing CD/DVD and the driver and the HDD can not be viewed.

the Solution was place the USB in the only one USB 2.0 vailable in the computer and the W7 installation was suscessful

that is the problem the USB needs to be in the USB 2.0 port to get see the HDD and downgrade the W8 to W7 in this particular model.

I will instaledl those  drivers, the only one that is not working is the LAN all of other are working

thank you
