I'm afraid you're finding out what numerous others have who've tried the same kind of thing have found. It's like trying to put a Ford engine in a Chevy. It's not as simple as it might seem. When a computer is built from the ground up with BIOS, motherboard, and devices customized for Windows 8, trying to put Windows 7 on it is much more complicated than it appears, and in too many cases results in the frustration you're seeing. Windows 8 is mostly a Windows 7 base with a totally different user interface. If you want the Windows 7 interface, install the free Classic Start, and you can do everything in desktop mode like you would with Windows 7. Of course MS in its wisdom did remove the old games and XP Mode from Windows 8, but there're pretty straightforward ways of dealing with that too, if need be.
Here's my problem:
I have several Win XP programs that will not run in either Win 7 or 8 - one is a multi-gig of data e-mail app that does not hook into the Registry. On my 7 machine they run perfectly in Virtual Box and VB recoginses any USB device I care to use.
My HP Envy 4-1130us ultrabook came with Win 8 and Virtual Box boggles my mind with its instructions for recognising USB devices & network.
I'd like to roll-back the HP Envy 4-1130us to Win 7. I have the install disc which keeps asking for the installation of a non- specific driver - which I assume is for the Raid configuration of the drives.
I've D/L'ed the Intel Rapid Storage Technology Driver, un-zipped it, saved it to a flash drive, pointed 7 install to it and it basically laughs at me!
Before someone recommends another virtual machine app I've looked at them all and they're a nightmare to set-up even for this fairly sophisticated ole geek.
Can anyone offer any sensible suggestions for 'downgrading' to Win 7
