Have a HP Envy 17j017cl notebook with win 8 OS. got a virus and decided to recover computer back to factory. Had
an USB flash to restore to original, successfully.
Tried to restore from external backup to put notebook back to latest backup. Accidently used wrong backup, which had windows 7 from another hp notebook. So it loaded the backup, but now the OS is Win 7. Now, none of the "other devices" have any drivers on this machine for windows 7. Tried to repeat the above steps, but no usb controller, network, or ethernet drivers for win 7 on this machine. Cannot boot to usb to restore drive because none of the usb drives work. Tried to copy recover from USB to DVD, but computer would not boot from CD or USB. In the boot manager, it only gives two options, hard drive and efi. ANY HELP would be VERY much appreciated.
