My friend has an asus eee pc 1018p. It has no cd/dvd drive (neither do he have a usb cd/dvd drive). The OS wasn't working fine, so we decided to restore the system using the provided OS backup from HD. But midway to installation it was interrupted and the computer was restarted (not h/w or s/w issue but we did it). Now we cannot run the backup and we also tried to install windows 7 through USB, but as soon as we start to install the OS, it says that some device driver is missing. It turns out that the OS needs usb device driver to continue. It has USB 3.0 maybe thats why the OS needs the driver. I tried disabling 3.0 and enabling 2.0 but then it does not boot from USB drive for some reason. We are stuck with this. The backup doesn't runs and when booting from USB it says that it needs device driver. Anyone has any idea what we should do?
