"operating system not found" message when trying to install windows 7
a friend of mine has a sony vaio laptop with windows 8 on it,but she wants windows 7(plus there is a problem with the laptop,the internet eplorer doesnt open,the window opens for half a second and then closes,and no internet-related application works).i first used a boot usb,configured the bios so that it boots from external devices first and then used the assist button on the laptop to make it manually boot from an external device.the message"operating system not found " came up.then i extracted the iso to an external hard drive to boot it form there and the same message came up.i even burned the image to a dvd and made it boot from the optical drive,but the same message came up.what can i do?or is there some hardware problem which also explains the internet applications not opening?thnx in advance
