I got a sony vaio e series with windows 8 installed on it. I got it from a friend and was told to re-install windows. It had a bunch of spyware and malware on it. Anyway, when i first tried to boot from my windows dvd i got a message saying "Operating system not found" and when I tried to install windows with a usb, setup ran and i deleted all the partitions and when i tired to install i got this message "setup was unable to create a new system partition or locate an existing system". I looked around and people said to fix this use a windows install disc. So im stuck in a back and forth situation. Also to add, i did change the laptop to legacy boot.
