I just bought a new Dell Inspiron 7520. It had windows 8 as an OS. I erased windows and installed Ubuntu 12.10 in UEFI boot mode. Now I want to create a Dual boot system with windows 7 because for me windows 8 is one of the worst OS.The procedure that I followed and was unsuccesful was:
-I installed Gparted and created a partion NTFS to install windows
-I changed the bootmode to UEFI with secure mode off
-I created a bootable usb (FAT 32) with windows 7 iso.
But the problem is that when I enter the UEFI boot menu when the PC starts there no option appeared so that i can boot it from the usb.
I also tried to install Windows using a DVD but again the same problem!
Finally I enabled legacy boot option on boot menu and the bootable usb appeared as an option but when I selected it and tried to istall windows at the stage where I had to select the partion that I had created foe windows appeared a message telling me that the partion is of GPT type and windows cannot be installed. Help me plz!
