Dell XPS 12-9Q23 Ultrabook Laptop.
Pre-boot diagnostics passed 100% - No problem entering the BIOS.
I have tried all possible combinations in the BIOS Legacy versus UEFI but am unable to load Windows 7 operating system (I do not have the discs to install Windows 8)
BIOS recognises the external DVD and starts to load windows but stalls on the Windows Logo and the words "Starting Windows"
Any help much appreciated.
