I am having difficulty installing creating a dual boot system. The two OSes are Windows 7 and Ubuntu. The motherboard it's an ASUS P9 X79 Pro that automatically detects if UEFI is available on the DVD or hard drive. I cannot set the system to UEFI.
The hard drives are 120 & 128 GB SSD SATA. On one drive I have Ubuntu installed. I want to install Windows 7 on the other.
Initially when I first installed Windows 7, it created 3 partitions, ESP, MSR, and the OS. However do to some glitches with dual booting, I had to delete both OSes and start again.
When installing Windows 7 now it is no longer creating the 3 partitions, just 2, MSR & OS. I am trying to get it to create the ESP partition. The hard drive is GPT.
