    Intel Desktop Board DZ77SL-50K does not recognize any bootable media in UEFI mode

      Hello everyone


      I am trying to install 64-bit Windows 7 on a PC with DZ77SL-50K and a 3TB Seagate internal HDD. The problem installing the OS is that after enabling UEFI mode, which is said to be necessary in other forums, the motherboard no longer recognizes the Windows 7 installation DVD although the DVD drive shows up in the boot menu and I selected the DVD drive to boot from.


      Previous to this incident, I installed 64 bit Windows on the same 3TB HDD with the UEFI mode disabled. Then after the first reboot, it would no longer boot.


      Please anyone advise me what could be done to get the motherboard to recognize the Win 7 installation DVD in UEFI mode.
