If you bought a new Asus laptop and want to install windows 7, you’ll find that the installation will hang on starting windows and will not continue. This is because of UEFI ( Unified Extensible Firmware Interface ) which is meant as a replacement for the BIOS. You can read all about it on the Wikipedia page (link)
As it stands, only windows 8 setup can be booted from the DVD drive. If you want to boot a windows 7 DVD , you’ll need to disable UEFI’s secure boot.
On the newer ASUS laptops enter the BIOS. ( press escape continuously during boot until it asks you to go into setup ).
Select Enter Setup:
Go to the SECURITY tab and select Secure Boot Control. Set Secure Boot Control to DISABLED.
Then go to the BOOT tab and select Launch CSM. Set Launch CSM to ENABLED. (This will make booting backwards compatible)
The select Launch PXE OpROM and set it to ENABLED.
Then go to the Save & Setup tab. Select Save Changes and Exit. Choose YES in On the Save & Exit setup.
Your laptop will now restart. And the setup of windows 7 will now continue past the point where it first hung.
