Welcome to EightForums.

Take note of Step Three:
1) Downgrade to Windows 7.

2) Using a USB Pendrive on a PC with a uEFI BIOS.
USB Pendrive need to be formated to FAT32 as in

Take note of Step 11 for Windows 7.




I have done everything perfectly, secure boot is OFF and that file is renamed and moved too, still stuck at the loading screen while installing win7. :(

When I load Windows 7 with a Windows 8 install, I have to change the Secure Boot option from Windows UEFI (really Windows 8 UEFI) to Other OS. With the CSM enabled, I can then install Windows 7, but each OEM handles the options differently.

You might check your bios and see what options you have for Secure Boot and CSM, or some option that might look similar, as theog suggests.
