We need you to fill out your specs so we can help you c:
You can look up the model of your computer and search up what button makes it go into the BIOS when it boots up if you are not feeling like posting your specs.
Sorry to be so long in answering, My laptop specs:-
Fujitsu SiemensEsprimo model V5535
Windows8
Bios Phoenix V1.03 11/30/07
1.60GB Harddrive
1790mb memory
Have now entered the Bios, selected start from CD, but it still loads windows8 not install windows7....:devil:
In addition to the other steps I gave you earlier, on a Win8 PC you'll also need to disable Secure Boot in BIOS setup to install Win7: Downgrade Windows 8 to Windows 7
If you're not willing to mess with UEFI BIOS yet then you can more easily install Win7 normally to an MBR disk using Bypass UEFI to Install WIn7
