Windows 7: Installing Windows 7 on a Windows 8 pre-installed laptop

Installing Windows 7 on a Windows 8 pre-installed laptop

I've tried several options, but none works. My laptop is: Acer Aspire E1-571 and it has EFI ( and legacy bios). I already disabled the Secure boot and followed the tutorial how to make a UEFI bootable windows 7 installation usb.

The problem is:

If I boot with the UEFI windows 7 USB in Uefi mode, it will not recognize the usb, the only bootable option will be: Windows Boot manager.

If I boot with a regular windows 7 USB in BIOS Legacy mode it will, upon getting to the screen where you select the drive you want to install it on, say it is incompatible with GPT partitioned drives. I have been googling all day long and this is driving me crazy!

The reason i want a dual boot is because i want to be sure the drivers are fully compatible (yes i did research), so if anyone could help me out, thanks a lot!

1) Downgrade to Windows 7.
Downgrade Windows 8 to Windows 7
Warning you must have the UEFI/BIOS firmware setting in Step Three set.


2) If Using a USB Pen drive on a PC with a UEFI BIOS.
USB Pen drive need to be formatted to FAT32 as in
UEFI Bootable USB Flash Drive - Create in Windows
Take note of Step 11 for Windows 7.
Also you will need to use a USB 2.0 port, as there are no USB 3.0 drivers in Windows 7.

Yes, i've read that. But the UEFI boot manager will only display windows boot manager, while i followed the instructions on the tutorial, like 5, 6 times over and over! It does not recognize the usb in UEFI mode, only in legacy but then I can't install on the Gpt disk!

Yes i saw, but it's just not in my BIOS? I mean like, i only got the tabs:

Information - No things i can change here, just info
Main - System time, Network boot [ disabled], F12 Boot menu [ Enabled], Wake on LAN [ disabled], SATA mode [ AHCI] (Can only choose between AHCI and IDE!)
Security - Supervisor Pass etc..., and the option to select an UEFI file as trusted for executing (any helpful??)
Boot - Boot Mode [ UEFI] / (other option is Legacy BIOS), Secure boot [ disabled] (weird thing is: Information shows: Select boot type to Dual type, Legacy type or UEFI type.) But there is no Dual type!
Exit - save changes, discard etc...

This why you can not install Windows 7 x64 in UEFI mode, as the the option is missing.

Damn, all I wanted it safety. If windows 7 will not run good that i could return to windows 8, are there windows 8 iso's online which i can use with only a product key?

And should i choose to use legacy, how can i clear EVERYTHING (should i clear all partitions? Got like 5, recovery and other things)
