Solved How to install W7 on existing W8.1 machine

[smartem]

HI,

I try to install W7 on my laptop - HP 15g 082no (AMD processor and GPU)- with W8.1 which is

running there.

I want to make a duabl boot, and use both OS.

Read a lot of instruction on this Forum, following manual:

UEFI Bootable USB Flash Drive - Create in Windows

and
http://www.sevenforums.com/tutorial...e-firmware-interface-install-windows-7-a.html

I have to use EFI instalation, because I have a 5 disk totaly, 4 of them used by W8.1, so MBR cannot handle more than 4. And, I dedicated one for W7.

I also Disable Secure Boot in UEFI and ebable Legacy support in BIOS.

First boot device setup in BIOS is USB flash.

When I reset laptop I have this option to boot:

"USB Hard Drive (UEFI) - Netac OnlyDisk"

"OS boot Manager"

"Boot from EFI File"

"USB Hard Drive - Netac OnlyDisk"

"Notebook Hard Drive".

I choose first option - "USB Hard Drive (UEFI) - Netac OnlyDisk" - but when start installation

from prepared EFI bootable USB flash (16 G), I got a message

"missing widows\system32\boot\winload.efi."

Why is reason to installation feild, what is minning of this message?

How many partiotion I need for W7? It will also make new three partition, for boot and repair?
Any help here?
