Thanks, Dave76 for linking me. I installed the BIOS and the secure boot was automatically disabled!

I installed Windows 7 with no problems!

Thanks again theog for this great tutorial. I'm glad I don't have to deal with Windows 8 anymore...

You are welcome, glad to hear you got everything working.

Check to see if Secure Boot is ENABLED in the uEFI/BIOS firmware.
 
I don't know if its a forest for the trees situation (for me or the author) but is this procedure ONLY for branded PCs that came with Windows 8 installed? Or can this process also be used on a home built PC that had Windows 8 installed on it? And if so, does that require a separate purchase of a Windows 7 license?

Welcome to EightForums.

As you have a home built PC, start at Step Six.

Yes, you need a Windows 7 licence.
 
Hi there,

I followed instructions OP wrote but for some reason I am unable to boot to Win 7 installation.

I created UEFI Bootable USB Flash Drive for Win 7, disabled Secure Boot from BIOS and choose to boot from USB but whatever I try to do, Wondows 8 boots and totally ignores my choice. When I make UEFI Bootable USB Flash Drive for Win 8 than I am able to start installation from USB normally. Why is that?

Here is short Youtube video where I show my problem.

I own Asus k55a

Hello Meljunga, and welcome to Eight Forums.

Double check to make sure that the Win 7 USB has been marked as active.

If it has, then please post a screenshot showing the USB in Disk Management (diskmgmt.msc), and a screenshot of the contents of the USB.
 
Welcome to EightForums.

Looking at the vodeo, looks like your USB Pendrive is not bootable.

Is Windows 7 DVD x32 or x64?

Where do you buy your DVD from?
 
Guys, you are really quick in trying to help!

Literally after spending hours and hours trying to figure out new stuff Microsoft introduced in Windows 8 together with new bios I first encountered with, finally I found solution to my problem.

Solution is on this page.

The trick was to copy EFI boot manager firmware file from Win 8 to Win 7 USB installation flowing instructions bellow after I created UEFI Bootable USB Flash Drive :



Now you will need to copy the contents of the windows 7 install dvd to the USB with a regular copy paste from windows explorer.
Once this is done you will need to get a copy of the EFI boot manager firmware file from a computer that has windows 64 bit installed on a UEFI system.
This file is located in C:\Windows\Boot\EFI\bootmgfw.efi
On your USB (Let’s assume it’s drive E:) look in E:\efi\microsoft\boot and copy this boot folder up one level so it sits in E:\efi\boot
Now copy the bootmgfw.efi file from your computer which has windows installed to this new E:\efi\boot folder and rename it to bootx64.efi
Insert the USB in the machine and turn it on and boot into the UEFI/BIOS loader and check for boot options. On the ASUS Zenbook it detected two boot options on the USB drive. One was UEFI and one was regular BIOS. I made the UEFI option the first choice and restarted the machine.
I could now install windows to the formatted existing GPT partitions that were on the machine.

Important!
Besides setting bios to disable "Secure Boot" I had to enable "launch CSM" in order to reach Win 7 installation setup.


Might be useful to update OP for others?

That would be Step Three.

3) Reset BIOS to default, and reboot to BIOS make sure Secure Boot is disabled.
NOTE: Check your manufacturer's uEFI BIOS manual for settings.

I can assure you I didn't miss any step you wrote in tutorial. In my case it was essential to place EFI boot manager firmware file from Win 8 to Win 7 USB installation in order to start clean Win 7 installation from USB.

That part I think would be good to include in very first post, otherwise I not sure what good is it.

I missed that :-)

It is ISO x64 file I downloaded from digital river. I guess it is as Genuine as possible.
 
Hi guys I wonder if you can help me.

I am not a complete novice on the PC but I am checking to make sure I have everything correct before I waste a little more money on a windows product.

Recently in the last few weeks I purchased a brand new laptop from dell. It came with windows 8, The first day of using it was ok a bit slow but i put it down to updates that seemed to be happening in the background. The next few days I started getting niggly annoying little things like smart audio failing, then returning then failing. Followed by catalyst control errors.. Then it started getting annoying where the wireless would continually dissconnect 6 or 7 times a day and would only start working again when i restarted the laptop. Few more days pass and I started getting random errors here there and everywhere from system error to apps freezing even though I wasnt using them.

2 days ago after I log into my user account the desktop appears black and I can see nothing. Task manager would open and everything was running but I could get nothing on the desktop. I tried system refresh and halfway through it crashed saying pc needs to restart. On restart I could get back to my desktop but so many things kept failing I went for a reset of the pc.. after about 3 hours and 70% reset of windows the pc crashes again and says it must restart. When it restarts I was on a loop of "auto diagnosing problem" "cannot help blah blah" for endless hours until one time it booted up to desktop. This time I had no apps, The task bar that pops out with all the options on wouldnt even load. All I had was an empty desktop with windows 8 written in the corner. I managed to get myself into options and one last time tried to restore from recovery and guess what it also crashed halfway through saying the pc encountered a problem and must restart.

Now when I turn on my pc all I get is after about 2 seconds.. "Recovery" a required device cannot be connected.. error code 0xc00000f. It tells me I need a recovery disc which didnt come with the laptop. After about a minute the computer shuts down.

I can get to setup/boot sections if I am fast enough. But I can not access desktop or anything.

My question is if I purchase a Windows 7 new installation disc, Will I be able to run it or will I just get stuck on this "recovery" page. Can it run from setup or boot? Like I said I am not all that advanced with these 2 options. I just dont want to waste another 90 quid on something that wont run once I have it.

While I liked how fast windows 8 got me to desktop, I dont use the apps.. miss the start bar and just am really not comfortable at all with what windows 8 is and the miserable experience I have had with it. So I really would prefer windows 7.

This was my dell order.

Sorry If i have gone on excessively I just wanted to provide all the details.
In simple terms I guess the question is if I buy a windows 7 disc will I be able to run it ok on this system and will it run from setup/boot section since I cant access the desktop.

Kind regards.
 
Hi iloathewindows8

Welcome to EightForums.

1) Return your PC to Dell for replacement or repair.
 
Thanks theog.

Damn so buying a windows 7 install wont solve the problem?
If they repair it I gather they would send it back with windows 8 and I would have to wait a while? Wish I didnt waste 500 to be honest.
