I bought new Fujitsu UH572M 13,3" / i5-3317U / 8GB / 500GB + 32GB SSD / HD4000 / Windows 8
I wanted to downgrade from Win8 to Win7.
I cleaned up all partitions on diskpart.
I created Win 7 USB. Get info from this link .
I used this link. On diskpart
6w89n670f
I created GPT for my ssd disk and before I started installation I miss MSR, I choose NEXT and install Win7.
After installation when I reboot Windows it says WARNING Bootable device not found. Continue When I click on Continue I have boot manu: 1. Windows boot manager 2. Drive0 HDD:WDC WD500LPVT-16G33T0 and I can not see my SSD drive.

I've tried everything, have no more ideas :(

Create your USB flash installer using UEFI Bootable USB Flash Drive - Create in Windows
Option One.

Boot the installer as UEFI flash stick, delete all partitions during the install which should be sufficient to allow a Clean Install Windows 7.

If not post back the exact failure point and verbatim error message.

Remember in the BIOS you want Secure Boot disabled (as it must have been to install Linux). Try Legacy BIOS and CSM both Disabled and then Enabled, or with UEFI Boot first.

Sometimes UEFI presents so many problems that users decide it's not worth the paltry benefits so another option which always works is to Bypass UEFI to Install WIn7
 
I have little problem when I try to make USB

. How can I make EFI bootable ISO? My Win7 is just ISO file.

What do you mean by Legacy BIOS? In BIOS I see just "Legacy USB Support (Enabled)

I did everything from a tutorial but I keep get a message "when using uefi target type only efi bootable iso images are supported. Please select an EFI bootable ISO or set the Taregt Type to BIOS", look at a image link View image: 2014 03 17 093030.

Looks like a dodgy ISO. You should be using the official Win7 ISO download.

Where did you get Win7? How is it being activated?
 
OK, I had some verison of WIndows 7 downloded from torrent.

Now I download Windows 7 from a link from tutorial, look at http://postimg.org/image/3u84632uz/ . I startet good in Rufus but after 30 sec. I get this massage error iso image extraction failure look at View image: falure

I took another version (Win7 Pro) and I made USB successfully.

In BIOS Secure Boot is disabled, CSM is Disabled. View image: bios How to find Legacy BIOS to disable?

I tryed first without Disabled Legacy BIOS.

Windows start to go in in setup but screen freeze up on Starting Windows ? :(

What are the settings choices in BIOS for CSM? If there is choice for "enabled" then try that.

Are you getting a UEFI Flash stick choice on the boot menu? What does it say exactly?
 
SOLVED! :D

I changed CSM to Enable and after than Windows was loaded normally.

I had problem before to make USB with Windows 7 Ultimate 64bit, I tried whit 4 different Windows ISO file and I I always got the message "error iso image extraction failure". Than I downloaded Window 7 Home premium and I made USB successfully.

I was on a way to give up, install Win 8 and sell PC.
Thank you very much Gregrocker :)

If you highlight the Secure Boot listing itself it should show you a choice to Disable. Sometimes it's located elsewhere on the page nearby or in the BIOS. There is always a way to disable Secure Boot but it may take some detective work.

Otherwise look at the Manual on the PC's Support Downloads webpage to see if it offers clues.
