Laptop came with win8 preinstalled... i want to downgrade to win7 and to dual boot too and to do so i have to convert HD to MBR because from what i understood GPT will not allow dual booting and i've tried to run win7 setup to install into windows 8 partition but it wouldnt let me pick it nor other gpt partitions on hard drives Disk0. i had same issue with my separate win8 setup cd ... it wouldnt let me touch any of gpt patitions they were all greyed out.
i'd prefer not to lose w8 recovery partition if its possible ... what would you suggest
If you have enough hard drive space, you should be able to shrink the Windows 8 "primary" partition by how much space you want for Windows 7. This will be unallocated space afterwards.
You should then be able to select the unallocated space to install Windows 7 on to dual boot with Windows 8.
Since this is an UEFI installation, you will need to create a bootable UEFI 64-bit Windows 7 DVD or USB to use to install with.
UEFI Bootable USB Flash Drive - Create in Windows
created seperate partition and followed your "UEFI Bootable USB Flash Drive - Create in Windows" guide
but wasnt able to test it as i ran into older problem i had when i set up files with copy and paste...
i get error "A required CD/DVD drive device driver is missing" in w7 installation.
to overcome this in past i used "windows 7 usb dvd tool" to create bootable usb which i tried as well this time but neither did it get ride of driver error, but also in bios i couldnt boot with "UEFI USB" option ...
how should i proceed?
Did you also use step 11 in the tutorial since this is for a 64-bit W7?
In addition, make sure that "Secure Boot" has been disabled in your UEFI settings. W7 will not work with it enabled.
step 11 - yes i have copied bootmgfw.efi from current windows 8 folder C:\Windows\Boot\EFI\bootmgfw.efi
yes also disabled secure boot and in asus bios also turned on "launch CSM"
In that case, have your AHCI/SATA drivers (ZIP) version downloaded from your computer or motherboard manufacturer's site to click on "Browse" in the screenshot you posted above, and select the INF file in the ZIP to install them to see if it may work then.
Go ahead and post a screenshot showing the full layout of your Disk Management (diskmgmt.msc) screen to see if it may reveal any issues.
the unknown device is from disabled in cmos touchpad
i have tried using a driver back up tool to back up sata drivers ... then browse for them in installation... did no yeild positive.
i will try right now getting bootmgfw from win7 installation source ...sources\install.wim\1\Windows\Boot\EFI\bootmgfw.efi
if that fail look for SATA drivers online
Progress - I updated the BIOS but what i think did the trick was using windows 7 version of bootmgfw.efi like you stated in your "UEFI Bootable USB Flash Drive - Create in Windows" guide.
Now im stuck at new message while selecting partitions in install
"The partitions on the disk selected for installation are not in the recommended order. Do you want to proceed with installation?"
should i just proceed?
this is my photo

I went ahead and proceeded .. crossing my fingers
