Windows 7: does W7 hate UEFI - cannot install - help please

does W7 hate UEFI - cannot install - help please

Life was so so easy in the days of Bios.

Brand new build trying to install Windows 7 x64 on a new Samsung EVO SSD on a ASRock z97 Extreme 6 board with P2.30 firmware (latest) and 16Gb Ram.

Media

1 x Full Retail W7 x64 DVD
1 x OEM W7 x64 DVD

1 x Full Retail W7 x64 .iso
1 x OEM W7 x64 .iso

I have checked both CoAs with pidgen.exe V1.1.3.590 and they are kosher (OEM & Retail) and not blacklisted by MS.

USB stick bootable using Rufus 2.2 with .iso above installed and modified files in W7 'sources' folder as below.

1. Tried the firmware with CSM switched off and switched on. Makes no difference (I think).
2. Configured install from USB stick to be GPT not MBR.
3. Configured install from USB stick to be USB FAT32
4. Configured install from USB stick to be UEFI NTFS

Everything stops at install routine both DVD and USB stick ' accept Licence Terms and Conditions'. Mouse and Keyboard become unresponsive cannot progress install. Keyboard wired, mouse wireless. Not even 'Alt + a ' works.

I have inserted a PID.txt for with the CoA into the install 'sources' folder to smooth the path. Doesn't seen to work.

I have inserted a ei.cfg file 'reporting' the licence type into the install 'sources' folder to smooth the path. Doesn't seen to work.

I'm missing something here.
( no the answer is not W8 or 8.1)

Am I trying a mixed Bios and UEFI install in a UEFI world ?

Thanks for reading.

Most probably it is not windows 7 itself but the MBR partition table that is used by windows 7 by default. If the discs are formatted as GPT, UEFI is not a problem with windows 7.

You can do two alternative things.

First, boot into the BIOS, set it to Legacy BIOS. Search throughout the BIOS, wherever it is UEFI, set it to Legacy. Then try installing windows 7. It should work.

Second, convert your discs to GPT discs.
You can do in in two ways, destructive and non-destructive.
When the disc is converted to GPT, it is ready for UEFI. Make a UEFI bootable pendrive using Rufus and install windows flawlessly.

Thanks but....

My SSD has never been used or formatted.
I have no Bios its a UEFI.
I cannot convert the new SSD for the OS to GPT unless I run something from a bootable USB drive. But why would I want to do this surely an install process addresses this ?
I tried making a FAT32 partition for a MBR on Partion 1 on the USB drive for a UEFI install. No Go.

I do not have a Legacy Bios option. I have a Compatibility Support Mode but I think that's just for W8.

All of a sudden Ubuntu looks so so attractive.

Well and good. Follow this guide exactly .... Rufus will make a UEFI bootable disc perfectly.

I personally have tried it a few times in essentially identical condition as you are stating, it always worked.

Then once you format the stick using only Option One in tutorial provided in post above, comparing the picture after loading the ISO to make sure settings did not jump around, you must boot the stick as a UEFI device only.

If this fails report back any settings in BIOS setup checking all tabs for UEFI, EFI, CSM, Legacy BIOS, Secure Boot and BIOS Boot priority order.

How depressing. Ubuntu 14.04 ..an OS not renowned for drivers and interoperability. Downloaded, installed & configured in under 15 minutes on the same HW. If it was not for Adobe products I'd be away from Windows forever.

I had no problems installing Win 7 in UEFI on a MBR formatted SSD directly from the CD. You don't absolutely need GPT unless a HDD is larger than 2.2TB. See here.

But you need GPT format to install to UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Forums. See Steps 6-8.

This can normally be reset to the installer's satisfaction by just deleting all partitions to create and format New.

Can we see a screenshot of your Disk Management - Post a Screen Capture Image?
