Step 8... You might receive a "Windows can't be installed on drive 0" warning, but as long as you can click on the Next button, you're fine.

I am getting the error and unable to click the NEXT button.

If I partition my 120gb ssd and create 1 20gb partition for installing windows on it. Will setup still create the ESP/EFI partition needed for my machine (not talking about the MSR partition)?

Hello Pete, :)

Sorry, but no. To have all the UEFI partitions created, you'll need to clean install Windows on an unallocated disk instead.

My head is spinning. To be clear there can exist the following partitions. Not sure if WinRE will be created on a UEFI system for whatever reason.

WIN RE
EFI/ESP
MSR
System/OS
Factory Recovery

AFAIK. WinRe, MSR are not needed. Recovery is not needed for my system as well.

How to avoid the WinRE and MSR?

Hi,
Why would a recovery partition be created that would only be created coming out of the box from said seller = asus/ dell/......

If you use UEFI it will create a small, 128MB IIRC, partition at the root of the drive as this is needed for UEFI to work, Think of it as a type of MBR

If windows is installed onto a clean disk it will add the System Reserved partition, Size will depend on OS installed but Windows 7 defaults to 100MB

If you pre allocate your preferred partition scheme then Windows will install it's system files onto the partition you select for the Windows install as it always did. The potential issue here is that boot errors may bork the whole Install whereas the separate System Reserved partition is more robust and less likely to effect the actual windows install - this is of course your choice to make

The other partitions you mention are I think all either OEM recovery partitions or different naming conventions for parts of these and are imaged onto the disk by manufacturers, as stated above, I've seen up to four partitions involved in OEM recovery options on a single drive

Does one need to wipe the entire drive clean before installing with gpt/uefi?
Or can you clean the disk and partition it. If you wanted to clean install windows7 on a smaller partition?

If you wish to install windows into an existing partition them this will be no problem, The parts of the system that are normally installed to their own small partitions, (hidden), will be placed at the root of the specified installation partition. Of course this is not as efficient or secure against possible future issues but it will work just fine - Just be aware that an issue with any of the parts of the system are capable of taking out the whole system, which is less likely with the preferred layout

So I deleted all the partitions, converted to GPT, booted the Windows installer via the UEFI selection and proceeded with installation. I verified it was installed via UEFI by checking I had the System, MSR, and Windows Partitions. I also checked some log that indicated that the detected boot environment was EFI.

Everything is running fine but I plan on dual booting to OSX later and discovered I need to have CSM disabled. I contacted EVGA and asked them for a UEFI compatible BIOS and they gladly obliged. I went into my bios and turned CSM off. The computer will POST and starts loading Windows. The animated logo will show and just prior to showing the desktop, it reboots.

The bios gives the following message: "The current BIOS setting do not fully support the Windows UEFI mode. The CSM (Compatibility Support Module) settings have been changed for better compatibility. For further adjustments, press <F1> to enter BIOS Setup. If No adjustment are needed, press <F2> to confirm the current settings and enter OS directly."

I thought oh Great, now I have to reinstall. So before I wiped the drive again, I unplugged my SSD and storage drive to try installation to the 180GB drive I intend to use for OSX later. I again turned CSM off and tried booting to the UEFI Windows DVD. It does the same thing, just prior to showing the installer, it reboots. I'm not sure what is wrong. Do I have a Bios setting wrong? I updated all the drivers directly from the manufacturer for Intel and Nvidia. I'm pretty sure Secure Boot is turned off, I have "Other OS" selected. It still says Secure boot is enabled but not Loaded but I guess that's normal for Asus Bios's? I also turned off Fast Boot because I thought it doesn't work with Windows 7, not sure.

My hardware:
Asus Gryphon Z97 running latest BIOS
Intel 4690K Slightly OC'd
EVGA Geforce 660 FTW ACX w/ UEFI Bios
LG BluRay Drive
Samsung Evo 850 SSD 250GB
HGST 7K1000 Travelstar 1TB
Hitachi 180GB
I experienced the exact same issue as you. I have Z97-A/USB3.1 board. Got the same message. Did you ever solve the problem? The only way I was able to install and run Windows 7 Home Premium was with CSM enabled. Windows 7 still installed as UEFI and boots with the UEFI into Windows 7 but I was hoping to disable CSM which I can't do.
