Hello everyone, I'm new here so I'm not sure if this is the correct place. I went about installing Windows 7, it didn't work so I tried 8/8.1. All the same error:

"Windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Ensure the disk's controller is enabled in the computer's BIOS menu."

I'm running an ASUS Maximus Hero VII, it has the UEFI BIOS and I cannot find any disk's controller or place to change my SATA ports to AHCI. I have double checked and it shows that all SATA connectors should be plugged into the Intel connections, which they are according to the manual. I'm not sure what to do here, or if my error lies elsewhere.

On a side note, for formatting the drive should I just partition the entire drive and format as NTFS? It should be noted that I'm currently using Ubuntu as it's the only OS I've gotten to work so far. So as for drivers/BIOS updates I don't know what to do since this is my first time using Ubuntu.
 
What size is the hard drive? Drives larger than 2TB have issues with installing Windows (Microsoft doesn't like using a hard drive formatted with GPT as a bootable drive - especially in a UEFI install). I have gotten this to work, but I had to use 3rd party tools to make it happen.

Another problem - if there are partitions on the drive of ANY type, Microsoft may not recognize how to remove them. It is better to remove all partitions on the drive, power down, let the BIOS recognize the drive, then boot with Windows.

Lastly, if you have secure boot enabled in the BIOS, this will prevent an operating system from being installed - it must be disabled, the OS installed, then the setting re-enabled.

The drive is a 1TB seagate barracuda. I've erased the drive and it says it's all now unallocated space. As for the BIOS, under the main Boot tab, there are CSM(compatability support module) and Secure Boot at the bottom. CSM contains the enable/disable option. Boot device control to change between UEFI and Legacy OPROM, or both. And where to boot from, i.e. Network, storage or PCI-E.

In Secure Boot, the enable/disable option has been grayed out. I have no idea why. Other options are selecting OS type, Windows UEFI or other. The last option is Platform Key (PK) State.

Unfortunately this video seems to have Secureboot set to disable already. Mine's fixed on enable and grayed. I've looked around and it seems like Secureboot from Asus is manufacture disabled, and that Windows XP and 7 require it to be turned off and Windows 8 requires it on. Only from what I've seen.
 
I disable it on my computers when I install the OS (during the Windows 8/8.1 install, it is automatically turned back on if UEFI is enabled). Windows 10 also turns it back on. It was designed so that viruses/malware would have a more difficult time infecting the root of the drive.

Well I believe that turning it off could possibly help. But I still can't find a way to go about doing it. I did however find the setting to change Sata to ACHI or IDE, but it was already preset to ACHI, which is what I read as the preferred setting. So at this point I'm still lost. I might try to figure out the BIOS flashback or EZ updater that Asus has implemented. Or I may try to write them directly to see their opinion on the matter. Never had this problem before, kind of upsetting it all stemmed from a simple mobo swap. But what can you do.
