Windows 10: Can't install windows 10 with UEFI support

Hi, I created USB installation media and performed a custom install of Windows 10 pro on a brand new NVMe disk and it got formatted as MBR instead of GPT. Windows got installed in legacy mode. I tried following this article: https://answers.microsoft.com/en-us/windows/forum/all/convert-an-existing-windows-10-installation-from/aa8c2de3-460b-4a8c-b30b-641405f800d7 . I can successfully reformat the disk to GPT but can't find the settings from step 4 in my BIOS. I reformated to GPT, reinstalled windows and my disk is still somehow MBR and windows is still legacy. I also don't have "UEFI Fir

Trouble installing windows 7 on RAID in UEFI

As the title says, I'm trying to install Windows on a RAID array in uefi on my Maximus V Formula. When using legacy ROM I can install just fine but I go into CSM and change settings to UEFI only, I can build the array in the UEFI Raid driver (IRST tab in "BIOS") but the array does not show up in the boot menu and when I try to install windows (boot from UEFI DVD drive), The drive does not show up in the Windows install. The next thing I tried was to enable UEFI and legacy oprom in CSM, boot from UEFI DVD drive and install to the RAID array (probably detected by legacy oprom) and it will install. After first reboot, Windows Boot manager will show up as an option in the BIOS boot menu so I set that as first boot device and reboot. I will get to the starting windows screen and then BSOD (too quick to get codes) The last thing I tried was Changing to legacy mode and installing windows to a different drive. once installed, I initialized the Raid array as GPT and rebooted, changed csm back to UEFI only but they RAID array still doesn't show in the boot device list so I repeated the earlier process hoping that It might work because I had initialized as GPT but it still BSODs on starting windows screen. Any help or suggestions would be greatly appreciated

 

Trouble installing windows 7 on RAID in UEFI

I think you were on track with your first try. Windows installer probably needs the RAID driver in order to detect it on install.

 

Installing Windows 7 in UEFI Issues

At the moment my Windows installation isn't in UEFI. I reinstalled in Legacy for the moment to see if I could get help first why my drives weren't being recognized at all other than my ROG RAIDR when installed with UEFI. I'll give that I try tomorrow and post back. I just want to be able to use the internet for the rest of my evening.
