Windows 10: How do I get my screen to show the UEFI BIOS?

I think this happened when I made the switch from windows 10 to windows 11, basically, switching to windows 11 put me on CSM support instead of UEFI and whenever I change from CSM to UEFI, I boot the BIOS and my screen is just black with no signal, I can boot the CSM BIOS but not the UEFI BIOS. I have already taken the cmos battery out of my motherboard lots of times and the same issue keeps on happening. The reason i want to access UEFI bios as well, is because there are many other important settings I need turned on in there such as secure boot and TPM 2.0. Please help I have no idea what'

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

Thank you for posting in the Microsoft community.

When a MBR hard disk is converted to GPT, if you can't get into the system, it's usually due to incorrect BIOS settings or no UEFI boot. Here are the steps to solve this problem:

1. Enter PE system: Use a USB flash drive to boot and enter the PE system (pre-installation environment) to make sure the data is normal.
   
2. Check the BIOS settings:
   
   • Make sure UEFI boot is set in BIOS.
     
   • If the BIOS is set to UEFI boot, but the partition is still MBR partition, you need to modify the BIOS settings to match the hard disk partition mode and boot mode.
     
3. Use a PE tool that supports UEFI: Make sure the PE tool you use supports UEFI repair boot.
   
4. Create an EFI system partition:
   
   • In PE system, open "Disk Management", find the SSD (usually labeled as "Disk 1"), right-click and select "Compress Volume" to compress about 500MB of space.
     
   • Open a command prompt, type `diskpart` and enter.
     
   • Use the `select disk` command to select the SSD.
     
   • Use the `create partition efi` command to create the EFI system partition.
     
   • Format the EFI partition using the `format fs=fat quick` command.
     
   • Use the `assign` command to assign a drive letter to the EFI partition.
     
5. Bootstrap Repair:
   
   • In a command prompt window, type `bcdboot x:\windows /s y: /f uefi`, where `x` is the drive letter where the system is located in the SSD and `y` is the drive letter of the EFI partition.
     

Hope the above information can help you
