Windows 10: Windows 11 SSD won't boot in either UEFI or CSM

Hi! I installed Windows 11 onto my new NVMe 1TB SSD, and my motherboard won't detect it as a boot option anywhere in the BIOS. It sees it and recognises it, and it will let me set its priority in CSM, but in UEFI mode it posts to BIOS and in CSM mode it tells me to connect a proper boot drive. I've even connected this to another PC, and in he disk utility the partition is labeled as a boot partition. It is partitioned in GPT format and should be perfectly good to go. Any ideas, preferably without formatting or reading the drive? Thanks in advance!

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

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

 

Trouble installing windows 7 on RAID in UEFI

Set up the thumb drive, changed CSM options to UEFI only and booted to windows setup from the thumb drive. Setup didn't see the raid array so I loaded the RAID drivers (I tried the drivers from asus and the ones from intel) and still no luck. Any other suggestions?
