Windows 10: Add UEFI boot to windows

I installed windows while I was on legacy mode, (I didn't realize that I couldn't turn on bitlocker from legacy mode) I now want to turn on bitlocker, so I went into the UEFI, and tried to turn off legacy mode, it turned off, but when I tried to boot, it failed, I have tried booting into safe mode, also doesn't work, I put it back and it works again, is their any way I can get UEFI to work to boot into windows without reinstalling windows

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.
