To start, this is my system.

Lancool mesh 2
MSI MPG Z490 Gaming Edge WIFI
I7 10700 KF
arctic 360 cooler
16g G skill Ripjaws 3200 ram
2X ADATA XPG SX8200 Pro 1TB M.2's
INTEL SSD
Samsung SSD 860 PRO
EVGA G3 750W supernova
EVGA XC3 3070 ultra

Windows is installed on one of the ADATA M.2 drives, closest to the processor.

Everything went smooth with this build, and I was finally able to get a 3070. I want to enable to resizable bar in bios, but I'm running into issues.
Updating bios to v .16 went fine, but after the boot, bios wont find my M.2 drives to boot anymore. I had to switch to CSM mode to find them and boot into windows, UEFI wont show them as an option. My windows drive is set as a MBR, the data M.s is set as a GPT, but neither of them show up as a boot option. In windows, bios mode is set to legacy. Bios version American Megatrends Inc. 1.60, 2/1/2021. I see the option to enable to resize bar, and can select it, but it shows up as off in Nvidia control panel.

My research has led me to believe it can only run in UEFI, which I cant boot from, because it cant detect the NVME drives, and just reboots to bios. I read my boot drive needs to be a GPT drive to be detected, in which case, why doesn't it detect the other drive? So is the fix here to change the MBR to to GPT, (convert, or reinstall windows) and set bios to UEFI off the bat? or am I thinking about this too much and missing an easier fix?

I'm sure I am missing a bunch of useful information here, im only moderately experienced with messing with bios, and drives. I don't want to do any damage or lose data. Thanks for any help, and ill send more info if needed.
 
to convert windows 10 from legacy bios to uefi, u can open cmd with admin rights
then run those 2 commands:
mbr2gpt /validate /allowFullOS
mbr2gpt /convert /allowFullOS
if it says all done, then reboot to bios and switch to uefi

Thanks, I got that done, and set to uefi. Still won't work, evga precision update for the vbios won't work, and gives me an error to contact my motherboard vendor. Which I did, but they just told me it should work. Not sure what I'm missing, but oh well. I'll try again down the road maybe. Little performance bump isn't worth the hassle.
