Hi,
There's probably another option behind uefi in the red box
Check in the security section too
Attachment 370359

that setting is enable password for enter bios only

Actualy i cant go back to w7 becuse of my hacked mobo to support sli

Sorry for posting to this old thread(probably should have created new one), but I have exactly the same question: is it possible at all to use windows 7 (x64) in pure UEFI mode? That is not only UEFI/GPT boot, but also all CSM/legacy disabled in BIOS. Has anyone succeeded in doing this? I don't understand official MS position: it seems they say that OS itself should support legacy-free UEFI operation, but some 3rd party drivers(video for instance) require CSM. For me this seems to be not true: with CSM disabled I get stuck even during safe mode(command prompt) boot just after the CLASSPNP.SYS driver is loaded, while with CSM enabled it boots OK. So the problem arises before any graphics/video driver is loaded. Maybe this happens because I have converted my installation from BIOS/MBR, but not initially installed in UEFI/GPT mode? Anyway it's interesting to know if somebody has installed in UEFI mode and has windows 7 bootable with CSM disabled completely.

Without CSM you have no secure boot

I don't use secure boot, just turned it off in BIOS. UEFI install is still useful if I want to dual-boot with other UEFI OS, or just want to have GPT drive bootable. Turning CSM off is useful because it reduces boot time, since no legacy cruft is loaded. You could try to boot into safe mode pressing F8 at the start of loading windows to go into boot menu?
