Windows 10: UEFI + Secure Boot not logging into W10 (dual-boot)
UEFI + Secure Boot not logging into W10 (dual-boot)
So I'm the guy who tried to move from Legacy to UEFI some days ago. I managed to move both Ubuntu and W10 to UEFI.
More info on both of the situations here:

It seems that when I enable Secure Boot I keep getting these errors (It works if Secure Boot is not enabled, also Ubuntu boots just fine):
Tried to do a startup repair:
You cannot run the Bootrec commands from the X:\Sources temporary drive. These commands need to be run from the Drive letter the OS is on. Remember, in the RE(Recovery Environment) the OS drive may not be C:
At command prompt (x: sources) type this exactly as written:
bcdedit |find “osdevice” (Must inc ” and the |), the | before Find is the Upper case \ key) press enter. This will tell you what drive letter the OS is on.It may not be on the C: drive.
Now use the returned as the drive letter for OS, for this example, assume C: or whatever drive letter is the os device.
Or, you can type C: and press enter, then type DIR and press enter. If there is a Windows directory under that drive letter, then that is the OS device. Or D: etc Type that drive letter once you know, followed by the Bootrec command.

I'm currently reinstalling entirely windows 10 x64 with uefi , hardware fast boot, and secureboot.
I'm a bit confused because win 10 installer set:
Recovery on partition 1
System on partition 2 (win re)
MSR (not formated) 3
Ok im about to upgrade to win 10 then do a clean install afterwards of win 10, but i wanted to assure i have everything correct before i start. I updated again my profile with Belarc to assure i have a completed list of my software, i notice this...
So, basically if we have a computer that doesn't have a UEFI BIOS with Secure Boot, then we can't upgrade to Windows 10? Am I right or wrong here?
