Does Xcode 10.1 update really includes upgrade to Mojave as it says? I don't want upgrade to Mojave.

You're probably actually looking at something depicting multiple updates.

I really need help with my dual boot system, as I can no longer boot into Windows 10. Its boot entry is gone from BIOS, it’s still an option in Clover, but it gives me that blue window telling me that a winload.efi file is missing. I also made a Windows 10 bootable USB drive to repair the Windows installation, but the repair option gave me an error. I tried the bootrec /rebuildbcd command and it gave me an error saying there are multiple indistinguishable devices matching the identification criteria. I’m lost at this point.

UEFI Windows boot files can be rebuilt with BCDBOOT.EXE. You should read related Microsoft documentation.

Thank you, that was very helpful. I followed a guide that uses BCDBOOT and I’ve managed to boot into Windows 10 again.

Hello guys I am struggling to install Mojave with clover on my Y520;
I get the "gioscreenlockstate 3 hs 0 bs 0 now 0 sm 0x0" message before the installator freezes.
I have tried injecting intel and disabling nvidia, in vain.
I have attached my EFI drive contents.
Do you need anything else?
