Microsoft reserves this partition when I choose to use free space to create a partition for Windows installation (it all during the Windows installation process by booting from USB flash drive). If I want to install Windows I can't delete it. May be this is the problem?!

Probably not the problem. I just wouldn't allow Windows to create partitions - just select an existing partition that was setup in macOS, and have Windows only reformat the existing partition.

2012 and older models only support legacy BIOS Mode

Is it true or it's a lie?

Depends on what you mean by support, there's issues like the sound card potentially not starting without a DSDT override but it should at least install in EFI mode.

One thing I just remembered, when you boot the windows install disk there's 2 new icons. I think one is called windows and the other is called EFI. You should select the EFI one if I remember correctly.

Oh, now I know this Windows reserved partition is used for!)) I tried to delete it. Now my computer sees only Windows partition when I turn it on and press the Option key. It can't see even the external USB drives.

Trying to find how to boot even once from Macintosh HD to restore my disk to one OS X partition. I checked via Disk Utility by using Command+R, it's ok, I just can't boot from it. Don't you know how to solve the problem?)

isn't there a startup disk utility on the recovery partition?

I deleted the Windows recovery partition. In Command+R there is only an option to reinstall OS X, but I'm not sure it will help.

Doesn't recovery mode have menus? Install macOS to an external drive, boot from that, and use it to examine your Mac's built-in drive.

Man what a job, for me was so difficult, I did exactly what you did... but I have a problem.

There’s no game activation... any game I want to play crashes at launching. Urgently I need help, I almost not understand anything of computation and programming. I have the same MacBook  as you but i use a Sonnet th3-th2 with a RX480.

i already installed all the drivers and Radeon app, i proved CSGO and GTA San Andreas. Both with errors at launch.

Please someone help me!
