Acer Aspire 7750g - can't boot new windows

I want to install new windows on Acer Aspire 7750g, I have windows 7 home premium 64-bit on usb stick, made with Rufus (iso,GPT,FAT32)

Boot menu is enabled and boot priority order is set usb first.

PROBLEM: I can't get Windows boot setup to start. It starts Windows normally (but Windows doesn't work).

I have tried everything I could find on internet but nothing helped.

Can't find "Legacy mode", can't find "Secure boot", supervisor password created, USB port is 2.0, "Advanced" tab not appearing with A+F10

Laptop came with installed Windows 7 home premium, so I tried alt+f10 at start to recover Windows - nothing's happening.

I would be grateful if someone has some advice. (Laptop is from Germany)

Here are some pictures:

Good afternoon Seco !

For this installation, some factors should be seen:

1- ISO must be unique and exclusively mono-version with the standard x64 bits (Utimate, Professional or Home) and with SP1 included
2- The pendrive must be created with Rufus in GPT mode with support for UEFi
3- In bios, the Secureboot must be disabled and the mode set to UEFi
4- The HDD must be converted to GPT
