Problem Accessing Advanced Settings

[sasuke99]

I tried to change advanced settings with the method described Here

My problem is when I disable legacy support It does not boot from flash drive and I cannot see it in boot options.

I tried the following:

- "BOOTX64.EFI" file from the thread.
- "bootmgfw.efi" and "bootmgr.efi" files from "C:\Windows\Boot\EFI" directory and rename it to BOOTX64.
- Changing usb flash.
- Creating bootable usb drive from command window.
- Creating bootable usb drive using a software.
- Enabling legacy support (I boot from usb but I get a message says "remove disks or other media press any key to restart").
- Change USB 3.0 to between "Auto" and "enabled".
- Make the usb boot option as primary boot device.
