I am trying to boot Dual boot Kali Linux with indows 10. I already have windows 10 installed and have a bootable USB, but every time I try to boot it gives me the error: "blocked by current security policy". I have already tried to go to the BIOS and then disable secure boot, but when I try to boot again the setting turned to enable automaticly and I get the same error. I have a Lenovo Legion Y520.

Windows 10, Lenove Legion Y520, USB

    It may be possible your company has a group policy that prevents any USB drive form working. They do this sometime to provide increased security. Check with your network admin.

    Is this your personal use/ this system belongs to your company?

    This is important. If this is your office, have you asked your system admin person? Are they know what you are going to do? Have you taken backup of your system, before going to do?

    If it is your personal, reveal that is the OS is licensed/ demo?

    Please provide more details.

    It's not exactly trivial to disable secure boot. Please post the exact steps that you took.

    Probably  system's boot in legacy mode while installing the system can not find a legacy installation. Some change is required in boot/ bios. But be cautious, don't change anything on bios if you are not expert.

    It likely isn't quite "BIOS" but rather UEFI.

    I am having the same problem i have disabled safe boot in BIOS to no avail. Did anyone find a solution? I have been at it about 2 hours now.

    As this is Lenovo, you can try this, first of all completely shut down the system. After few seconds power on again the system. When the first logo screen appears, immediately press F2 (whatever key is assigned) to enter the BIOS. Go to Security & find Secure Boot. Disable Secure Boot, press F10 to save and restart. After that try again.
