Secure boot
Secure boot or Microsoft secure boot is a feature introduced with Windows 8, and included as part of Windows 10. In conjunction with the computer's UEFI (Unified Extensible Firmware Interface) secure boot technology, it helps prevent malware, such as rootkits, from running when a computer boots. Computers with Windows 8 or Windows 10 pre-installed have secure boot enabled by default preventing any changes to the boot settings or firmware unless disabled.
Although secure boot can improve the security of a computer, it also complicates booting from another device for legitimate reasons, such as installing an operating system. If you are having trouble installing or running any software with anything to do with booting, consider disabling secure boot.
How to disable secure boot
Secure Boot can be disabled on a computer by entering the BIOS setup and entering the boot section.
