Disabling Secure Boot in a Legacy BIOS (Basic Input/Output System) environment can be a bit different than in a UEFI (Unified Extensible Firmware Interface) setup. Here are some general steps and considerations to keep in mind:

1. Accessing BIOS Settings: To access the BIOS settings, you need to restart your computer and press a specific key during the boot-up process. This key varies depending on the manufacturer but is often one of the following: Del, F2, F10, F12, Esc.

2. Legacy BIOS and Secure Boot: Secure Boot is a feature that is typically found in UEFI environments, not in traditional Legacy BIOS. If your system is using Legacy BIOS, it's unlikely to have a Secure Boot option.

3. UEFI vs. Legacy BIOS: Modern systems use UEFI, which supports features like Secure Boot. Legacy BIOS is the older system and doesn't have these newer features. If you're using an older motherboard with Legacy BIOS, it's possible that Secure Boot isn't available.

4. No Secure Boot Option: If you don't see a Secure Boot option in your BIOS settings, it's likely because your system is using Legacy BIOS and doesn't support Secure Boot. In this case, there's nothing you need to disable.

5. Upgrading to UEFI: If you require Secure Boot, you might need a motherboard that supports UEFI. Many modern motherboards come with UEFI firmware. If you're using an older system, upgrading the hardware might be necessary to get UEFI features like Secure Boot.

6. Checking Documentation: Refer to your motherboard's user manual or the manufacturer's website for specific instructions on BIOS settings. This documentation can provide clarity on whether Secure Boot is supported and how to access BIOS settings.

7. Compatibility with Hackintosh: If you're setting up a Hackintosh, it's important to note that Secure Boot usually needs to be disabled for a successful installation of macOS on non-Apple hardware.

If your goal is to install a Hackintosh and you're using a system with Legacy BIOS, the lack of Secure Boot should not be a hindrance. However, if you're dealing with other security or boot issues, they may stem from different BIOS settings or compatibility factors.
