If we talk about older Windows OS, Windows earlier than Vista requires MBR partition, Windows 7 and Vista only support GPT on 64-bit after you enable a few settings. Most modern systems are made to use the GPT partition, while some still retain support for MBR. The GUID Partition Table is the more advanced and efficient partition standard compared to the old Master Boot Record. Regardless, if you only need to enable secure boot to protect your system, you can skip them.

Also, secure boot works better even in previous Windows versions if you have a GPT partition and a UEFI BIOS mode. However, if you want to enable secure boot for installing Windows 11 or upgrading to this software, you definitely need to execute these steps. You don’t really need these processes if you simply want to enable secure boot. In this section, we have also included how you can convert your partition style to GPT and change BIOS mode to UEFI. You can enable secure boot in a similar manner to disabling it. Press F10 and pick Yes to save the changes and exit the BIOS.Then, select the PK Management option and then Delete Key > OK.Go to Key Management and select Save Secure Boot Keys > OK > OK.Insert a working FAT32 USB flash drive into your PC and get to the Secure Boot configuration.So you need to create its backup first if you use this method. However, this removes the key altogether and prevents you from enabling the feature next time. You can also disable Secure Boot by deleting the platform key. Press F10 and select Yes to save and exit.If the option doesn’t exist, go to Boot > Secure Boot.Select Secure Boot Control and set it to Disabled. You don’t need this step for Legacy mode. On UEFI mode, press F7 to enter Advanced Mode.

You may need to press it multiple times to get the timing right.

During startup, immediately press the F2 or Del key depending on which your BIOS key is to get to BIOS.

So, you may want to disable the Secure Boot feature in such a scenario. Due to this reason, you won’t be able to boot the other OS properly. However, if you are dual booting a non-Microsoft Operating System, such as Linux, it won’t support all Microsoft security keys. Secure boot is a great feature to protect your system from threats.
