What do I do if Secure Boot is Greyed Out?
1. Disable Fast Boot in BIOS
Fast boot stores some of the boot information in the computer memory, making the boot process faster. While this may be beneficial in most instances, it may interfere with the Secure Boot process and may be why it is greyed out.
Step 1: Restart your computer and start tapping the BIOS key when you see the manufacturer’s logo. The BIOS key is usually one of the function keys, and you may verify with your manufacturer.
Step 2: Navigate to the Advanced tab using the arrow keys.
Step 3: Choose Boot Options and hit the Enter key.
Step 4: Click Fast Boot and choose the Disable option, then hit the Enter key to save your changes.
Step 5: Save the changes and exit your BIOS. Then restart your computer, enter the BIOS again, and see if the Secure Boot option is still greyed out.
2. Set Your Administrator Password in the BIOS
When you set the admin password in BIOS, you ensure only authorized users can change high-level settings, which will fix the greyed-out Secure Boot problem. You may follow the steps below to set the admin password.
Step 1: Restart your computer and start tapping the BIOS key when you see the manufacturer’s logo. The BIOS key is usually one of the function keys, and you may verify with your manufacturer.
