If you’re having trouble getting your computer to boot from a Legacy device, you may need to fix the Legacy Boot options in your BIOS. The process is different for every BIOS, but you can usually find the Legacy Boot options under the Boot options menu. Once you’ve found the Legacy Boot options, you’ll need to enable them and set the Legacy Boot Device Order.
If you’re having trouble booting from your legacy devices, it could be because the legacy boot option is greyed out in your BIOS. Here’s how to fix that.

What is BIOS?
The Basic Input/Output System (BIOS) is a chip that controls how your computer starts up and interacts with its hardware. The BIOS is pre-programmed with basic startup instructions for your computer. When you turn on your computer, the BIOS is responsible for initializing all of the devices in your computer, such as the CPU, hard drive, and keyboard. The BIOS also provides a set of tools for configuring your computer’s hardware.
If your computer’s BIOS is outdated, it may be causing problems with your computer’s startup or hardware. In some cases, you may be able to fix these problems by updating your BIOS.
Updating your BIOS can be a risky process, so you should only do it if you’re confident that you know what you’re doing. If you’re not sure, it’s best to leave the BIOS update to a professional.
What is Legacy boot?
A legacy boot is a boot process that uses the traditional BIOS system instead of the newer UEFI system. Many newer computers are now using UEFI, which stands for Unified Extensible Firmware Interface. However, some computers may still use the older BIOS system. If you have a computer that uses BIOS, you may find that the legacy boot option is greyed out in the BIOS settings. This can be caused by a number of different things.
One possible reason for the legacy boot option being greyed out is that the BIOS is configured to only boot in UEFI mode. To check if this is the case, you can try booting your computer in UEFI mode. To do this, you will need to change the boot order in your BIOS settings. Make sure that the UEFI boot option is enabled and set as the first boot option. If your computer is able to boot in UEFI mode, then the legacy boot option should be available.
Another possible reason for the legacy boot option being greyed out is that the BIOS is not configured to boot from Legacy devices. To check if this is the case, you can try booting your computer from a Legacy device, such as a USB drive or CD. If your computer is able to boot from the Legacy device, then the legacy boot option should be available.
If the legacy boot option is still greyed out after trying these steps, it is possible that your computer’s BIOS is not compatible with the legacy boot process. In this case, you will need to update your BIOS to the latest version.
Why is Legacy boot being greyed out in BIOS?
There are a few reasons why the legacy boot option might be greyed out in your BIOS. The most common reason is that your BIOS is configured to boot in UEFI mode, and legacy mode is disabled. In some cases, you may need to enable the legacy boot option in your BIOS in order to boot from a USB drive or an optical disc.
Another reason why the legacy boot option might be greyed out is because your motherboard does not support legacy BIOS. In this case, you will need to upgrade your motherboard in order to be able to boot in legacy mode.
Lastly, it is also possible that the legacy boot option is greyed out because your computer’s hard drive is not formatted to support legacy BIOS. In this case, you will need to format your hard drive and install a legacy BIOS in order to be able to boot in legacy mode.
How to fix Legacy boot being greyed out in BIOS?
If your BIOS has a “Legacy Boot” option that is greyed out, it is probably because your system is configured to boot in UEFI mode. To fix this, you will need to change the boot mode to Legacy BIOS.
To do this, go into the BIOS settings and look for the “Boot Mode” or “Boot Priority” option. Change this to “Legacy BIOS” or “Legacy Boot” and save the changes. Your system should now boot in Legacy BIOS mode and the “Legacy Boot” option should no longer be greyed out.
Frequently Asked Questions
What is legacy boot?
When a computer is turned on, the BIOS (Basic Input Output System) is responsible for initializing and testing the computer’s hardware. The BIOS also loads and executes the boot loader, which is responsible for loading the operating system.
In the past, the BIOS would only support a limited number of boot devices, such as the floppy disk drive or hard disk drive. This meant that if you wanted to install a new operating system, you had to first install it on a bootable floppy disk or hard disk.
Today, most BIOSes support what’s known as “legacy boot.” Legacy boot allows the BIOS to boot from a wider variety of devices, including USB drives, CD-ROMs, and network adapters. This makes it much easier to install a new operating system, since you no longer have to first install it on a bootable disk.
However, some BIOSes still don’t support legacy boot. This means that if you want to install a new operating system, you’ll need to first install it on a bootable disk.
If you’re having trouble installing a new operating system because your BIOS doesn’t support legacy boot, there are a few things you can try.
First, you can try updating your BIOS. Many BIOS manufacturers provide updates that add legacy boot support. Check your BIOS manufacturer’s website to see if there are any updates available for your BIOS.
Second, you can try using a boot loader that doesn’t require legacy boot support. Many operating systems, such as Linux, come with their own boot loaders that can be installed on a USB drive or CD-ROM. These boot loaders can be used to boot the operating system without needing legacy boot support in the BIOS.
Finally, you can try using a bootable disk that includes a boot loader that doesn’t require legacy boot support. These disks are typically used to install operating systems on computers that don’t have a BIOS that supports legacy boot.
If you’re still having trouble installing a new operating system, you can contact your computer’s manufacturer for help.
What causes legacy boot to be greyed out in BIOS?
There are a few potential causes for legacy boot to be greyed out in BIOS. One possibility is that the system is not configured to boot in legacy mode. Another possibility is that the system is configured to boot in UEFI mode, which does not support legacy boot. Finally, it is also possible that the system’s BIOS is not configured to support legacy boot.
How do I fix legacy boot being greyed out in BIOS?
If your BIOS has a legacy boot option that is greyed out, it is probably because your computer does not have a legacy boot device connected. To fix this, you will need to connect a legacy boot device to your computer. This could be a floppy disk drive, a CD-ROM drive, or a USB flash drive. Once you have connected a legacy boot device, you should be able to select it in the BIOS and boot from it.
