Asus X750J Legacy Boot Support Enable

I’ve seen several people having trouble booting to devices like USB drives or CDs with the new the Unified Extensible Firmware Interface or UEFI UEFI, pronounced unify without the n, was designed for modern operating systems like Windows 8 and replaces the Basic Input/Output System or BIOS

This new interface causes a problem with older or legacy operating systems like Windows 7 or Vista, that were designed to run on computers with a BIOS UEFI is technically different than BIOS, but I will use the terms interchangeable because I am use to saying BIOS, and UEFI is a little difficult to say constantly This video is not on what UEFI is so I will not go into any more detail, but I will include a link in the description for more information This video will show you the basic steps in order to boot to a legacy device, like a USB drive, on a modern UEFI system I will show you the settings using an Asus model X750J

It’s BIOS is a little different than most UEFI I’ve dealt with and a lot of people have issues trying to enable legacy support It is actually quite easy after knowing the proper settings First you need to get to the boot menu On the X750J you do that by turning the laptop on and holding the ESC key Other common keys to access the boot menu or BIOS are DEL, F1, F2, F9, F10 and F12

If you are not sure what your computer uses, try these keys or consult your computers manual After turning and holding down the ESC key, the computer gives me my boot options Depending on your computer, you may go directly to the BIOS Here I can see the hard drive, but not the USB drive I have inserted I want to use my arrow keys to select Enter Setup

You will start setup at the main menu This typically has basic information about the hardware in the computer and the date and time settings You have several other menu options but we are going to focus on the boot menu Arrow over to boot and we can look at the settings Normally you would expect to see all devices listed as boot options, but the UEFI does not allow this

For the Asus, there is a setting called Launch CSM Most people are not use to this acronym so they over look this setting CSM stands for Compatibility Support Module I wish they would type it out instead of abbreviating it That would make it easier for users to find

If you try to enable this setting you will get a warning I tells you that you cannot use this if secure boot is enabled Just click ok and go to the security menu You should see the Secure boot control setting is enabled This setting needs to be disabled in order to boot legacy devices on any UEFI system

Select the setting and disable it After it is disabled, return to the boot menu and make sure CSM is enabled If your system does not have the CSM option, you should be able to select other boot devices now After enabling CSM go to the Save & exit menu Choose save changes and exit

It will confirm you choice Just select yes and the computer will exit and reboot with the new settings Once the computer starts to reboot I hold down my ESC key to access the boot menu You should use your respective key for your model computer You will notice that I now have the option to boot to the USB drive and DVD drive

I am going to select the USB disk The computer should boot the legacy operating system now And you can see the computer is now booting Windows 7 from the USB drive I hope this was informative and helpful to you If you liked the video click the like button, and for more informative videos subscribe to our channel
