(Proceed at your own Risk) Legacy to UEFI BIOS Change, & Enable TPM & Secure Boot

hi everybody welcome to my channel my name is dennis so i wanted to be able to show people uh i get a lot of questions about converting uh to windows 11 and i ran into some problems with that and the whole reason is because i wasn't in uef5 mode i could not go to secure boot mode uefi went to the bios didn't matter what i did nothing happened but this will help you solve that problem and it's a common error that can happen so if you want to know if you're in legacy mode and how to convert to uefi watch this video it's going to help you but there's a whole lot of other information here as well what to do to get ready for windows 11 and when you're not ready because secure boot won't work what you got to do next here we go okay so we're going to be converting our system from legacy to uefi now i've never done this before i've actually meant to check it out many times when you first put in your nvme drive hard drive whatever it happens to be there's a place to check to make sure you use uf uefi if you happen to make a mistake like i did there's a way to fix it so first you want to make sure you're using windows 10 with version 1703 or higher if you're not sure just push windows r so the windows plus the r key type in winver so w-i-n-v-e-r and press enter the second line you should see the version number so if it's 1703 or higher you're good to go so then you want to check and make sure that you only have three partitions so you can see in here i have system reserve c drive and healthy recovery this is incorrect this is how i already know i'm on legacy but let's double check that so i went in here right clicked okay went on properties this is my drive so go down here click on properties it's going to open up go to volumes and click populate and when you're looking at this if your partition style says master boot record you're in legacy mode right on the other hand if you're in gpt or guide partition table then you're likely in uefi okay so that's the first step so what's the next step now we want to convert it and we want to switch this over and get it to work in uefi we've already gone into the bios that didn't work because it's where it should be so i'm going to show you how to do that now something i want to say first is there shouldn't be any data loss or anything like that in converting from legacy bios to uefi but just in case make sure that you have backed up your system before you convert from legacy to uefi because i'm not going to be responsible if you've got data and you wind up losing it so keep that in mind so the next step is pretty simple i've done a video on it actually how to get quickly to your bios so if you don't understand what i'm doing here look that video up so all i'm going to do is i'm going to restart the system first i'm going to hold down the left shift key click on this so you start button click on your power and go restart hold that button until you see it coming up okay once you get to this part you click on troubleshoot advanced options but where you normally would see uefi this is where things change okay so now we're going to just go command prompt okay system is going to restart okay so mbr 2 g p t space slash validate and hit enter okay so it's telling you attempting to validate disk zero retrieving the layout of the disk validating layout this sector size validation completed successfully okay that's the first step now keep in mind if you see any error messages at this point your disk or your system may not meet the conversion requirements okay so far we're good in this example yours you may not be so just keep that in mind now there's another thing you can try you can type in mbr 2 gpt space backslash validate same as we did before but then add a space backslash allow full a l o w capital f small ul all lower case otherwise okay but we don't need to do that so we're going right on to the next step so we're going to type in mbr 2 gpt space and then the slash again and convert so that's it let's see what happens okay so it says we now attempt to convert the default boot disk if the conversion is successful the disk can only be booted in gbt mode you just the changes can't be undone all right and it is saying fail to update please try to manually disable enable when re before the new system can boot properly you need to switch the firmware to boot to uefi model so this is where we will probably need to go into our bios now and change that so this point we're going to exit out so exit enter and we're going to turn off the pc and we're going to restart and then you're going to have to hit your key to go into your bios so keep that in mind that's what you're going to need to do next restarting in my case it's going to be the delete key okay so right now i'm hitting the delete key that's going to take me into my bios now this is where you want to go in and launch your motherboard firmware settings screen and change it from legacy to uefi in the bios in my bios there's no this is the asus b450f gaming motherboard the original not the two version so you go into your boot menu over here okay so you click that go down where it says secure boot right now it says other os you're going to click on that and go windows uefi mode click on there and now you're going to exit and save so exit save changes and reset and it's telling you what you're doing so click ok ok so i'm back in windows 10 all my icons everything are still there everything's the same but now let's verify if we are actually in uefi mode okay that's what we want to look for so the quick way would be to go in and check the pc health check again and see what that says but let's do it the other way again so okay to verify if we're in uefi mode and if we've converted go back into your disk management click on here computer management so you're going to click on manage go down here and now you can see there's four partitions okay so that tells me right there we're in uefi mode how do i verify that right click on here click on properties click on the hardware tab go to properties go to volume populate it again and now you can see we've switched from partition style guid partition type and now we're in ufi mode so let's verify can we now be ready for windows 11. let's find out okay so we're back into pc health check and we're going to go check now and if everything is right we're going to see it's ready and there you go this pc meets windows 11 requirements okay so you can see all results you can see now we're in pc support support secure boot now and your gpm 2.0 is enabled on this pc and you're meeting all the other system requirements all right everybody so that was the one thing i wanted to make sure to show you i did a video earlier quite a bit ago on how to quickly get into your bios but then people would say well my uefi doesn't show up what else can i do i had other options but with windows 11 it made me realize there was a mistake made so if you've made that same mistake this is how you can fix it convert from legacy to uefi you also have to go into the bios which i've showed everything in the video from start to finish to get you ready for windows 11 and or if you just want it back to uefi mode all right make sure you back everything up first although you should not lose data but don't take that chance that's on you if you do so if you liked the video hit that like if you don't well you know what to do leave me a comment tell me what you thought did you like it did it help you whatever if you have any comments
