A few weeks ago I showed you how to fix a UEFI boot loader. Today we are going to fix an MBR boot loader. a master boot record partition as it turns out is a lot harder to fix then a GPT partition. But harder doesn't mean its impossible. I'll show you how to do it in this video.

    I love this guy's tutorials man. I haven't used Windows in years as a daily driver and if I get such errors I'll simply revert to a clean snapshot for my VM, but this guy simply has the type of energy for a Youtuber that you want to watch his videos even if you'll never have to resolve such problems. (maybe handy to recommend for a friend though!)
  • Thx for teaching an old dog a new trick. Usually when the /bootfix fails on me, I assume it's because the OS is just beyond repair. Now that I know it's because of 1703, that's a game changer for me! We can collab ANY time you want, brother! 👍💪
  • This was an absolute life saver. I installed a new psu with the wrong cables and something happened to my ssd so that it couldn’t boot anymore. Just went straight to bios. I spent nearly 10 hours troubleshooting and testing components before I found this video. My boot files must have been corrupted somehow and this fixed them. Can’t thank you enough.
  • @SevenFifteenAM
    Thank you so much for this info. Your delivery and content is clean and precise. Explanation of each command cuts down the wall of text I would had to read to truly understand what each command does. I want you to grow as big as other prominent YouTubers because your solutions respect the viewer’s time. Take care.
  • @YorranKlees
    I cannot emphasize how useful this video is. Thank you so much. This particular video will end up in my Watch later playlist, cause I'm gonna use it at some point in the future.
  • @mpdroza
    you are a saver. The way you cover all the 'what if' is very essential. Thank you
  • Great tutorial. There's a bunch of half-ass Windows help channels on Youtube, but this is not one of them.
  • @mrlintonious
    Thanx so much for this. I was stuck with a Boot error after trying a Linux Dual Boot, and then when Deleting the Linux Partition in Windows, as no longer wanting Linux, the PC would not Boot, and gave same error as you had shown. My HDD was MBR, and followed your guide step by step, and now Booting back into Windows. Awesome.
  • @JinnaiT
    I love how calm you are :) what i actually saw on the screen didn't match, it actually said "failure when attempting to copy boot files", but there's nothing that can be done about it.
  • Perfect. Looked around for the reasons why Win 11 was not seeing Secure Boot, and this video nailed it. After removing a 3rd partition, I was able to convert and complete the Win11 install. Thanks!
  • @tharunam
    Using command "dir /a" helped tremendously and I was able to see directories and files that I could NOT before. I agree with someone who said that you are a GREAT teacher. Thanks for all you do for us. With warm regards
  • @TheXBoy5
    I messed up a Linux installation on a drive that I didn't know was MBR. This saved my windows installation, thanks.
  • @EWCRC
    Thank you for the detailed explanation and steps to recover the MBR.
  • @loterius
    Thank you bro. This were incredibly helpful. Avoid me of reinstalling the OS and losing useful software license. Great work. Keep on !
  • @Greebstreebling
    Thanks for posting all this. Even as a technical person, what this tells us is that windows is inordinately complex and for no good reason. My daughter's win 10 disk just gave up and fortunately before it died, I managed to clone it. So to avoid all this horrendous boot nightmare, that's what I recommend - buy another disk of the same size and clone your OS. Microsoft will probably say that's an infringement of the license agreement, but I play fair - the clone goes in my desk drawer until I need it. For those who might complain that this method requires the purchase of another disk, my answer, from my experience of Windows disk failures, is that you're going to need one to replace the failed drive, AND its much harder to reconfigure your new disk when the old one fails. Happy disk drives :) :)
  • @Valery0p5
    Thank you, it was actually MBR2GPT that borked my system, the OEM probably had some funky partitions that the tool couldn't handle. I had to remove those and rebuild the MBR manually like you explained. Let's hope I can upgrade it at some point...
  • @stanknight9159
    Thank you for the detailed but straight-forward video. Before, I just typed things, or recited; Now I know what things do lol. You saved my life! The best get out of trouble video ever.
  • @meysamab7537
    Thank you brother, my system had a problem, with this video of yours, my problem was solved, I am from Iran, thank you for everything
  • @joelbruno7314
    If I had MILLION$ to give you, it would be yours!!!! Holy cats!! I was dead in the water and you resurrected me!! 🙂 I knew what the problem was...just had to figure out a way to resolve it. This video was PHENOMENAL!!! Luckily my Windows installation CD is pre 1703, so I didn't have to fight that issue. I did, however, have to side track a little off your video and find a fix for an "Element Not Found" error when running BOOTREC /FIXBOOT. But once that issue was resolved, everything launched with success exactly as you demonstrated in your video. Just friggin' YUUUUUUUGE KUDOS to you!!!!! Thank you ~
