Windows 10 Wont Boot, How To Fix Master Boot Record

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.

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! 👍💪

Out of date!
You don't need fixboot, fixmbr or indeed bootrec at all!
It's far easier than you think.
Delete the useless start partition with your favorite Partition tool.

To create with DISKPART at the beginning of the drive:
create part primary size=80 offset=1
Then:
Format quick fs=NTFS label=system
assign (gives a letter)
Then very important:
ACTIVE
list vol (take note of windows and system partition letters, for this example system is G:)
Exit
Then:
Bcdboot F:\windows /S G:
(Sets up all the boot files)
Exit
Reboot

Easy?
I used a Windows ISO 22621.2715

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!)

10:42 how do I boot into recovery mbr?

[Aerceo]

You are a genius! I can not thank you enough for saving my drive. I will definitely make an image of my OS,

Its such a relief to be back in my accounts and I want to send big love from germany.
The 1703 build just magically did it. Insane. <3 All I had to do before was to mark the partition as active via diskpart and it worked afterwards.

PROBLEM SOLVED: For those how need to Dual Boot with Windows 10 Pro and Windows XP in the event that Win 10 is the first one installed and XP is the second one though should be done the other way around: boot firstly in Win 10, install EasyBCD 2.4 and with its help you must insert the Win XP's boot loader in the same one of Win 10s. Hence, afterwards you should be able to have the choosing menu of opting which OS to boot from. Should anyone needs more details on that, revert here and say it!😉😉😉

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.

[vlauv]

I just can't help myself: you're way better than Carey Holzman though he's older than you and it supposed to have much more experience than you! He's just waisting particularly our time by showing stupid tutorials rather by teaching his audience such needed issues! Well done to you once again! I do really appreciate you and all your work here on your channel!😊

Did this successfully and the efi vid. Everything is there as it should be, EFI won't boot. (no file system) (not true). Vid works just fine. There is just one last thing I can't get.

[SametKaratas-dbxu]

I deleted bootmgr and I trying command and it doesn't copied of me. I'm reinstalling Windows

[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.

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' KUDOS to Thank you ~

Or here's another scenario your computer gets hacked the hacker finds your MBR file and deletes it! And if that happens when you log off your computer and when you go to log back in your computer you will either be directed to your bios or your windows advanced settings menu. At that point it's a total shit show from there but it will definitely build up your knowledge and education within computing and IT.

Thank you for saving my life. I do something different way to save my Windows because i have slightly different case.

*1.* I have 1 disk running Windows (labeled NVME1 {C:\}) and then i install another Windows on new disk (labeled NVME2 {F:\}). After that, everytime reboot Windows giving me 2 option boot : NVME1 and NVME2
*2.* I remove all partition on NVME1 and because i want to use it as data disk, but not boot disk.
*3.* After step 2 i got boot error because system can't find booting disk.

*Solution :* i follow some of your instruction
0. Plug my Windows 10 flashdisk (H:\) and boot it, choose repair my windows, choose command prompt
1. Go to boot disk {NVME2}, select vol, set *active* volume using Diskpart
2. Copy all files in directory */boot* in my _flashdisk_ to installation disk {NVME2} using copy command (copy H:\boot\*.* F:\)
now after i have standard BCD file, i execute
3. F:\bootrec /rebuildbcd
4. F:\bootrec /fixmbr
5. F:\bootrec /fixboot
6. restart, and Windows will automate rebuild and check sistem after login

Thanks so much for the video! In my case, I have a dual boot Windows 10/Linux Mint system. While trying to upgrade to Mint v22, GRUB got corrupted. I then removed Mint and GRUB, leaving only Windows 10. But that apparently messed up the MBR. I followed your instructions, but when I reached the bootrec /fixboot command, I got "Element Not Found" error. It turned out that my Windows boot partition wasn't active. So I used your last instruction (diskpart> active) to set it. After that, bootrec /fixboot completed successfully. Following the rest of your instructions, Windows was able to boot!

Hope you see this message sir, I damaged my laptop with a windows 8 iso, so must use a windows 8 iso( same windows 8 iso) or can I use any iso, like windows 10 iso

[vlauv]

Here is the thing: on 16:41 minute it shows that return figure "1", but to me it returned "0", and even so, I continued your indications further more to the end and interestingly enough I still was able to boot again my laptop in Windows 10! Strange or what?! However since I've got Windows 10 on "C" partition and Win XP on other partition - though it should've been on "C" one since the right order of installation should be first Windows XP, necessarily on "C" drive and then any OS(Win 7, Win 10, Win 11 etc) on any other partition - can you please guide me how would I be able to or what and how should I do to see both operating systems and so to be able to choose which one to start with/to booth with?! So far I just can't see that menu to choose from either Win 10 or Win XP and it's booting default in Win 10. Kindly awaiting for your professional reply.

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.

[rhyolitic]

The access denied bit was driving me nuts. Appreciate the ver dependency information. There are tons of write-ups out there indicating that access denied issue is fixable via other commands, but it is not.

[ImvuObsessed]

Hey there. Facing an issue w/ my pc I bought a few months back. Randomly began having a booting issue after not being able to detect my WiFi adapter. I switched over to a WiFi cable hoping it’d fix the problem and in fact made it worse. My pc will no longer boot up. I’m getting error message CRITCAL PROCESSED DIED. I went through a series of YouTube videos and I finally came upon your page. PLEASE help if you can I’m getting gray hairs. 😭
