My website: http://www.musicarta.co.uk YouTube channel: http://www.youtube.com/musicarta Facebook: http://www.facebook.com/pages/Musicarta-Computer-Tutorials/139191476140274?cr... Twitter: http://www.twitter.com/Musicarta Google Buzz: http://www.google.com/profiles/musicarta Digg: http://digg.com/Musicarta This video will show you how to repair or fix the MBR. The 'MBR' stands for the 'Master Boot Record' and it's the information in the first sector of any hard disk. It identifies how and where an operating system is located so that it can boot into the computer's main storage or random access memory. So essentially, if the MBR gets damaged or broken, you may not be able to load any operating systems.

My problem is a Dell laptop with a soldered SSD and RAM, I cannot change the SSD. The computer's bios doesnt detect the integrated SSD anymore, but booting into Ubuntu lets me see the SSD. So its a corrupt MBR. Can this be repaired?.

Very appropriate and well done video. However I had a problem with the second command (bootrec /fixboot) it showed me the following error; "Element not found" so my problem still persist. Do you have any idea what it could means and how it can be fixed? Thank you for you reply.

I've tried many fixes, including this one, to re-install Windows after apparently deleting my MBR. Windows would not install. I finally installed Debian successfully thinking that I could then re-partition my drive and install Windows 7. Windows 7 installation will not work, since it's an upgrade. Apparently it's still looking for the MBR - which was deleted even before the drive was formatted during the Debian install. So, the bottom line seems to be that Windows Update will not install without an MBR and this fix apparently must see the MBR or sector (?) before proceeding. I'd be pleased to have your comments.

Installed a brand new dell hard drive into my desktop and apparently had a whole mess of shit installed on it already. Even with no hdd connected to the machine I still get that no grldr message. Followed this video but my os (win7) isnt listed in the recovery menu. Therefore /fixboot didnt work for me. Anyone can help?

I dont even have the option to select windows7 from that list. cmd just says x:sources instead of x:windows\system32
bladadidoblah (1 year ago)
i had the same experience right now on win7. had tried startup repair and also bootrec but i only see x:sources it can't even detect drive c: where i think my mbr is. i have 600gb with 3 partitions, 1 part is system reserved. how someone can help share their positive experience. email me @ [email protected] coz im not sure if i could still read your response. TIA!!
Mad doX (3 years ago)
+Suraum Chetty for me .cmd just said x:sources aswell, but i got it fixed on my second attempt though. i first did exactly the same as showed in the video. then my second attempt after typing in the two bootrec lines, i closed the .cmd and then instead of clicking on restart on the bottum right i clicked on startup repair.. which fixed it i guess. maybe this helps

How do you fix the mbr on an external drive?
Joseph Sack (1 year ago)
1. Open Command Prompt and type: chkdsk /f c: (replace c with a drive letter of your external hard drive); 2. Hit Enter to let the checking process to run; 3. When it’s finished, type: exit and hit Enter to finish the process. After this, your not responding external hard drive shall show up now.

The PC I want to fix has Windows 7 64-bit while the other 2 PCs I have access to have Windows 7 32-bit and Windows 8 64-bit. What should I do?
Grinsekotze (4 years ago)
The problem might also have been that the computer I wanted to make a repairdisc with has Win7 Ultimate while the one I wanted to fix has Home Premium. Whatever, I asked a fried with the same version of Windows to make a repairdisc and it worked perfectly. (I'm actually writing this on the fixed PC :D) Thanks guys!

Are these two commands ("bootrec /fixmbr" and "bootrec /fixboot") also the same commands used for Windows XP repair?  I had read elsewhere to just use "fixmbr" command from command prompt window, for Windows XP.

or when you setup a RAID array and you leave any Initialization on, thus deleting MBR.
Irakli Isakadze (4 years ago)
Thanks a lot for this quick and simple tip. This saved my ass.. I ghosted system drive thinking that it will be simple enough and after trying to boot it up i got an error message, some sort of signature problem which was related to MBR, i spent hours trying to find the way to fix this without reinstalling the entire system and here we are, this was the BEST way of fixing this and also reminded me that it's always a good idea to make/keep a repair CD for your system. Thanks again.

+licarire Whoa whoa whoa, are you fuckin kidding me tuff guy? I know this is an old comment & I'm certainly 'Joe Nobody, I gotta say I sure hope my response still somehow reaches you. And B4 I go off on my own tirade of how incredibly shitty a thing for a stranger to do to another person completely UNPROVOKED, & how hypocritical your intensely aggressive & just plain nasty reply is, I want to at least make sure this wasn't a classic "I was having a REALLY bad day & I lost my shit that day, sorry" type post most people are guilty of at least ONCE in their life. So mate, which is it, chalk it up to a bad day, or are you a total thunder-prick like this to everyone? 👎👍 😤

You are an EdOT. Everybody knows how to backup and reinstall an OS. The question were: how to repair the OS without loosing the data or backing it up. Next time keep your mouth shut and answer only strict to the subject.

I really need some help!!! When I get to the system recovery option, I don't have an operating system to pick from, what the hell do I do!?
ImEsmeralda (5 years ago)
I got an Operating System Not found error when turning on computer. I made recovery disc from another computer also using window 7 like the one im getting error on.All of the steps worked up until i got to System recovery options. There is no Operating system to select. Any suggestions on how to get it to show up on that screen?
James C (5 years ago)
Good tutorial. I went through all of the options you described after getting the BOOTMGR cannot be found message. I created the Windows 7 system repair disc (DVD), then got to the point where I received the following message: error 0x4001100200001012. I tried to boot up again from the repair disc, and after loading Windows files, a black screen with the cursor shows up and nothing else happens. When I remove the hard drive and put it into a reader, I can see the files. Suggestions??
