How To Repair Master Boot Record In Windows 7/8/10 – Without CD

My main hard drive died, I disconnected it and connected a different one as the main drive, I did a clean, format, and clean install of windows 7 on my drive. I partitioned it into three partitions since this drive is a terrabyte large. Then I tried to update with windows 10, and it gave me an error saying my windows/system32/ntoskrnl.exe is either missing or corrupt and would not let me exit with the options of f8 or to try again…I know it probably has something to do with the master boot, but it does boot up fine to windows and I checked the bios since I did that first before installing the windows 7 OS, and that looks fine in the bios so it is not that…some suggested it was the keyboard, but I tried that, still wouldn't boot up Windows 10, still gave me the same error. Would doing this in the boot fix that or do I need to do something else to get it to boot up the windows installation disk?

When i type the attrib c ….
It says file not found

PC cannot boot properly. Automatic repair fail loop.

Any work around for windows 8?

Thank you bro.

You fixed my computer from an infinity boot loop thank you I was trying to update my computer and I turn my computer on purpose not thinking about the consequences and ended up with UNDOING CHANGES MADE TO YOUR COMPUTER loop and it didnt do Anything it would turn off and on every 10-20 min repeating it self so I tryed your method and it worked I honestly need to create a backup drive in case it happens again we need more people like you best of luck to your channel!!

what if the error code was 0xc000000f??? what do i do??… or that what if after entering bcdedit /export c:bcdbackup ,,, it says this "the volume for a file has been externally altered so that the opened file is no longer valid"??? wtf do i freakin do??

I did Bootrec /fixboot and it showed me access denied?

When type bootrec /fixmbr
Says
The system cannot find the path specified

Hello! I had to use the bootsect command and all other commands were successful, except: the /rebuildbcd returned "windows installations: 0". i guess my Windows 10 is hosed? any suggestions besides re-installing Windows 10 and wiping everything?

attrib command does not work, I get
path not found – c:boot (Windows 10)?

Thank Your very much
