The System Won-t Boot. Recover Windows Bootloader with bootrec, fixmbr, fixboot commands - Hetman Software Watch about recovering Windows 10, 8 and 7 bootloader. Very often users face the problem when the operating system will not boot, and in most cases it happens because Windows bootloader is damaged. How To Restore Windows 10, 8, 7 Boot Loader . Contents: ; 1:02 - First way 2:18 - Second way 3:21 - Third way For example, when trying to start the system you have errors such as -BOOTMGR is missing,- -An operating system wasn-t found,- -No bootable device found- and so on. The bootloader can be damaged after installing another operating system on this computer, trying to use the free space in hidden partitions or format them, a failure when installing Windows updates or other system problems, a virus attack etc. Before you start fixing this problem, check the boot sequence in BIOS or UEFI. It could be the root of the problem with booting Windows. So, the first method to fix the botloader will work with all versions of Windows: 10, 8 and 7 (in my case, it is Windows 10). All you need is a recovery disk, or a boot disk /flash drive of the same bitness as your system (in case of Windows 7, only a boot disk /flash drive can be used). If you don-t have any, you can use another computer to create them (you can watch my previous videos to see how to create a boot flash drive or a recovery disk). After that adjust BIOS or UEFI settings to boot from a disk / flash drive and enter Windows Recovery Environment. In the recovery environment, click on Troubleshoot / Startup Repair (in Windows 7, it is also -Startup Repair-). Select Windows 10 as the target system and wait for the process to finish. When it does, the computer will restart into the restored system (don-t forget to change the boot priority to hard disk in BIOS or UEFI). If you saw a message that restore wasn-t successful (it-s often the case), try another method. It is also good for Windows 10, 8 and 7. As well as in the first method, go to the Redovery Environment, click -Troubleshoot- and start Command Prompt. Then enter the command -bootrec /fixmbr- to rewrite Windows MBR in the system partition of your hard disk. When it is over, we can see the message that the operation is completed successfully. Using this command is not always enough (for example, if the bootloader failure was caused by a virus). That is why enter the command -bootrec /fixboot- to write a new Windows master boot record in the system partition. When it is over, close the command prompt and boot from the hard disk. Now you are not supposed to have any bootloader problems. The third method will work with Windows 8 or 10. As I have shown earlier, go to the Command Prompt started in the Recovery Environment. Enter the command -diskpart- and then -list volume- to see the number of the hidden partition. If you have UEFI, this partition will have FAT32 file system and the size of 99-300 Mb, and in case of BIOS, the file system NTFS and the size of 500 Mb or less. In my case, it is -Volume 3- of 99 Mb with FAT32 file system. You should also look at the letter of the drive where Windows is installed (in my case, it is C). After you have seen that, enter the command -Select volume 3- (that is, you select this partition and work with it), -format fs=fat32- (that is, format this partition in teh file system it had before), -assign letter=Y- (assign a letter to the drive; you can choose any letter which is not in use now), finish the work of Diskpart with the command -Exit- and enter the following command: -bcdboot C:\Windows /s Y: /f ALL- (where С is the system drive letter; Y - is the hidden partition letter which you assigned) and wait for the process to finish. After the process is complete, we can see a report saying that boot files have been created successfully. Enter -Diskpart- again, then -select volume 3- (where 3 is the number of the hidden partition for which you have assigned the letter), then -remove letter=Y- (that is, delete the letter of this hidden partition, so that it is not shown in the system) and finish the work of Diskpart again with the command -Exit.- After that, close the command prompt and restart the computer (don-t forget to change the boot sequence in BIOS or UEFI to hard disk). Now Windows bootloader should run properly. Thank you for watching and good luck! If you liked this video, click the Like button below and subscribe to our channel to see more.

I had a working windows8 laptop, and then I tried installing Windows Xp onto a USB drive from the CD
Unfortunately, despite selecting the external drive, it seems to have hosed my installed hard drive's MBR. When I try to boot the laptop normally it says:
-windows could not start because of a computer disk hardware configuration problem could not read from the selected boot disk-
Pulling the drive and examining from another computer, it looks like the Win8 partition and Windows folder is all there.
I've tried the
bootrec /FixMbr
bootrec /FixBoot
bootrec /ScanOs
bootrec /RebuildBcd
as well as EaseUS Partition Master.
yet when I reinserted it back to the laptop I still get the same error. It seems like it's trying to boot as XP yet it's Windows 8. How can I fix this so that it boots to the Win8 partition normally?

I was unable to do the fixboot because of access denied. I was able to do the other recboot options. However the last method (hidden fat32) worked for me after 2 attempts, first attempt went into automatic repair, I don't know what made me try it again but I did it and it worked! So glad I don't have to reinstall windows! Try the last method multiple times, that's my advice.

I was experiencing 'Access is Denied' with bootrec /fixboot, tried everything and finally stumbled across this video. I jumped straight to solution number 3 in the description and followed it word for word (without even watching the video), and it worked! Thank you so much, all other solutions have not worked but this did. You're the best! Good luck everyone else

My bootloader was corrupted after a failed Windows Update. I spent a whole day trying to figure things out since I didn't even know anything about this at all; after hours of failed attempts reading forums and Microsoft's own tech support, I found this video and it saved me from re-installing the whole OS again. This video is super clear and to the point; thank you!

My friend, you have just saved my ass. I was resigned to a reinstall of Windows, except Setup wouldn-t even touch my Windows partition. With your video I was able to restore my Windows installation to full working order without having to reinstall or anything. I-ve liked the video, and will share with everyone I possibly can. THANK YOU MILLIONS!!

Well all i have to say is that you are a lifesaver. I just received my computer back from the service saying that windows cant be repaired and that they would need to perform a format. I believed it could be restored and no format was needed thats why i took it back and you proved me right!! Thanks again and keep sharing the knowledge!! :D
