Troubleshoot Win7 boot up with grub error resolution

Most of the time we may accidentally delete the system files or other misoperation to prevent the system from entering smoothly, resulting in grub. Grub may be unfamiliar to some people because it's not in touch, so when it comes to this, many people may be overwhelmed.

I have encountered a similar situation around me, the students of unknown reasons after the boot can not enter the system, and stay in the Grub page. This may be forced to reboot multiple times to see if you can get in, or simply force the shutdown, for anyone unfamiliar with grub. This is certainly not good, in fact, in the grub under the restart and shutdown can be soft, such as Reboot command is a reboot, halt is the shutdown command. If you don't know how to knock help, and then enter, you'll output a bunch of helpful information.

So how do you get into the system normally? As long as the three-line command is available from grub into the system:

Find--set-root/bootmgr (Enter)

Chainloader/bootmgr (carriage return)

Boot (carriage return)

But this is not fully resolved, if only to here, after each boot will have to knock on the top of the three lines of code, a little trouble.

My solution is to rewrite the MBR to the hard drive boot sector, which is the radical method.

Win7 under EASYBCD boot HDD installation ubuntu mentions a tool easybcd, which is particularly useful in Win7. The task of rewriting the MBR is given to it, as shown in the diagram, and the Write MBR (execute action) is completed.
