Fix "Windows failed to start" when Win7 startup occurs. The cause may be a recent change in hardware or software "issue

Yesterday the company finally mercy, unified replacement of Computer configuration, finally to get rid of the "Walking Tractor" era, to catch up with the "era of motor vehicles." But do not want to change the hard disk, because again to install too many things, environment configuration a lot of, so the hard drive does not change, but when I boot up, the tragedy occurred ~ ~, has been prompted "Windows failed to start." This may be due to recent changes to the hardware or software "information, but also constantly restarted. Do I have to re-install the system, all of a sudden go back to liberation? I did it and solved the problem.

　　Workaround One (recommended):

1, directly with the U disk into the PE (I always carry an old peaches PE) system, the general PE system has boot partition repair tool, directly with this tool to repair, restart the computer, directly solve the problem.

　　Workaround Two:

1. Start WinPE with a CD or USB stick and enter the command prompt.
2. Enter "CD \Windows\System32" and press ENTER.
3, enter "Bcdedit", press ENTER, display as follows:

4, the above "Unknow" part is "culprit", the boot partition has been reset, we need to modify the bcdedit.
My Win7 is installed on the C drive, enter the following command, and some may also have a dual system installed, which is determined according to the recent situation:
Bcdedit/set {bootmgr} device Partition=c:
Bcdedit/set {ntldr} device Partition=c:
