First of all to ensure that the system itself is not a problem, not at the time of the installation of this situation can be done according to the following methods
First, on another computer, put win8 into the U-disk.
Start with the U disk as the first startup item at startup
Enter the WIN8 installed interface Click on the bottom left corner of the repair
Select troubleshooting, advanced options, auto fix
Enter the command prompt if automatic repair fails
BCDboot x:\windows/s y:
where x is the system disk most of the time it should be C y for the active partition//specific What I'm not quite sure I just wrote a d feel like there's no effect.
Then reboot again with the U disk as the first boot disk at this point, it is now normal to enter the WIN8.
But again, it will go into the Windows failed to start interface, so after entering WIN8 we'll reset the boot with EASYBCD.
Windows failed to start. Fix Win8 boot under interface
