How to fix the boot boot problem in Win10 dual system

After the release of Win10 preview, many users have chosen to upgrade, but some users are not worried about the new system incompatibility, but they are not upgraded immediately. Ideas, so many of them choose to install dual systems. Although the dual system seems to solve this problem perfectly, the trouble does not end there.

New problems come one after another. Booting is a Metro boot menu. No matter which system you choose to boot, you must restart it. It is very painful. It is automatically repaired by ntbootautofix, but it has no effect. After finally groping for a while, I found a way to solve it. The following are the specific steps:

1. Download NTBOOTautofix v2.5.7

2. Double-click to open---Select 2 [Advanced]---Select 4 [View/Manage BCD Boot Configuration ] you will see the following

A selection reselection ---- 0 M

choice --- Back reselection after B

---- select after M

restart, you will find that you are familiar with the boot screen and back again. Note: Because it is a method of personal exploration, it is impossible to confirm the consequences of such a modification, so users who want to solve the problem by this method need to be carefully considered to avoid other consequences.
