Home computer system Windows 10 new installation.
Originally a dual system, there is also an Ubuntu.
After Windows 10 is installed, restoring Ubuntu is a problem.
The initial approach is to modify the BCD record with EASYBCD. The operation was successful, but after the system restarts, often the black screen cannot continue.
After trying, the new graphical interface is not displayed properly. Mouse or keyboard If you try to press, you can enter the system. Of course it's not convenient.
This is the initial graphical interface that does not necessarily come out each time.
Now let's start revising.
1 run console in Administrator mode.
2 Back up the BCD record.
Bcdedit/export Save_path
Setting the Startup interface is the command line.
Bcdedit–set {current} Bootmenupolicy legacy
3 Confirm the previous modification.
4 Restart the computer. The familiar interface is back.
EASYBCD supports Windows 10 and Ubuntu 14.04 dual system boot
