You may change the default bootloader using the BCDEdit command.

Run CMD as Administrator and enter the following commands:

• View the current default operating system entry:

    bcdedit /enum {bootmgr}
  

• List all existing entries; note the identifier for the entry that you want to be the default:

    bcdedit /enum
  

• To set a new default (where <id> is the identifier for the new entry):

    bcdedit /default <id>
