If you run multiple OSes to separate work, play and music, then renaming your OS options will help a ton more than “Windows 10 partition 1” , “Windows 10 partition 2” and “Windows 10 partition 3”.
To change the default OS to boot
- Open msconfig
- Select Boot tab
- Pick the OS in the list, and “Set as Default”
To change the names of the options:
- Run “cmd” or command prompt with Administrative privileges.
- Run “bcdedit”
- You will see a list of particles and each with the “Windows Boot Loader” heading.
- Find the identifier of the OS you want to edit. i.e. “{current}” or “{b56096d4-9ad0-11e8-9158-daa89f8dd4f4}”
- Run bcdedit /set {current} description “A-NAME-I-LIKE”
