Chapter 23: Exploring the Windows Boot Environment
This means you could enable PAE for the operating system identified by this boot
loader identifier:
Windows Boot Loader
-------------------
identifier {0c728e1b-d009-11da-b18b-9dc1d02cdda0}
using the following command:
bcdedit /set {0c728e1b-d009-11da-b18b-9dc1d02cdda0} pae forceenable
Changing the Operating System Display Order
You can change the display order of boot managers associated with a particular Win-
dows Vista or later operating system using the
/Displayorder parameter. Follow the
parameter with the operating system identifiers in the desired display order.
This means you could change the display order of the operating systems identified in
these BCD entries:
Windows Boot Loader
-------------------
identifier {0c728e1b-d009-11da-b18b-9dc1d02cdda0}
Windows Boot Loader
-------------------
identifier {263bf496-4ab4-11db-b478-c0671802252f}
using the following command:
bcdedit /displayorder {263bf496-4ab4-11db-b478-c0671802252f} {0c728e1b-d009-11da-
b18b-9dc1d02cdda0}
You can set a particular operating system as the first entry by using /addfirst with
/displayorder, such as:
bcdedit /displayorder {263bf496-4ab4-11db-b478-c0671802252f} /addlast
You can set a particular operating system as the last entry by using /addlast with
/displayorder, such as:
bcdedit /displayorder {263bf496-4ab4-11db-b478-c0671802252f} /addlast
Changing the Restart Boot Sequence
If you’d like to boot to a particular operating system one time and then revert to the
default boot order, you can use the
/bootsequence parameter to do this. Follow the
parameter with the operating system to which you want to boot after restarting the
computer, such as:
bcdedit /bootsequence {0c728e1b-d009-11da-b18b-9dc1d02cdda0}
Now when you restart the computer, the computer will set the specified operating
system as the default for that restart only. If you restart the computer again, the com-
puter will use the default boot order.
