On basic master boot record (MBR) disks, marks the system partition or boot partition with focus as inactive.
For examples of how this command can be used, see Examples.
- After you mark the system partition or boot partition as
inactive, your computer starts from the next option specified in
the BIOS, such as the CD-ROM drive or a Pre-Boot eXecution
- An active system or boot partition must be selected for this
operation to succeed. Use the select partition command to
select the active partition and shift the focus to it.
