The size of the converted volume might differ slightly from that of the original primary volume,
because some space might be required to store supplementary information.
Caution: Avoid converting the active volume or the system volume to logical. Otherwise, the machine will likely
become unbootable.
You can later convert the volume back to primary—see Convert to primary (p. 45).
To convert a primary volume to logical
1. Right-click the primary volume that you want to convert to logical, and then click Convert to
logical.
2. Click OK to add the pending primary volume to logical conversion operation.
The results of the pending operation are immediately displayed as if the operation had been
performed.
To perform the pending operation you will have to commit it (p. 24). Exiting the program without
committing the pending operations will effectively cancel them.
6.12 Converting a logical volume to primary
This operation applies to basic disks whose partitioning style is MBR. It converts a logical volume on
such disk to a primary volume.
Each basic MBR disk can have either up to four primary volumes, or up to three primary volumes plus
an unlimited number of logical volumes.
You need to convert a logical volume to primary if you want to restore the bootability of a machine
whose system volume was accidentally converted to logical.
If the disk contains more than one logical volume, you can convert a logical volume to primary only
when there are two or less primary volumes on the disk.
You can later convert the volume back to logical—see Convert to logical (p. 44).
To convert a logical volume to primary
1. Right-click the logical volume that you want to convert to primary, and then click Convert to
primary.
2. Click OK to add the pending logical volume to primary conversion operation.
The results of the pending operation are immediately displayed as if the operation had been
performed.
To perform the pending operation you will have to commit it (p. 24). Exiting the program without
committing the pending operations will effectively cancel them.
6.13 Changing a partition type
This operation changes the partition type of a volume—a hexadecimal number that normally
identifies the file system or the intended use of the volume.
For example, NTFS volumes have a partition type of 07h.
By changing the partition type, you can “hide” the volume from the operating system.
