JSI Tip 4070. Upgrading the System or Boot drive to Dynamic (Rooting).

When you convert a Windows 2000 disk from basic to dynamic, all of the partition information is stored in a private database at the end of the disk. The MBR (Master Boot Record) contains one type 0x42 partition table entry.

When a disk contains the System or Boot partition, the process, called rooting, is different.

The entries in the partition table are kept intact, but the File System IDs are changed to 0x42 to indicated that they are dynamic. This allows the BIOS to load the kernel and other files required to start the drivers needed to read the dynamic volume.

An entry is added for any unallocated space on the volume.

NOTE: See tip 3027 to convert the disk back to basic.

NOTE: Any disks added after rooting the system or boot drive are lost because they are only included in the private region (database) and not in the partition table.

NOTE: See Q175761 - Dynamic vs. Basic Storage in Windows 2000.
