Partition/ File system Description |
42H |
Windows 2000 Dynamic Extended Partition Marker
(If a partition table entry of type 42H is present in the legacy partition table, then Windows 2000 ignores the legacy partition table and uses a proprietary partition table and a proprietary partitioning scheme (LDM or DDM). Pure dynamic disks (those not containing any hard-linked partitions) have only a single partition table entry, type 42H to define the entire disk. Dynamic disks store their volume configuration in a database located in a 1-MB private region at the end of each dynamic disk.) |

Boot-US boot manager
(Boot-US (Ulrich Straub) boot manager can be installed to MBR, a separate primary partition or diskette. When installed to a primary partition this partition gets the ID 45H. This partition does not contain a file system, it contains only the boot manager and occupies a single cylinder (below 8.4 GB). ) |
