SYMPTOMS
After you choose to convert the basic disk that contains your Windows 2000 boot partition to dynamic, you receive the following error message during the required reboot:

STOP 0x0000007B Inaccessible boot device

Note: If more than two partitions were on the drive, rebooting the system may allow you to get past this error, but Disk Management may now report the disk as &quot;Dynamic Unreadable&quot;.



CAUSE
The basic disk contains an unsupported partition type, which may include an OEM diagnostic or configuration partition that Windows 2000 does not support.

The following list shows basic disk partition (System-ID) types currently supported before installing this fix:

Note: The System-ID is used to specify the type of file system that is contained in the partition.  Value   File system 0x01   MS-DOS 12 bit FAT 0x04   MS-DOS 16 Bit FAT 0x05   Extended partition (holds logical drives)(LDM leaves intact) 0x06   BIGDOS File Allocation Table (FAT) 0x07   Installable File System (IFS), for example, HPFS and NTFS 0x0B   Primary  Fat32 Partitions up to 2047 GB  0x0C    Same as 0x0B, uses Logical Block Address Int 0x13 extensions 0x0E   Same as 0x06, uses Logical Block Address Int 0x13 extensions 0x0F   Same as 0x05, uses Logical Block Address Int 0x13 extensions 0x12   Compaq EISA Utilities partition. (LDM leaves intact) 0x84   Used by various manufacturers (Dell suspend to disk partition) 0x86   Windows NT 4.0 fault tolerant partition indicator (FAT-FT) 0x87   Windows NT 4.0 fault tolerant partition indicator (NTFS-FT) 0xDE   Dell Utilities partition. (LDM leaves intact) After you apply this fix (included in SP3 or later), all other unsupported partition types are transformed into a dynamic simple volume except for a type 0xFE, which is an IBM Utilites partition that LDM also leaves intact.
