Creating Bootable Partitions
Before creating a partition where you plan to install an operating system (a
bootable partition), you should understand the information outlined in the following
table.
* Windows NT must boot from a primary partition on the first drive. However, only a few NT files must
reside on that partition; the remaining files can reside on a logical partition, which can be located on
the first or a subsequent drive. The NT boot partition can be shared with another operation system.
Additionally, NT must be installed on a FAT partition. During the installation, you can convert the
partition to NTFS.

ARNING
:
When you create, move, or resize a bootable partition, the partition must
begin below the boot code boundary specified in Table 11 in order for the
operating system to boot. With the exception of DOS 6.22 (or earlier) and
OS/2, partitions beyond 8 GB are visible to the current operating system.
For more information, see “Understanding the BIOS 1,024 Cylinder Limit”
and “Understanding the 64K Boot Code Boundary” in Basic Concepts in
Help.
PartitionMagic displays a warning if you attempt to create, move, or resize a
bootable partition outside of the boot code boundary. If you continue with the
operation, you may not be able to boot or to see the partition. In either case, you
can resolve the problem by moving the partition back within the boot code
boundary. In most cases this is not a problem. Always create an image before
changing your configuration.
