Windows Vista installed

SYMPTOMS
If you use Microsoft Windows XP to create a new partition on a computer
that has both Windows XP and Windows Vista installed, the partition that
hosts Windows Vista may disappear.

CAUSE
This problem may be caused by a error in Logical Disk Manager. If the
partition that hosts Windows Vista was created during the installation
of Windows Vista, a 1-megabyte (MB) alignment boundary is created on the
partition. This alignment boundary differs from the alignment boundary
that is created by Windows XP. Therefore, when you use Windows XP to
create a new partition, the different alignments may cause this problem.

WORKAROUND
To work around this problem, do not use Windows XP to create a partition
on a computer that also has Windows Vista installed.
