True partition hiding for Windows 2000/XP/2003/Vista/2008/7/8/10
All Windows versions from Windows 2000 and higher ignore the simple hiding of partitions, i.e. those partitions are still
visible to Windows. In order to hide a partition under Windows 2000/XP/2003/Vista/2008/7/8/10 the partition must
be true hid. When a partition is true hid the partition ID and the boot sector of the
respective partition is modified. True hiding a partition is available with Boot-US 1.5.0 (or higher).
If Windows 2000 up to Windows 10 is involved and multiple independent installations of Windows are to be
performed, the present partitions must be true hid before the next installation is carried
out. The true hidden partitions are ignored by all versions of Windows.
It is possible that Windows 2000/XP/2003/Vista/2008/7/8/10 considers a true hidden partition as unformatted.
This can be changed by removing the drive letter from a true hidden partition. This prevents that you
accidentally format such an "unformatted" partition thereby deleting all existing data
on that partition. Drive letters are assigned or removed within the Windows disk administrator (Computer Management / Storage / Disk Management).
