Boot manager / How to hide other primary partitions

Hallo

I want to use the boot manager inside partition manager 11 Prof (German)
It works, but ...

How to hide the other primary partitions (C ??

(I use the german version, so I try to transscript it into english)
Boot manager
Boot manager install assistent
###
Configurate / Deactivate
Normal / Hidden modus
Close up

As in the description manual, there should be after B.M. install assistent
a selection betwean (hiding other prim part/option in boot menue)
This point I miss !!

The last hidden modus means only, that is hidding, only waiting for Hotkey


All I want, is to let the other three primary partition hidden and not
see-able by my working system. Only my own C: should be visible and active


So, with other words, where can I select to hide the others ??
1.) Inside the program, when in working system Windows7
2.) When bootet from rescueCD, there should be possible to select hide


Thanks for reading my bad english
Hope, you can help me with a hint
Ludwig

 

Option to hide other system partition is disabled in Boot Manager, because Win7 and Win Vista often are installed with small MSR partition, where boot files are stored. Hiding this partition will make system unbootable.

As each Windows system has its own Drive Letter policy, you can make other system partitions unaccessible by removing drive letters from Windows Disk management.
