I've 2 hard drive C: and D: on each drive is installed XP professional C: is for Testing apps and bulls**** and D: is for work (very clean). Now i need to hide disc C: from my computer when i boot from D: and viceversa. Is there a way to hide some drive from "my computer"????

Not the billboard (i've already modified it) but the boot screen (black with windows logo and progress bar). I've made my personal boot screen named "mykernel" as described in Cosmetic guide and modified the boot.ini with /kernel parameter but this work only when setup is completed.

I made my custom unattended setup cd, with modified billboard, bootscreen etc.. Now i want to change the boot screen that appear at the first reboot next the copy file process (blue screen). Which file/s i have to edit? Thank
