This is how you can reduce or remove the dual boot delay:
WARNING: MESSING AROUND WITH THIS STUFF COULD CAUSE PROBLEMS. DON'T DO IT IF YOU'RE UNSURE.
1) Go to Start -> Run and type in "msconfig" (no quotes) and click Run.
2) Switch to the BOOT.INI tab. You'll see a "Timeout: 30 sec." option. Change the number of seconds to whatever you like.
3) Press OK. It may or may not make you reboot at that time. Either way, the next time you reboot it should only delay the number of seconds you entered in there.
After looking into that partition i created (what a monster!),
i noticed that it was almost full! From what i can guess, i also installed XP Home on it.
I only want a partition to stock data, i don't need another operating system...
