OK, I know two different types of hackers:
1. The first type - hackers who have in mind to make dangerous viruses, to make hack tools like WNX - WinNuke eXtended (new name

) or break into big computer systems. All is against the law! Cr4shover, if "computer police" was on this forum - you can be very suspicious for them (IP, NeoTrace etc).
2.The second type - hackers who need to understand how that and that thing work,like disassembling etc. It can be used for good and bad - if you use it for good then you can learn from that code. If you use it for bad, you know what problems may arise.
the os will include (blah blah) exploits,virus maker's
Sorry but you have sick mind. You want to make, ehm,.. "hacker OS"; and you don't know where to start

Well, first thing - a bootloader

Good luck with your "hacker OS"
