Live without Windows

OK! I hate M$, I don't like Windows, I am a advocate of Linux!
But many external factors cause me to stay with M$, like the Word Document sent by my boss!
Now, my hard drive installed with Windows XP is dead, another one installed with Linux is working flawlessly. So I am now living without Windows! Yeah!

[edit]
!#@$(!@%&#@!(*)*$!@ !!!!!!
The machine craps again! What happened ?! Is it a signal for me to get an entirely new PowerMac G5 ;p
