This is good advice in general, but I want to nit-pick one point.

Assuming the "NT Bootloader" in > NT 3.x to < Vista, it does not prevent 
any other OS from booting at all.  In fact, that's just how Wubi works, 
by "chain loading" from ntldr's c:\boot.ini.  It's actually kinda cool 
(I think I heard somewhere that M$ bought that bit of code, which would 
explain it).  Note I know nothing about Vista, but I think I heard it 
uses a different boot loader, so all bets are off there.

E.g., see:

Ntldr can chain to grub or grub can chain to ntldr, it really doesn't 

Having said that, loading Windows first (as is already the case here), 
is easier, as Brian points out.

"Microsoft Tax" = the additional hardware & yearly fees for the add-on
software required to protect Windows from its own poorly designed and
implemented self, while the overhead incidentally flattens Moore's Law.
