Installation of Snow Leopard and Triple Boot(Windows + Windows + Snow)

[IMAyNeed]

I hope this question has a place in windows 7 forums; if not, forgive me.

I have a ASUS G72 with Intel Core 2 Duo P8700 2.53 GHz.
I have one HDD and 4 partitions in it(c is windows 7 home premium x64, d is windows 7 ultimate x64, e is empty and i am planning to install snow leopard on e and f is just my important files.).

my dvd writer seems to be only compatible with dvd + r dl.

i have a 8 gb microsd (SD) card.

as i said, i want to install snow leopard on e: and i want to have triple boot (windows 7 home premium x64, windows 7 ultimate x64 and snow leopard).

simply, just with a windows pc (notebook that is), how can i install snow leopard by the 8 gb SD or by dvd + r dl and how can i make a triple boot?

Note: Snow Leopard Installation DVD is 6 GB so it requires a DL DVD if being installed from DVD, the thing is -for some reason- people are advising DVD - R DL.

I see several things wrong here:

1. You're hard drive is what many, including me, would call over-partitioned.
2. There's absolutely no reason to set up a multi-boot system with the same OS (Two Windows x64 installs).
3. OSX can only legally be installed on a Mac, so these topics aren't allowed on forums like these.
