Atapi cd install :???????????

Alright , I had this problem previously, and fixed it both times eveuntully. My problem is this , I can't install my Windows Ultimate 64 bit edition on my RAID 0 Western Digital 500GB hdd's because on the boot screen my computer keeps telling me to "Reboot and select proper boot device or insert boot media in selected boot device" , ive done both those instructions, rebooted , reinserted, all of it , no solution , i made sure my boot priority is the drive first, and raid drives after. still nothing. but this is the intresting part, last time i fixed this problem by using my previous computers dvd drive to install instead of the blu ray , it installed and everything was right with the world. BUT i have since then thrown out the old DVD drive, and now have nothing to install with.

So what i did in the past hour was used a freinds DVD drive to install , and it did not work. ,

When my System Config , is set to RAID, it calls both my blu ray and his dvd drive, ATAPI CD, when in IDE, it calls my blue ray a blue ray , and his dvd drive a dvd drive. I dont understand what is going on , i simply want to do a clean(custom) install of my windows 64 bit on my two RAID 0 HDDs, ive checked the boot priority , ive put both hdds in RAID0, and ive also used someone elses dvd dive to try and install , what is going on , please help. soon , im missing my games LOL... ( I am 14, so please excuse the poor spelling or grammar in this post),

I have no experience running a RAID configuration, so I don't really have a solution to the problem.

Have you tried installing from a usb flash drive? Here's a useful tutorial on how to do so. I prefer method two in the tutorial. No third party software is needed.

i dont have a USB drive large enough for a (20 GB OS)...

Are you wanting to reinstall from an image backup, or from a Windows disc?

disc . too my RAID 0 hdd's. i belive it has something to do with that my BIOS keeps recognizing my Blu Ray as an "ATAPI CD" , and when in IDE mode, it Recognizes it as a BluRay

If you're simply doing a clean install from a Windows 7 installation disc.

A 4gb flash drive is large enough to copy the contents of the disc on to.

I have a blu-ray , and

IDE Mode (Not What I Want) = Plextor Blu-Ray & Working Installation

RAID Mode (What I Want) = ATAPI CD & Please Insert Boot Media Message/ Not Working Installation

Problem is my whole family (Except me thankfully) uses mac computers , im typing on a mac, and the only USB i have access too and will be able to have access too , is a 2GB usb... , how will i burn my iso. of the original 64 gb disc to a 2gb USB on a mac, even if a usb install works , please explain in detail whats wrong with a simple boot from disc, and how a 20GB Os gets into a 2gb usb stick!? (Please i know its not on the list of things to do for you to explain something in detail to a 14 year old lol)

and another thing i recall the second time i had this problem with my clean install of windows "Alright , I had this problem previously" , that i already tried the usb method. doesnt that mean that my one free iso. burn ticket for microsoft is done, arnt u only allowed to use the iso. to burn once?
