HELP Always used 32bits & now i want w7 U 64bits but can't install

i did use the Microsoft USB Tool but everytime it ended with an eror like:
the files are on the drive but unable to make it bootable or something like that.

No big deal i used Rufus instead and i know Rufus works well since i did it in the past to install Win7 U 32b With USB.

i'm not sure i'm following with the "load a RAID driver at the F6 point"

all the keys i can use during boot is:
DEL to enter bios
F8 or F9 to select Boot Priority
F4 i think for recovery options
F6 don't work at all (not when i boot PC and not when win Setup loads)

i can only load drivers when i'm about to install, right before you have to select the disk where you want to install on, where i have the option to select & manage the disks.
thats the only time i can load drivers.

i'm also not realy sure whats the difference to instal to array but yes it seems i'm doing so since it's the only way to detect my Red Cable HDD, at leasts when i use this HDD, now i switched back to my old HDD with large cable, so i don't think this option mathers anymore?

as for my BIOS it's set on IDE now, i didn't tryed AHCI yet, maybe i should try it first and see if it maybe works that way.

What i would want is keep my old large cable HDD with win7 32 bits on it, just like i got my seperate HDD with XP on it, just take them out of the PC, put that that Formated Red Cable HDD in it since it should work faster, install Win7 Ultimate 64 Bits on it.

Why, because in case the HDD should crash or something, i got my 2 seperate HDD left to put in (1 with XP & 1 with Win7 32 bits) so i can at least use my computer if i realy need it but don't have the time to do a clean install with a new HDD.

i know it sounds a bit odd lol but i can't miss my computer even for 1 day since i use it for everything (work , TV , watching movies , games , and most important to comunicate with people i know)

i could also try to disconnect the other drives, didn't try yet, altough i never had to do it to install windows in the past.

i also could try the cmd prompt & maybe i could manage everything with it instead of having limited options in the windows setup menu.

i'm also wondering since i'm not using my optical drive, should i disconnect him to?
it's using 1st Slave (large cable).

i checked the RAM on both XP & win7, bios tells 4GB installed & OS tells 4 GB installed & 3.25 GB useable.

Seems like x64 is a strange lil beast to handle

oh ok i see well if i can get it to install then i'll keep it in mind.
for now i will try once more with complete formated and unpartitioned HDD & AHCI and see what it does, if that don't work, i'll wait a few hours till i get the DVD i requested from a friend and try to install trough DVD instead of USB, maybe that will help idk.

Anyway, when you you look at my MB & Proc.,
MB: Asus M2N SLI-Deluxe
Proc: AMD Athlon 64 x 2 Dual Core 4800+

it means it support x64 right?

Ok i finaly found the problem lol
i'm running Win7 x64 now btw

HDD with Red Cable has a jumper on it but not like old HDD, i got 2 settings to put on:
- SATA 1 = 5 Gb / sec. Partial
- Blank

It was set on Blank so i putted it on the SATA 5 Gb / sec.

In Bios :

i could choose between :

- IDE
- RAID
- HDCI

i've taken HDCI.

Saved Changes in BIOS & Exit.

When i rebooted, i pressed F10, to Use the RAID Detect Option and Configure it.

First i removed the ARRAY i created in Mirror,
then i recreated an ARRAY in STRIPE, Cleaned Disk, Saved Option and ReBooted.

Boot from USB, everything loaded untill i had to choose to install either Upgrade or Clean Install.

I choosed Clean Install but i still had the same error like before:

"windows was unable to create a system partition or locate an existing Partition ... blablabla ... lol"

i pushed on back button and used Recovery tools, Used the Command prompt to Format Disk from there without any partitions, then i tryed to install again but same error again.

Then my brain started to realise that maybe i should jump on my other computer and search for other RAID Drivers, so i did, seaeched for ASUS RAID Drivers x64, i putted them on my USB with the Windows instalation on it, then i putted my USB back on my "Dumb Computer" lol, at that point my windows install screen was still open, i clicked on "load drivers" , selected the ASUS RAID Driver, once loaded, i clicked "install" again and ...
YEEEEEESSSSS !!!

It started to install Win7 x64 !!!

It took like 3 to 4 min. to completely install and reboot.

So i'll keep this in mind for the next time.
Follow These Steps:

- Make USB bootable Drive with Win x64 on it
( i used RUFUS instead of Microsoft USB Tool)
- Add the right RAID x64 Drivers on your instalation USB with Win 7 on it.
(For me Asus RAID x64 Drivers)
- Check Jumper on Red Cable HDD, put on SATA 5 Gb/s.
- Disconnect any External HDD & Optical Drive if you don't use it.
- ARRAY = STRIPE then Clean, Set on Boot & Save.
- BIOS = HDCI then Save & Exit
- Boot from USB
- Format HDD and Create only 1 main Primary Partition (the whole HDD) with Command Prompt.
- Select Clean Install (Not Upgrade)
- Select HDD you want to install on (but don't click "Continue/Next" yet)
- First click on "Load Drivers", Select ASUS RAID x64 Driver & Load it.
- Now you can click on "Continue/Next" and watch the installation progress.

Hope this helped for Asus users & thanks to all of you for the advice given.
