HELP - installing VISTA from a USB Stick that was made on a XP machine???


In Runtime
ok, i've built a new rig that has a ASUS P6T WS PRO mobo, no cd-burner and one SATA HDD. plus other stuff but its not relevant here.

i'm trying to install winVISTA ULTIMATE using a KINGSTON TRAVELER 16gig usb stick and have tried the following....

googling and reading 40+ articles.
formatting the USB stick using the HP tool (this is done on my winXP Pro SP3 machine)
formatted to both FAT32 and NTFS (at different times to test it)
then i did this...
# Here i am assuming DVD drive as G and Pendrive as I.(Change it accordingly).
# Now type G:CD BOOT
# Now type this command BOOTSECT.EXE/NT60 I: to update your USB drive with bootmgr code.

then i did this...
followed by copying the Vista DVD content to the USB stick with this: xcopy d:\*.* /s/e/f e:\.

have tried using the USB stick on each of the 10 usb drives on my mobo, but no go.
i CAN get into BIOS and did change the boot order to the KINGSTON TRAVELLER.

the ERROR MESSAGE is... insert a boot device and hit any key...or something along those lines.

my info has come from these main articles...

is anyone can help out at all, i'd be VERY APPRECIATIVE :) totally want to use my new rig :)

ps, i noticed that the USB STICK partition is NOT ACTIVE and unfortunately i can't mark it as ACTIVE in the computer manager. could this be an issue???
