Please Help! Vista install error

My gateway p-6860fx has worked fine for the last few weeks. Yesterday I installed a second hard drive (both the same). I enabled raid in the bios and restarted with the vista install disc gateway gave me. During installation i get this error message:
"windows cannot open the required file d:\sources\install.wim. Make sure all files required for installation are available, and restart the installation. Error code: 0x800700D"

Gateway techs are idiots, and have no clue what it means. I spoke to 8 different techs and got 8 different solutions. One tech even told me the p-6860fx doesn't support raid. Several of them think it's the hard drive and i'm telling them it isn't since the hard drive work several hours ago, and the D drive recovery partition is long gone since i set up the raid vollume. My guess is that i have a bad install disc from gateway.

Does anyone have any idea what is going on?

Also i've hear it said that i can use any copy of vista for my install as long as i type in my product code. Is this true?

Thanks in advance!!!

your dvd disc is scratched or dirty.

install.wim is a windows installation image (installation + windows + image)

I think this is the gui installtion used by vista's installation routine

 

I've ordered a new disc through gateway, I hope this one works. But unfortunatly it's gonna take two weeks :-(
