Keep us posted, if you don't mind.I found a solution to eliminate the undigestible variables and I'm just testing it.

My previous method may have been flawed. I used to simply extract one straightforward image from the disk by use of nLite. I am aware that this has changed other aspects of my bootable installation disks. Among the noticable changes was the loss of the repair option, which I missed dearly.
So perhaps Howie's way is better for me. I had some difficulties to heck his description but now it appears that I have got it.
EDIT: I'm installing Win7-64 on my SSD RAID0!!!!!!!!!!!!!!!!!!!!!!!!!!
It also told me that my BIOS is not suitable but at least it started to install. It broke off in the last minute when it should have restarted the computer. Perhaps I will be able to work around that issue. I'm starting it again and will manually shut down if that is the only way to make sure it restarts.
keep the fingers crossed, please puuuuuleeezzzzeeees.
Good luck.
