Hello Tango, and welcome to Seven Forums.
I've had pretty good luck with Windows 7 recognizing my RAID 0 array without having to use the F6 option to load drivers
when installing to the RAID 0. If the system image that you created from your old RAID 0 setup had the drivers installed, then I do not believe you should have a problem restoring the image to the new RAID 0 array.
There's no guarantee, so have your RAID drivers on a USB flash drive to be safe in case you need to use the F6 option to load them.
You can use either your Windows 7 installation disc or System Repair disk to do this since you only need to boot into the "System Recovery Options" screen at boot to do the system image recovery.
Do note though that the system image recovery will restore on the new RAID 0 exactly the same way it was on the old RAID 0. For example, if the old RAID 0 was 250 GB and the new RAID 0 is 750 GB, then it will restored as one partition with 250 GB on the new RAID 0 leaving the other 450 GB as unallocated space. Afterwards you can just extend
the 250 GB partition into the 450 GB unallocated space to have all the 750 GB together.
Hope this helps,
