Windows 7 Home Premium Upgrade question

#1
In the past when I've upgraded from one OS to another, I've always had issues down the road so with Windows 7, I only want to do a fresh install if necessary. I found the following info about Windows 7 Home Premium Upgrade from Microsoft and I'm trying to make certain that I understand it, especially the part "ve bolded, underlined, and is in Red.

I have Windows 7 RC on my PC and two drives in Raid 0. If I were to buy the Upgrade, could I delete then recreate my raid (thus wiping the drives clean I believe) and use the Upgrade to do a fresh install?


The following text is from: Installing and reinstalling Windows

"Installing a custom version of Windows. Choose Custom to completely replace your current operating system, or to install Windows on a specific drive or partition that you select. You can also use Custom if your computer doesn't have an operating system, or if you want to set up a multiboot system on your computer."

I just got this reply from Digital River:


"The Windows 7 offered in this promotion is a full version. You can
install this product even though you do not have a previous Operating
System installed in your computer or if you want to make a multi boot
using Windows 7. The "Upgrade" included in the product name is just
because Windows 7 is the latest Operating System Windows developed.
