I just purchased Windows 7 Home Premium Upgrade Family Pack, with 3 upgrade licenses.
I am updating my 3 home PC's from Windows XP to Windows 7.
On 2 of these PCs, I dual boot Windows XP (one for me, one for my wife) on different partitions; both Windows installs activated fine using the same license (probably because they are on the same physical PC with the same hardware, and only 1 instance of Windows XP can be used at a time).
I like to create 2 different partitions, and install Windows on each, and choose which one to start when I boot. This has worked fine in Windows XP. Can I do this with my new Windows 7 Family Pack?
My final configuration would have 1 PC with 1 partition and a new upgrade to Win 7; and 2 PCs each dual booting using the other 2 licenses.
