Upgrading Win 7 that is freshly installed on an external USB 2.0 HDD
Hello,
I have just installed a fresh copy of Windows 7 Pro (x64) onto an external hard drive (connected via USB 2.0). (I used a freeware program called WinToUSB to achieve this.) It now exists alongside my normal Windows 7 installation (which is on an internal SSD). My goal is to upgrade the external copy to Windows 10 without having it alter the way my PC boots normally when the external HDD is powered off.
Currently, I can switch between the two copies of Windows 7 by choosing the boot device from my mobo or just by turning on the PC with one of the drives disconnected. My hope is to keep it this way (in a "kind of, but not really, dual-booting" scenario).
My plan is to run the Windows 10 upgrade on the external Windows 7 while my internal SSD is unplugged from the mobo (an Asus "P8Z77-I Deluxe/WD").
Will this work as I expect it to? My hope is that there will be little to no evidence of Windows 10's existence when I turn my PC on while the external drive is disconnected (or powered off). Will Windows 10 affect my mobo's UEFI BIOS or anything like that? Basically, my fear is that Windows 10 will somehow insert itself into the mobo or somehow lock me out of booting normally from my SSD. (All I really want to do is test out Windows 10 for a while before I upgrade my normal Windows 7 install.)
Thanks!
