Can I install Windows 8 on a USB Flash Drive?

by markw10 - 3/17/13 7:45 PM

I own an Acer laptop that is runing Windows 7. I love Windows 7 and finally made the move from Windows XP but I really like Windows 8. Yet I'm nowhere near ready to make it my only OS. I know one possible option is a dual boot system. If I need to go that route I may be posting again in the future to find out how I can make a dual boot Windows 7/Windows 8 system. Yet I like trying different OS's and already have two USB sticks that are ChromeOS and Ubuntu Linux. I purchase 4GB flash drives and buy the fast drives.
The question is is it possible to install and then boot from a Windows 8 USB Flash Drive? If so, how would I go about doing this? Also, what is the minimum size USB Flash Drive that could be used? I want at least some room to work with and install apps but it won't be my primary OS. If it's not possible to do this how would I go about making a dual boot system? Already I have a 500GB HD with Windows 7 installed but I believe I'd have to repartition and hope to avoid having to reinstall Windows 7 since I have so many installed apps.
Thanks for help with the above.
