So I need to run some Windows programs for work and would like to avoid carrying around a second laptop. Space is a premium on my MBP, so my idea is to load Windows onto a thumb drive and boot from there, and work from my MBP. I'm not worried about booting in and out; once I'm in work mode I'll be in the Windows environment for most of the day. Here's my Catch-22. I have a mid-2010 MBP that does not support Windows 10. I have Sierra as my MBP OS, which only support Windows 10. Going backwards on my MBP from Sierra isn't an option as I have multiple Apple devices, all synced and working nicely together. Last thing I want to do is make a mess of my systems. Any suggestions that will get a Windows OS onto my MBP?
