If you've tried installing/recovering Windows from a usb boot drive before (rather than an optical drive) then you might be aware that, sometimes, the boot drive stops working. Windows refuses to boot from it anymore, and you have to recreate the drive for it to work. Is there a way to bypass this by making the boot drive read-only, since I plan to only use it for maintenance/support purposes ?
On that note, I just installed Windows 8.1 on my external (haven't tried it yet, but everything is set). Is there a way to make the boot partition read-only, to avoid similar issues as described above ? Because if I set up an entire system around my external, it would be a bitch to get locked out of it over a silly little change, probably in some obscure .inf file that I couldn't find if my life depended on it.
