I’ve “installed”(not “live”) an O.S. to the 2nd partition of this flashdrive. Part.#2 is active, primary with “flag” set to boot. There is no partition drive designation. (i,e. in MSWin something like F, G, etc and in GParted it would need to be sdc2). When I go to either GP or Win disk mgmt, where I need to assign a letter/designation, it’s “.greyed out”. So, I’m prevented from doing what , I think, is needed to get the second part. to “boot”. The first part. is active,primary. I’m missing something, but I don’t know what that might be. Want to get that second partition to be recognized so that it will boot up.
