Re: [PLUG] Dual booting Linux and Windows

Yikes... that's surprising.  Worrying about properly powered USB ports should not be a think in 2020 (though I confess I did purchase an inline USB power dongle last year so I could check such things after having concerns about some Chromebooks at the time).

Glad you got it working.  For what its worth... these days instead of dual booting, I just wipe Windows (or capture an image of it first), install Linux and then run Windows in virtualization.  I'm so rarely in Windows personally that it hasn't been worth it for at least 5 years now.  I know that's not the case for everyone but having M$ stuff virtually provides me with the ability to test things safely as well as manipulate user bare metal imagines.  When Windows get corrupt or blows up generally, its a 15 min burn-in plus another 5 minutes to create the user's account on computer.

I only mention that to say, if you ever want the reverse of what you are doing (i.e. Windows guest / Linux host) that probably can work for you too and it is not hard to do.

Walt, et al,

Got it. It was the stinkin' USB port. The drive is powered by the USB port.
Perhaps on this machine, only one port is a high power port capable of
driving it. The other ports see the drive, but can't mount it.

As it happens I've also been experimenting with virtualbox this week. One
thing you could try is to mount the drive in Linux, then make it a shared
folder from the virtualbox UI.
