I like running Windows on my laptop because I don't do a lot on it and Windows keeps things simple since Windows is the world.
But now I'm wanting to do some development sometimes and I want my Ubuntu dev environment. So I struck on the bright idea to get an external hard drive and load ubuntu on that. Then I can make the USB drive first in the boot order and when I boot, it will boot into Ubuntu.
Then, I unplug the drive and it boots Windows. In theory this sounds great.
My Ubuntu drive is working like a charm, so I unplug it to test Windows boot and it comes up at the grub boot loader in some kind of command state, probably in error.
All the ones I've found on here are for much older versions of Ubuntu. I'm on 20.10.
I tried using Windows bootrec to fix the master boot record, but it just says "Path not Specified."
I have no idea how to fix this, so I'm asking the gurus.
