 ====Random halts Mint 19.3 on hp 8540w====
+[20210109] This may be caused by the Nvidia graphics card in the machine.  Recently I've found that using a lower resolution on the monitor prevents the halts and graphics issues.

+====Virtual Box with Windows====
+===You have bootable Windows 10 USB and want to run it in Virtual Box on Linux===
+(Thanks Bob Primak)\\
+I found this hint online:\\
+"VirtualBox itself does not support booting from a USB device. In order to boot from a USB device, another bootloader is required."
+"The easiest solution is to copy the contents of the USB key into an iso file (well, next time I'll just download the iso on the right machine, no USB key needed in the first place)
+<code>dd if=/dev/sdc of=myusbkey.iso</code>
+And then add this .iso as an optical drive in the VirtualBox settings, under Storage, Controller: IDE (or SATA, I guess).
+No need to make a .vmdk file, VirtualBox supports .iso files."
+All of this is from the thread here:\\
+https://askubuntu.com/questions/693719/how-to-boot-from-a-usb-drive-in-virtualbox
+So the answer seems to be, convert (copy) the USB drive to an ISO file and run the ISO as a VM in Virtual Box.  VB can run ISO's as VMs, but it cannot run USB Flash Drives as VMs. (I don't know if it can reach out to USB hard drives or SSDs and use them for VMs, but it looks like it cannot do so.)

 Once you have installed these packages, go to file manager and click on the USB disk again to mount it. There is no need to replug the USB. It should be mounted straightaway.

+====Installing DaVinci Resolve in Linux====
+A frustration for me as I don't have a machine I can use for Linux that has a working nVidia board.  I've tried on a hp 8540w repeatedly without success.  This machine has a nVidia FX 1800 that's just not good enough.
