Not sure about working directly from an optical drive to a thumb drive as I haven't tried that for maybe two years. But what I do know for sure is that I have several different distros installed to USB sticks, each of which boot and run just fine on multiple machines directly from the USB stick, no problems with GRUB. *Usually* I create these in two stages. First, I download the distro iso file, verify checksum (and often signatures) and then dd copy the iso to a cheap USB 2.0 drive to create an installation device, aka a 'bootable USB' or 'live USB'. Second, I reboot the computer into this new 'live USB' and then use the distro's provided installation program to install permanently to a better quality USB 3.0 drive--this to create the final "live USB with persistence". During the install from the first USB to the second USB there is most often an explicit opportunity to specify where GRUB should be installed. This of course is a new GRUB and it should be installed to the second USB along with everything else. Also, when booting into a live USB or the new permanent installation on the second USB for the first time, the host computer boot order device precedence must be reset so that UEFI or BIOS sees the USB before it sees the hard drive and boots into that. Otherwise, you have to interrupt the boot process by hitting F12 or whatever each time you want to boot into the USB, which is annoying. Probably you already know most or all of the above possibly better than I. But I take it from your comment below that there is still something or other that one of us is missing. Also, I'm going into it a little because the subject happens to be a current fetish of mine and I've been trying to develop my knowledge a bit. So I'll continue. When making a "live USB with persistence" there are about a million ways to install the OS and to configure partitions, home directories, GRUB, UEFI/BIOS, etc., -- all of which usually confuse the daylights out of me so that I usually opt for whatever appears to be the most painless default nuke-n-pave option available and leave it at that. But there are two points about which I always make sure I am absolutely lucid because to do otherwise is really dangerous. The first is that I am very certain I am installing everything to the USB stick and not to my host computer hard drive so that I don't destroy my existing system. The second is that I know whether the new installation is fully encrypted so that I don't inadvertently expose any sensitive data or personal information to theft. It is altogether too easy to lose or misplace a USB stick. A couple of months ago Jared of abqlug.com, who was aware of my USB and antiX fetishes, asked me if I might try to write an article for the website because I suggested to him that I thought using Linux installed to USB sticks might be a great way to introduce noobs and wannabes. Here it is: https://www.abqlug.com/uncategorized/getting-started-with-an-mx-or-antix-lin... A bit overwrought here and there but gathers in one place a lot of information that might otherwise be hard to find in one place when someone wants it. If anyone is so inclined please have a look and tell me what you think. Tom On 7/30/20 6:45 AM, Don Crowder wrote:
I've got a copy of Slax on a thumb drive and have used various live media distros on a flash drive to install Linux on machines that didn't have optical drives (or had optical drives that didn't work) but if you install from optical media to a thumb drive then GRUB is gonna want to know where that drive went every time you boot up the machine.

Install to a USB stick. A 64 GB USB 3.0 SanDisk Ultra Flair is ideal. $15 at Walmart. Weighs exactly 5 grams, same as a nickel. Great form factor and mechanically solid: 3/16" x 7/16" x 1-1/4" and you can keep it stashed in your pocket encrypted with all essential records and files for use on multiple machines. Great for testing and experimenting, redundancy, extra space, cheap insurance, etc. Not that I'm a fan of Walmart or that better deals can't be had, but certainly cheaper and less hassle than another computer to worry about.

Thanks, I ran across it, as GNU/Linux OS, a couple of days ago and was curious about it but I don't currently have a machine I'm willing to use for distro-hopping so I did no more than read about it.

Hello All,
I was poking around and looking at a website specifically re: Gnu and the Hurd OS. Hurd doesn't really work much at all but there were 6 OSes listed that were certified FOSS and approved by Stallman. They each used the linux kernel. I downloaded PureOS and installed in as a virtual machine (in the non-FOSS Vbox). After a few tweaks it was up and running and I really like it. I would migrate to it if I had a clue how to keep everything. It's fast and clean, the FOSS browser works perfectly. No issues with sound nor anything else. It's Debian based so its Gnome GUI is very familiar.
Just thought that I'd let you all know.
Ciao
