Thanks, @Sascha,
do you mind my asking for a little help? The thing is I already have the Qubes on my USB but trying to figure out how to make it into a rebootable USB.
I downloaded Qubes onto the USB already but the Qubes I downloaded is an .iso file given that I use Mac. Also, the USB I have has considerable storage capacity but isn’t one that is formatted out-of-box for rebooting. I looked into it and as far as I can tell I need to reformat it so that Debian can read it? The next step would then be to have the Qubes file placed on there after it’s been so formatted?
To me that means erasing everything on it, formatting it by using the disk utility application to MS-DOS (FAT) and then I have to set the scheme to GUID Partition Map, and once that’s been done, I just click on erase?
But then if that’s the case and it will work for debian (those are instructions I found for Ubuntu from Mac) then after that do I simply put the Qubes file on there and then once I start my Librem up, hit f2 and then use the BIOS to boot from the USB stick?
Thank a bunch(!), it’s just I’m not sure how to go about it and would rather not spend the extra money if I don’t have to, since chances are if I go out and buy a USB stick I’ll end up getting one I don’t really need.
