I have been looking at migrating my existing Linux O/S to a new laptop but have thought of a possible alternative.
A new laptop would be £850 wheres an HP allin one with a 21.5 in screen is £425. Admittedly running Windows 11S
My 500 Gb, USB HDD is set up so that when plugged into my Linux laptop and the machine is switched on, it boots from the USB HDD. I know that to use an alternate, different laptop that there are UUIDs on partitions that need to be amended using Fstab to reflect the new laptop UUIDs.
Say I plugged into a Windows 11 PC, would it similarly work or would EUFI, safe start and other protectives need to be switched off first?

Re: USB mounted DVD O/S
Since USB is a serial connection running an OS from that is going to be very slow.

I've had mixed results booting full install USB drives on a Win11 machine (ASUS Vivobook) I bought about a month ago. Part of the problem seems to be new security measures (in addition to secure boot). I'm also having trouble with the new machine's USB ports, though, so it's a compound problem and I haven't had enough time for serious troubleshooting.Finston Pickle wrote: ⤴Wed May 18, 2022 8:47 am Say I plugged into a Windows 11 PC, would it similarly work or would EUFI, safe start and other protectives need to be switched off first?
On the bright side, if you're only booting Mint from the USB drive, that seems to work fine.
Don't understand your comment about needing to modify fstab for new UUIDs. If it's a full install USB drive, the relevant UUIDs are on the USB drive and don't change because you boot on a different machine.
FWIW, not bad. Not as fast as an internal drive, of course, but not bad.

USB 3 at 5 Gbps is about the same speed as SATA so a boot from an external USB 3 disk will look the same as an internal disk of the same type, say magnetic vs magnetic. Lots of motherboards have problems where they share two USB ports on one chip and that limits their speed if you use two disks on the same chip.
For devices with internal NVMe 3 or 4 storage, you need USB 3.2 gen 2 * 2 at 20 Gbps or USB 4 with 40 Gbps to get the same speed.
Note that USB 3.0 is sloppy and lets people label incomplete implementations of USB 3.0 as USB 3. Depending on the chip in the USB 3 devices, important parts of USB 3 might work or might not work, making a noticeable difference to the usable speed. I call the faulty chips USB 2.5 and threw out the USB 3.0 enclosures with faulty chips. You can check the devices using the lsusb command. Find their USB ID then search for the ID + Linux.
