I did that when I first got into Linux using Zorin, Manjaro, and Ubuntu. Sometimes things were slow, most times things ran fast enough. If you have a 3.0/3.1 USB port it should be a good experience.
I have never used an RST equipped PC. It may be that the kernel does not know what to do with RST type storage. Maybe someone else has specifics on that?
Hi, Thank you for your reply. I knew this procedure. My laptop is critical i don't want to take any risk switching to AHCI and risking Windows corruption. However the RST check should not extend to an external drive, therefor the RST warning popup is a false positive. Even weirder i manage in the past to install an Ubuntu 22.04 on an external drive and i did not had this popup.
Yes exactly it is prior "Something else" (if i cancel at that stage, and open gparted i see the USB Drive). So it is a regression from previous release if i understand well. Thank you !
Re-reading the OP, I believe @MJ2412 mean's the by-pass (work around ) is via using the Zorin OS 15.3 first, then once your setup, then "Upgrade" your external Zorin OS to !7.1. via the "Upgrader".
I assume you keep your data backed up, then try with the Zorin OS 15.3 as the first install to your external.
