Ok, got the iso (thank goodness for your TB! of junk
It booted the laptop fine, I downloaded the updated installer and ran…I had to use the option --force as it would not overwrite the existing files without.
It is now installing a base xfce system. I do not have a fast connection so it is on 6% I guess it will take another hour or so, at least. I will update after I reboot.
Hopefully the packages are still stored in /var/cache/pacman/pkg or something like that so that I can save them to a pen drive and reuse them when I do an install again later.
Thanks! and All the best
