Just the usual of making very sure you know which drive you're copying
to. It doesn't matter what's there, and the iso will just start writing
at byte 0 and continue as necessary.

I've done several of these in the last few days, thanks variously to an
unrecoverable Windows installation and the good old Acer UEFI antics.

I just did dd, no options, and went and did something else until it was
done, as I am doing at the moment.

You may want to check the copy has gone OK:

 sudo cmp -n `stat -c '%s' insert-name-here.iso` insert-name-here.iso /dev/sdX

Adjust the filename and /dev/sd number as appropriate, and yes, you do 
need the name of the iso twice, once inside the backticks and once 
outside.

Don't think so, just pick the graphical expert install from the
advanced options. Are any of your machines using UEFI? If so, the
installer should see that and the opening screen should actually say
'UEFI installer'. There will be a small additional FAT partition 
required if so.
