thank you
Appreciate the advice but both my optical drives (or rather my IDE controller) packed in a few months back so will need to use a USB solution if any exist.
It's not a priority anyhow as it's back home on the other side of the country and no longer in regular use by me, it's just not fair having to talk to family members using the PC on how to reboot from the command line since a hard reset ends up disabling the USB devices (keyboard included) causing GRUB to keep selecting Ubuntu
