Short version: where did the Reinstall without erasing option go?
A friend's machine has been running 14.04 for almost a year. Some time in the last week or so the keyboard and mouse stopped working. I have tried both PS/2 and USB types and neither work with his current setup. However, it's clearly not a hardware issue because if I put in a Live CD everything works great.
I tried using the "Install Ubuntu" icon on the desktop top, but the only options it offers appear to be Erase the existing install, including /home and all of the installed software.
I have found references on the net (e.g. here) that show pictures where the first option is to reinstall and preserve home directories and installed programs, but an ISO downloaded this morning does not give me that option.
I'm sure I'm missing something obvious.
