Re: That triggered a memory...
...of a usenet post I once read that went something like:
"I'm a computer nerd and do tech support for all my friends and family, but I've never installed Windows. How do you get Windows95 onto the hard disk if there's no operating system?"
Queue vast quantities of righteous derision - everyone has to learn sometime, but this particular user chose his words rather poorly...
(nb: this was before bootable CD-ROMs, when you had to make a bootable floppy with CD ROM drivers. Or install Win95 from floppy disks)
