No, I haven't changed anything recently. I will check
that. It did this once before (apparently by itself)and I
was able to restore my machine with the default settings
in the BIOS. But when I looked for those again, it wasn't
evident where they were. I will look at it again tonight
after work.
At power on hit the appropriate hot key for the BIOS setup.
There are then two common places to look:
in a BIOS settings page, as 'Boot Order (where you use PageDn to cycle
round various standard setups, choosing one that starts C: for the hard
disk)
In a specific Boot Page, where you use the arrows to select the device
you want first, then the + on the number pad to move it up. Again
getting the hard disk to the top.
Either way then ESC to get back from there, and Exit, saving settings
If that then does not boot, something has damaged the hard disk's
initial items - come back and get suggestions
