no operating system found error

[Phil Dobbin]

Hi,

I've been using Fedora 19 quite happily for a while now but today when I 
booted her I got an error message along the lines of '62: No operating 
system found' & she refused to boot.

I'm guessing it's a Grub problem but I've no clue as to go about doing 
requisite repair work, even after spending an hour Googling the problem.

If anybody could help me out, I'd be eternally grateful.

Cheers,

Phil...
