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...

boot from Fedora DVD or CD, select Troubleshoot, then select Rescue
installed system, when booted enter following commends:

chroot /mnt/sysimage
grub2-install /dev/sda
grub2-mkconfig -o /boot/grub2/grub.cfg

Thanks, Jan. I'll save that for further reference as when I just booted 
it to insert Knoppix/SystemRescue it booted normally, much to my surprise.

I think I'll run memtest though just in case.

Thanks for your help,

Phil...

Also check your power supply and disk cabling. That message is usually
issued by the BIOS saying it can't find a hard disk with a boot sector.
That can be caused by cabling issues or perhaps a power supply that's
going bad.
