Pulling my hair out on a disk with both Windoze & Linux partitions which wouldn't boot. Fixed the problem for the boot partition straight away. After that, grub seemed to find the Windoze partition on its own.
SUPERB!! Won't want to miss this CD ever again, which, as it looks, must have been filled up with data to the brim. Even a high-quaiity CD is *extremely* sensitive to any kinds of dust particles. CD will boot anyway, but if you press ESC you will get lots of ugly "sector xxxxxx I/O error" messages. So make sure you use a JEWEL-CASE for this CD! it seems to require every atom of silicon to be readable in order to work reliably for keeps.
Boot-Repair-Disk is awesome. I keep a copy of it on me most of the time and it has helped me and friends on several occasions. Every Linux user should keep this around
It did the job perfectly!
Another success for the boot-repair-disk today! Awsome tool!
