Re: Dual boot Issues
Check the partition. There should be something on what to boot into. Check a different computer and see if it works there. Has it booted successfully before? Or has it just never gone past BIOS? if worse comes to worst, I would have to say you have no choice but to format it and try again. You might want to try a different partion method, if possible, in the future.
Macbook Pro and Logitech z5500s. All you really need.
