MBP won't boot on Snow Leopard but does on Windows XP

[Chicointrepido]

Hi, I hope this finds everyone well.

I have the most weird problem. Suddenly my Mac just wont boot on its OS (Snow Leopard), it is stuck on this blue screen with its spinning wheel.

But when I press the alt key and choose Windows (BootCamp) it does boot. That's how I am able to write this distress note.

This will hopefully mean this not a hardware related issue? Tho I have made no change on my OS, just suddenly happened.

Mm does anyone have any idea of how can I solve this? I have spend one hour on Windows I am already desperate.

Thank-you

Sounds like something within your OSX got corrupted. If have a recent backup, try re-installing OSX. I heavily recommend using the archive and install option so you don't lose your data (but its always safe to have a back up)
