Why is my windows bootcamp on MacBook stuck on loop?

Hello,

I'm having problems with my MacBook Pro 15" system.

I have BootCamp installed on it running Windows. Whenever I try to start it up it goes into a startup loop and stays this way.

I can't press shift or any of the keyboard buttons because the keyboard does not work and the keyboard light does not show.

Also the fan makes a lot of noise when I switch it on. I can only start it up by taking the charger out and holding the power button. I have changed the battery and the charger but still does not work.

I would appreciate if someone could offer some advice.

Thanks

Do you have access to a second Mac system? If you do try connecting your system via a FireWire cable and starting up your system in Target Mode. Once you get there run Disk Utility form the other system to test out your HD. Let us know what you find.

OK, can you create a bootable drive? What I do is get a 16 GB USB thumb drive and prep it up.

First delete the FAT32 partition and create a GUID partition map and a journaled partition using Disk Utility. Then download if you haven't already the Mac OS installer app from the App Store and run it to install the OS onto the USB thumb drive. Once done I would copy the OS installer onto the thumb drive so you'll have it for the future.

OK, now with the bootable drive restart your Mac by holding down the option key so you get the disk manager, select the USB thumb drive as your boot disk and then run Disk Utility to repair both the permissions and disk. See if that flxes things.
