I was reformatting my Macbook Pro (OS X 10.6) and changing over from Parallels to Boot Camp. I partitioned my hard drive and followed the application instructions to reinstall windows xp. All good there. However, somewhere in this process my OS X was deleted. My Macbook now only boots up in windows and when I restart and hold the ALT key, the partition selection tab only shows windows and not OS X.

Please help.

You didn't need to reformat to install Bootcamp.


What MBP are you using?How big is the hard drive? When you are booted into XP, does it show 2 partitions for your hard drive and also how big?

MBP - 2.5GHZ, 4 GB, w/ 250 GB hard drive.

The windows partition is 29.5 GB. I am not sure where to see if it shows 2 partitions.

You can try to put your OSX.6 Install Disk in and run Disk Utility from that.

Or, if you have a backup of your mac from before this happened? Either Time Machine or clone? If so, that would be my next step.

I've tried restarting with the OS X installation cd in the drive, but it still boots in XP.

Can i access the OS X installation CD from XP?

I do have a backup on my timemachine but how do i restore from XP?

Put the disc in and start up the computer and hold down the "C" key immediately to force the pc to startup from the disc.

All good on the startup disk but I get jammed up at this screen that asks you to select the destination disk.

the only option available is BOOTCAMP that reads "At least 24.34 GB free, 31.7 GB total"

the message below this reads Mac OS X cannot start up from this disk

It's been a long time since I used OS X.6, but, before you get to that point, along the top menu bar, you should see Utilities. Select Disk Utility, you should then be able to format your mac startup drive.
