I've got a 2.4GHZ white non-aluminum Macbook. I was attempting to install Windows XP through the Bootcamp assistant but ran into some major problems. When XP asked me to format the 150GB partition (even though I only created a 10GB Windows partition in Boot Camp), I clicked yes. (just wasn't paying attention I guess) and now I have a non-bootable, 150GB NTFS drive in my macbook. Attempting to boot just gives me a great picture of a folder with a blinking question mark. I booted off the DVD to wipe and reload, but Disk Utility won't let me erase or repartition the disk. It sees the disk but everything is greyed out. Please help!
