Hello, I have a 2.2 gHz MacBook, and I took out the HD, and replaced it with a bigger one. I placed the restore DVD that came with my MacBook in, and I end up with a grey screen, and then the disc pops out. I have tried powering off with the disc in, and holding C (trying to boot from the CD). I also tried to put in the 10.5 OS software I bought when it came out. it tells me that can't be installed on my MacBook. Currently I have a grey screen, and the restore dvd is in the drive sounds like it's spinning it hasn't popped out. Any tips, or do i just wait or?
