Macbook pro : error loading operating system

So my problem is an interesting one. This was setup with bootcamp with xp and oxs 10.4 originally if I recall correctly. So I went to go back into the mac side and it failed to boot. I couldn't find my boot cd for some time so she sat. Then I found a 10.5.1 disk and she'd boot with it but couldn't mount the hard drive for tests or anything. I was able to wipe the drive and then mount it. But doing so wiped my mac partition, and the disk I was loaned wouldn't do the install so I went down to the mac store to buy brand new copy of now leopard... Got home and the drive don't recognize it. There is a dvd drive in this macbook pro, and I can through in an xp cd and it reads it fine but the funny thing is that now it also will no longer read the 10.5.1 disk I used to get to disk utility before. It just kicks it back out. So anyone got any ideas? It will read an xp boot installation cd. But not a brand new snow leopard or even the older 10.5.1 disk it was just reading fine. Thanks again in advance for help.

macbook pro, Mac OS X (10.6.3), 4gb ram

You need to locate your System DVDs that originally came w/your computer. You cannot use System DVDs from one mac to another because they are _*machine specific.*_ More than likely, it is probably the reason why the retailed purchased DVD did not work.



You can get replacement System Install & Restore CD/DVDs from Apple's Customer Support - in the US, (800) 767-2775 - for a nominal S&H fee. You'll need to have the model and/or serial number of your Mac available.

well I was going to get a replacement of the original disk from apple when I spoke to tech support but rather than wait 3 days for the disk I took my quote into the apple store and showed them the quote and they got me a disk sold it to me for 29.00 for snow leopard and it don't work. So your saying that the cd apple just sold me won't work in my apple mac book pro? The disk I borrowed was only to attempt to get to the disk utility. Which I was able to.... So I picked up the disk I bought yesterday and it don't work. So what take the disk back to the mac store or what? I'm confused. I know that the disks are coded for the laptop they came with but that's for installation generally from my experience not diagnostics and such though. Please correct me if I'm wrong.

So can you clarify this for me? Are you telling me that it's not possible for me to walk into the store and purchase a newer updated version of osx and install it on a dead machine? That the only way is to now return my store bought copy and recall apple again and have them ship me snow leopard and wait for 3 days to be able to fix my laptop? Are you serious?

Apple Stores and AASP do not sell and/or keep in stock System DVDs that _originally came w/your computer._ They are only available through the phone number I previously provided.



System DVDs have the OS that is shipped w/the Mac from the factory. Which OS was on your computer when you purchased it?


In your original post, you mentioned Leopard quite a few times.
