Problem installing Snow Leopard from external DVD-writer

[caravanya]

Hi everybody,

I've been working on installing Snow Leopard for some time now and I keep jumping on to problems. So I hope for some help!

My internal DVD-drive doesn't work any more, that's why I bought an external dvd-writer (Samsung SE-S084). I have an original Install DVD for Snow Leopard + a digital downloaded file to be sure (which I burned on a DVD).

My computer is a Macbook Pro 10.5.8.

When I try to open the file this appears:


Dutch for: Can't open this file with this volume.

In Disc Utility, the ext. writer + dvd is recognized.

What to do??

What kind of install disc do you have? Is it a retail copy or a grey restore disc?

 

[caravanya]

It's a grey Disc: Mac OS version 10.6, Disc version 1.0

Grey discs are machine specific and won't install on anything but the model they came with originally. You need a retail version.

Thanks, I'll try to get a different version than.
