I just got my copy of snow leopard in the mail, so I decided to upgrade my laptop. After doing a full backup, I didn't turn out to be as easy as I thought.

The installation process quickly showed a little yellow triangle, indicating I didn't have any startup disks. I quickly remembered I had a dual boot to Ubuntu, and used Refit, which is basically an alternative boot menu, to get into Linux and the likes.

So I looked up the removal instructions, but unfortunately this didn't change the situation. I then read that OS/X will restore the standard EFI loader (if that's the correct terminology), by opening the Disk Utility, and making the partition slightly smaller and bigger again. Trying this I got an odd error, namely "MediaKit reports no such partition". No dice.

So I ended up booting an Ubuntu Live CD, removing the linux ext3 and swap partitions there. After this was done, I was able to resize the main OS/X partition, which eventually fixed the problem.

If you ran into similar problems, I'm hoping there's enough keywords in here for you to find this solution :).

After all that installing Snow Leopard is a bit of an anti-climax. As advertised, not a lot changed, and I've yet to see a noticeable speed difference. The OS is using less disk-space, but 29 euro is still a high price for a glorified 'rm' statement.

I do notice small notification improvements here and there, and Address Book.app now supports CardDAV, which is nice.
