Unable to install GRUB in /dev

[Ingens]

Tänkte inte på att sidan var svensk. Men ja.

Hello. I've tried to install both windows and ubuntu for days now. Several hours a day. I've used both google and youtube to try and get me throught the problems on the way. Now I had enough, I'll just make a post and hopefully get some help since browsong others' questions, obviously ain't doing the trick.

Problem:
Unable to install GRUB in /dev/sdb

When I try to install Ubuntu 12.04 on my macbook (2007), I get this error. I use an USB, and I don't use "swap" because I don't know what it is and what I read, it seems it's not necessary and don't have anything to do with my current problem.

This problem occurs in the installation process (at about 70%), I tried shutting it down, re-formating my USB, and do it all over again, with no success. Same problem.

I appreciate help here. I really want to get going with Ubuntu Linux.
