[nflug] Grub Error 18

[Timothy Domst]

I use Parallels on my MacBook for Windows, and apparently Parallels  
works better with an .iso instead of a regular system on a real  
partition.  Maybe if you boot directly into Linux the way you have  
been doing, but for Linux under Parallels use an .iso, if you can  
spare the hard drive space.
