"1) install boot camp
2) partition 15gb for windows
3) put in the windows vista cd
4) reboot
5) start install
6) goto the partition menu once instead and delete the 199mb partition
7) choose the 15gb partition to install
8) let it all install...took forever
9) on reboot, i got an error about winboot.exe or something, so i reboot, and held down "C", which let me boot from the cd
10) i did a system repair, which detected that something was wrong w/ the partition, which i fixed.
11) reboot again, and it worked successfully."
So hat es bei mir dann auch funktioniert. Wichtig: die 200-MB-Partition beim Vista-Setup löschen, sonst wird es leider nichts (2 vergebliche Runden hab ich so vorher gedreht ...).
