The funny part is that it while the 1024 limit is usually talked about connected with Linux, probably because we update kernels more often then Windows, it can affect Windows when trying to load some drivers, or booting in the safe mode. http://www.serverwatch.com/tutorials/article.php/1489651 http://web.inter.nl.net/hcc/J.Steunebrink/bioslim.htm http://www.educ.umu.se/~bjorn/linux/howto/mini/Large-Disk-4.html Because Karl does not believe in a seperate /boot partition, he was probably bitten by this when upgrading a kernel...
