Hi Ralf;

That depends on the bios of that motherboard.  I have been forced to 
create and use a /boot partition as the FIRST patition on the disk by 
bios limitations, the reasoning being that most installers put the boot 
stuff on the disk last, presenting the spector of having the stuff 
needed to boot, too far into a big disk that particular bios never 
dreamed about, so the bios disk read calls needed to boot it, can't 
reach it, too far into the disk.

That to me is the usual suspect in case it will install, but not complete 
the reboot after the install. I have a machine about to go out to the 
landfill thats a great machine for linuxcnc, except for 2 problems, 
first being that I had to do that to make it boot after the install, but 
the 2nd problem was that nice & faster than stink AMD multi-core cpu was 
a family 15 build, which had a halt bug, and was one generation too old 
to have the firmware micro-code patch capability.  And it was halting 
forever, needing a power switch power down reboot to bring it back to 
life, and for that use, an absolute killer because it may leave the 
machine moving when it went away.  Very dangerous to the machine if it 
hits mechanical stops, or to any meat that gets in the way...

That HD was moved to an off-lease Dell Dimension 745, and is running 
great.

Cheers, Gene Heskett
