I tried to set up a dual boot of windows and linux from
the installer. The linux part works, but windows 7 starts to boot
and then takes me back to grub.
I am sufficiently happy with linux that I was planning to get
rid of windows. I would like to use the space to give openBSD a
try.
As a first step, I tried using cfdisk -Ps /dev/sda, and got the
ominous warning:
FATAL ERROR: Bad primary partition 2: Partition ends in the final partial
cylinder
Since linux is working, I'm worried that trying to fix whatever this
problem is might wreck my system.
fdisk -l /dev/sda gives:
