I have a dual boot laptop that was built by Dell with Windows/Red Hat. The grub configuration says that it was made by Anaconda.
The partitions are as follows:
/dev/hda1 Dell Utility /dev/hda2 Windows 2000 /dev/hda3 extended (presumably Windows) /dev/hda5 Linux [\] /dev/hda6 Linux Swap /dev/hda7 Linux [\home]
The bootable partition is /dev/hda2, the Windows partition. I get that the Dell Utility partition is booted by the BIOS, so I can ignore that.
What I don't understand is how Grub (which is located, I assume, on hda5, which is where its configuration files are) is starting when the machine boots, since it must be booting /hda2, at least according to the BIOS.
