from Cristian Burneci:
Let's see now...
hda1 =C:\ - primary Windows partition
hda2 = the extended partition with hda5=/, hda6=swap hda7= /home, all logical
partitions
hda3 =D:\ - another primary Windows partition
Now, I wonder why Windows fdisk doesn't allow creating more than *one* primary
partition on a given hard drive. There must be a rock solid reason for this.
At least try and unset the bootable flag of the second primary partition.
(end of quote)
DOS FDISK traditionally doesn't allow creating more than one primary partition
on a given hard drive, and consumer versions of Windows are based on DOS. I
don't know about WinNT/2000, but OS/2 allows creating up to three primary
partitions on a given hard drive if there is one or more logical partition, or
four primary partitions in the absence of logical partitions. Under DOS and
OS/2, only one primary partition on a hard drive can be accessible at one time
(same with Windows including NT/2000?), and I thought that was an inherent
limitation of the hardware until Linux showed otherwise.
