I don't see a problem with extended partition being sda3. You don't need to
have all partition slots filled --- once I had one primary and one extended
partition on my drive (sda1 and sda2), and this usually works without any
I understand the OP has a problem with Anaconda insisting(??) to reinitialize
the partition table of the sda drive, as if the drive was never used before.
Other than the warning that sda3 doesn't end on cylinder boundary, I see
nothing wrong with the partition table above. And I'm not convinced that the
cylinder boundary thing could confuse Anaconda that much.
Since the OP claims that this setup works well with both Windows and Ubuntu
but not with Fedora, my advice would be to burn a Fedora Live CD, boot it, and
do a fdisk -l again to see if Fedora provides some different kind of output.
That might give a clue to what is going on.
For the OP --- during the Fedora installation, are you sure to have selected
"create custom layout" on the partitioning screen of Anaconda? There are
typically several choices there, and if you choose custom layout, you will be
given an option to manually select which partition is to be mounted where,
will they be formatted or not, etc. I guess that is what you want to use, in
order to have full control over the partition layout.
If Anaconda forces you to reinitialize the partition table (ie. delete all
partition information and start from scratch) on a perfectly well-behaving
drive, then it either means there is a serious bug/corner case in Anaconda
somewhere, or that you have a hardware or bios problem.
The above partition table looks completely OK, AFAIK. And I have never seen
Anaconda insisting on reinitializing the partition table except on a brand
new, unformatted drive.
