I had set up a machine to dual boot between the Windows 8 Consumer Preview and Fedora 16 for research before realizing that Windows 8 runs just fine in VirtualBox (better than Windows 7 actually, it doesn't even need guest additions!). I now have a VM with the release preview set up; is it possible to get rid of the Windows 8 partitions (main & the system one it creates) and have them be absorbed by the Fedora partitions without re-installing anything?
Your windows partitions are at the beginning of the drive. You can delete /dev/sda1 and /dev/sda2 and create and new Linux partition /dev/sda1 with about 73 GiB.
I take it there needs to be a /dev/sda1? I wouldn't mind absorbing the space (especially into /home, which is where all the VMs sit and is mostly full), especially since I'm not used to keeping data and apps in separate partitions.
You should be able to remove both NTFS partitions if you want rid of Windows.
This is one of the situations where LVM proves its worth though, as adding a new physical volume where the Windows partitions were and extending an existing /home logical volume into it would be straightforward.
Here's what I would do:
1) Delete the Windows partitions.
2) Create a new LVM physical volume in their place.
3) Add it to a new volume group and create a logical volume for /home.
4) Copy as much of the old /home as will fit into the logical volume.
5) Copy the rest to a temporary location in the / partition.
6) Update configuration files (fstab etc.)
7) Reformat the old /home as another LVM physical volume and add it to the volume group.
8) Expand the logical volume containing the new /home to fill the space.
9) Move the files temporarily stored in / back to /home.
An alternative would be to use mdadm in linear span mode (rather than proper RAID) instead of LVM.
