Do not use lvm, but standard, and either ext4 or xfs partition formats.
I highly recommend sticking with LVM as you have in your F26 installation if you are dual booting with Windows. It would be far easier to expand both the Linux and Windows file systems later on. With LVM you can expand the volume group from the end of the drive
and leave un-partitioned space after the Windows partition for its expansion.
For example on a 250 GB SSD you could have partitions such as
2. 1 GB /boot ext4
3. 60 GB LVM PV
4. 60 GB Windows 7
129 GB unallocated
If you wanted to grow your LVM file systems you would create a new LVM PV partition at the end of the drive
. For example create a 20 GB partition from 230-250GB, format it as an LVM PV, add it to the volume group, and then expand your Linux file systems. The space from 121 GB to 230 GB would be free for either expanding Windows forward or the LVM VG from the back.
If you wanted to grow your Windows partition to install Windows 8 the space in front would be free. You would expand your Windows partition the normal way expanding forward while growing your Linux LVM VG from the back. If you ever ran out of space you would do so in the middle. This is something you can't do with regular partitions. Regular partitions are easier to create but much harder to expand later as you deal with fragmentation. You can only expand a regular partition if there is free space in front of it. LVM allows physically separate partitions to be transparently merged into a single file system.
