Mirroring partition table

Well, your question contains great notes on the layout of your disks, so perhaps what you really want to ask is "How can I make certain that the ubuntu installer creates partitions in the right place?"

For that, I recommend...

1. run "gparted" from the live cd before you begin the install. that way, you can shrink whatever existing partitions you need to shrink in order to lay out the disks to your liking. if, for some reason, you need to reboot to run chkdsk on the windows side, at least you won't have wasted time working your way half-way through the installation process.

2. run the install and when you get to the disk partitioning step, choose manual partitioning and instead of modifying the disk layouts at all, just select the partitions you wanted to use and tell the installer where to mount them.

for further reading and better confidence in this process, you may want to do a bit of RTFM as well. https://help.ubuntu.com/community/WindowsDualBoot seems like a good place to start...

The kpartx command will do all the work for you of detecting where the partitions exist and setting up loop devices with the appropriate offsets.

# kpartx -l /dev/ganderData/example-sysdisk
ganderData-example--sysdisk-1 : 0 497952 /dev/ganderData/example-sysdisk 63
ganderData-example--sysdisk-2 : 0 62412525 /dev/ganderData/example-sysdisk 498015

# kpartx -a /dev/ganderData/example-sysdisk
# mount /dev/mapper/ganderData-example--sysdisk-2 /mnt/tmp
