Your answer looks close to what I was thinking. Regarding step 5. I am considering gddrescue instead of dd. Regarding step 6. My fstab for /boot and /swap or using GUID/UUID's. My lv's are id'd by logical volume names: /dev/mapper/machine_name-lvroot /root etc. Would that need to change?

Just now able to get back to this. boot-repair didn't work it's broken (at least the version for my Ubuntu 10.04 LTS) I want to chainload grub2 from NTLDR Leaving grub on it's own /boot partition and with Linux setting in a LV. All the original Linux partitions are now dd'd into my extended partition. So I need to reinstall grub2 manually? But for this setup I can't figure out how. The partition scheme is: /dos - contains: NTLDR, boot.ini, /ext - contains: windows OS, 3 NTFS data partitions, as well as /boot (grub2) and the LVM2 VG (Linux OS). Any help would be greatly appreciated!

After a considerable amount of research, I finally found the time to solve my problem. I wanted to give you credit for your help and excellent advice. So I'm accepting your answer. I do have a detailed write-up that might be helpful for someone else facing an edge case such as mine. Would it be a good idea to post that here?
