Plop boot manager and LVM

[proter4]

I am not able to get Plop boot manager to boot my Linux system that uses LVM and grub2. When I install Plop (using the grub install option) and then I reboot, it isn't able to find the correct boot partition. All I get is "No ntldr" or a missing bootsector error if i try some other configuration. I tried playing around with the partition settings but I couldn't figure it out. Any suggestions?

Here is some info with fdisk -l:

you have to install grub to the linux boot sector before you install the plop boot manager
