Have been using Linux and dualbooting over more than a decade, yet still, the mere sight of the above screenshot gives me the creeps or shivers. While not as serious as a surgery room decision, since my student days I have always struggled with giving advice or instructions on dealing with the master boot record, and it has gotten slightly more complex since Windows 7 with UEFI and recovery partitions. Here is a decent Ubuntu tutorial which works pretty much the same as Bodhi as both use GRUB2: https://help.ubuntu....indowsDualBoot
From what I am seeing, you are doing it correctly and iirc, Windows XP does not carry the UEFI dilemma hence you are probably safe just installing GRUB2 and letting it override the Windows MBR. Yet, I am no longer confident of owning such advice since if I were you I would just back up all the data, install Bodhi whilst completely removing all NTFS or FAT32 partitions, and completely dispense with Windows XP by now. If you still have a recurring need of Windows XP and you possess the CD or ISO image, a better way is just installing Sun Virtualbox in Bodhi and running a Windows virtual machine off the linux OS. Just my two cents.
