Maximum PC

I have win 7 on a SSD, I have data, and 3 OS's in 4 partitions on a 2TB HD. I made a small 20gb partition at the end of the HD for Ubantu 11. I used instructions for Linux partitions found here page 51 At the end of the install, ubantu could not install a bootloader on any of the HD partitions. It gave an error. and an option to try other partitions. I tried each. I assume, it was because I put it at the end of the drive. I finished the install with a Ubantu option to complete without a bootloader/grub. I used EasyBCD to add an entry on my boot menu. Of course Ubantu did not load. My boot menu is, Win7-SSD, Win7-HDD, Win8CP-HDD, XP-HDD, Ubantu 11.
I know some about bootloader's, MBR's. Probably just enough to do major damage or worse. My partitions are imaged backed-up.
I know zero about Linux command line instructions. Ubantu dose boot as 'Live' from a USB bootable HDD I made.
Suggestions how to get Ubantu to boot, while keeping all my other OS's working? I know there will be a Linux boot menu after I choose Ubantu from the windows bootloader.
Any help would be welcome.

Simplest way....install it using Wubi?

You could move some partitions around so you have a small, say 100 meg partition on the front of everything so you can install the bootsector and mbr correctly. Kind of a lot of work if you ask me though.

There's a way you boot from the ntbootloader, but you need to be in ubuntu to create a boot file to take over to the windows size of things
