I want to be able to play around with drivers and updates without putting my primary work in danger so I want to add ubuntu 14.10 to the possible OSes I can boot into.
I already have windows 7 and ubuntu 14.04 installed and use the windows bootloader as my primary.
I reduced the size of my last partition and made room for the third OS (ubuntu 14.10). Booted from my usbstick and installed ubuntu 14.10 using "something else" as an option. So my partitions (viewed from the 14.04 system, but after the install) look like this:
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Number Start End Size Type File system Flags
1 1049kB 524MB 523MB primary ntfs boot /dev/sda1
2 524MB 211GB 210GB primary ntfs /dev/sda2 /mnt/windows
3 211GB 1000GB 790GB extended
5 211GB 211GB 599MB logical ext4 /dev/sda5 /boot
6 211GB 261GB 50.0GB logical ext4 /dev/sda6 /
7 261GB 361GB 100GB logical ext4 /dev/sda7 home
8 361GB 385GB 24.0GB logical linux-swap(v1) /dev/sda8
9 385GB 922GB 536GB logical ext4 /dev/sda9 /mnt/shared
10 922GB 923GB 999MB logical ext4 /dev/sda10
11 923GB 943GB 20.0GB logical ext4 /dev/sda11
12 943GB 1000GB 57.6GB logical ext4 /dev/sda12
I went back into windows and ran EasyBCD to add a new entry to the windows boot loader. I selected the equivalent of /dev/sda10. When I restart the machine I can select the third OS (Ubuntu 14.10), but it brings me to my previously installed 14.04 OS.
If I look at /dev/sda10,11, and 12 (they are mounted under /media/...) it looks like sda10 has a grub folder and the files I would expect, sda11 has the installed OS, etc.
How should I proceed?
Can I edit the grub2 from 14.04 to add an option to select the 14.10 OS? Do I have to start over?

sudo update-grub
That will add the entried for the new install. I do not know nor suggest EasyBCD. It uses the very old grub4dos and forces you to install grub to a partition. Grub2 does not fit into a partition and it converts to blocklists or hard coded addresses which are unreliable. Make sure you have a working live installer to repair grub on grub updates. You can create manual entries to boot the partition which saves having to update grub in first install when second install updates. help.ubuntu.com/community/MaintenanceFreeCustomGrub2Screen
