If you are installing Ubuntu (10.4 or higher) you will run into a problem: OS Selector can not find the installation and therefore you cannot boot into Ubuntu with OS Selector.

Some posts on the internet claim, that OS Selector cannot detect Ubuntu's own boot program Grub2. That is not completely true.

Just wanted to report, that OS Selector (latest version 11 build 3.034) can detect and boot an Ubuntu installation that uses Grub2. Even though Ubuntu itself is only talking (during its installation) of Grub, the actual "version" of Grub being installed is Grub2 (with Grub2 not only being an update to Grub but a almost complete rewrite and therefore acting differently than Grub).

If you are having problems, here is what I did:
1. Install Ubuntu with the root partition (the "\" partition) as a primary partition
2. Make sure that Grub2 gets installed to the ubuntu root ("\") partition. This can be selected in the last installation step if you select "advanced". If that one cannot be selected install it into the MBR of the disc containing the Ubuntu root partition.
3. After install boot using "Super Grub2 Disc"
4. In a terminal window perform "sudo update-grub"
5. To write into the boot sector of the root partition (necessary so OS Selector can find the Linux OS), perform "sudo grup-setup /dev/sdXY - -force" where sdXY has to be adjusted to the corresponding root partition (use "sudo fdisk -l" in the terminal window to find it out).
6. Reboot and check that OS Selector finds Ubuntu

If ubuntu has already been installed:
1. Boot Ubuntu using Super Grub2 Disk (if Ubuntu cannot boot by itself).
2. Install Grub2 to the partition: sudo grub-install --force /dev/sdXY
3. Reboot and check that OS Selector finds Ubuntu

The "Super Grub 2 Disc" step is necessary because otherwise it can be difficult to get the installed Ubuntu to boot (as OS Selector does not find it) - so it is used as a kind of jump start support.

This procedure helped me to get Ubuntu installed and detected by OS Selector on two totally different systems. Many steps where gleamed from other posts in this forum (especially from Mudcrab's postings).

One of the main problems I've had with the later versions of Ubuntu is that GRUB/GRUB2 does not actually install when you tell it to. I tell it to install to the Ubuntu partition (root) and it goes through the steps, fails, and reports nothing. Ubuntu does not boot correctly by itself (OSS isn't even in the picture at this point). I've had to resort to installing GRUB manually to fix this, though I've always used the Ubuntu Live CD and not the GRUB/GRUB2 CD.

Once GRUB is correctly installed and working, OSS generally doesn't have a problem finding it.
