Got it! Found the deb package for it here
http://packages.ubuntu.com/intrepid/i386/os-prober/downloadNow i have a new issue....
LVPM moved ubuntu from sda1 (primary, contains vista, ntfs) to sda2 (ext). I have sda3 setup as a swap. It installed the grub loader, and told me to boot and choose ubuntu.
When i rebooted and chose ubuntu from grub, it said "Could not mount partition" and took me back to grub. None of the options work except for vista. Ubuntu either says failed to mount or file not found.
When i choose vista the windows boot manager comes up and shows vista and ubuntu, which i assume is normal because it did that before. I just have to set that not to show up.
But how do i fix the mount issue with grub?
