[Hampshire] Booting 3 distros.

2012-07-04 Thread Clive Woodfine
I have Ubuntu 10.04 and 12.04 on the first hard drive of my desktop
machine. I thought I would try Fedora 17 so I installed it on the
second hard drive and had it boot from that drives MBR not wanting to
risk not being able to boot the other two. I thought Grubs os-prober
on the first drive would find Fedora. It does not.

Any suggestions on how I can boot Fedora. I tried Super Grub Disk and
Plop Boot Manager but they also don't find it.

I had a problem where grub2 on Ubuntu woudln't find Centos installed on 
a separate partition.  It turned out that Centos used LVM for its disks, 
but I hadn't used that on Ubuntu.  As soon as I installed the LVM 
libraries on the Ubuntu (apt-get install liblvm2app, as far as I can 
remember), grub found Centos.

Thanks Simon. I have LVM2 installed though it does not include
liblvm2app, in fact that is not listed in Synaptic. If I run the
command lvdisplay the boot partition on the 2nd. drive shows up okay.

I ought be able to get to Grub on the 2nd. drive with chainloader but
have been unsuccessful.
