Dual Boot

[satimis]

Hi,

Fedora 17 64bit

I installed Fedora 17 on a HD which is running Ubuntu 9.04, 64bit. The HD has not been running for sometimes sitting on the shelves. It is a SATA3 HD with 1T in size and 32M memory. Ubuntu 9.04 only takes up about 100G capacity of the HD. I performed following steps to install Fedora 17 for testing Cloud.

- running Fedora 17 live on USB
- selecting shrieking existing OS to get space for installation
- installation completed without complaint
- running yum update

Now Fedora can start up without problem. But I can't resolve how to boot Ubuntu 9.04. Please help. TIA

If I made wrong steps installing Fedora 17, is there any way wiping it out to start again?

B.R.

I think Ubutun is NOT on LVM. This is a spare HD which have been on shelves for sometimes not being used.

You probably installed Fedora's bootloader in the MBR thus overwriting the Ubuntu bootloader.

/dev/sda1 * 63 1495039999 747519968+ 83 Linux

That's a 748 GB Linux partition. Smells like Ubuntu ;-)

Now you can either add Ubuntu to the Fedora boot menu or boot Ubuntu from a recovery media and re-install the original Ubunto bootloader into the MBR.

or boot Ubuntu from a recovery media and re-install the original Ubunto bootloader into the MBR.

Which recovery media? Thanks

Booting the recovery mode only boots Fedora 17

just see if you have os-prober installed. If it is running # grub2-mkconfig -o /boot/grub2/grub.cfg should be enough to find ubuntu by GRUB2. But if it doenst do it, I don't know what else to look for.
