Can't boot to Fedora after clean install over upgrade

[tron_thomas]

I have a MacBook Pro 5,1 and by using a boot loader called rEFIt I've been able to boot the system between Mac OS X, Fedora Linux (64-bit), and Windows 7.

I recently tried to upgrade my Linux installation to Fedora 15. The upgrade had some problems so, I decided to do a clean installation. I told the installation process to install over the previous version o Fedora.

Now when I go to boot the system, I get a new option in the boot loader in addition to the original three options I had before. If I select the original option I used to boot into Linux, I get this error message:

No bootable device -- insert boot disk and press any key

If I select the new option (called Boot EFI\redhat\grub.efi from EFI) I get a grub prompt. I do not know what to do at this prompt that would allow me to boot into the newly installed Fedora system.

What can be done so I can properly boot into Linux from the boot loader on this system?

On your previous installation of Fedora, did you have a separate /boot partition? Did you install Fedora 15 to the same partitions you had for your earlier versions of Fedora? Do you now have a separate /boot partition for Fedora? Did you install Grub to the Fedora /boot or / partition?

I'm not sure if I had a separate /boot partition on the previous installation. I'm guessing I did not. I do not know if the new installation was made to the same location as the previous location. During the installation process, I selected the option that said to install over the original version. I don't know if the new installation partitioned things differently then they had been before. I did not do anything special to install grub. I assumed the installation would configure grub.

How can I determine the way my new installation is partitioned?
How can I determine where Grub might be installed?

Sorry, I can't answer your questions. You are using the Mac bootloader to access Fedora and I've never used a Mac. You are able to boot your MacBook Pro, correct? I would thing you have some utility like fdisk to get partition information.

I can boot into Mac OS X. I suspect I can also still boot into Windows, only I have not tried that. It appears that my version of Mac OS X (10.6. does come with fdistk. However, I suspect the diskutil command is probably more appropriate for this system. Here is the output I get when I run diskutil list:

/dev/disk0
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *320.1 GB disk0
1: EFI 209.7 MB disk0s1
2: Apple_HFS Macintosh HD 106.5 GB disk0s2
3: EFI 524.3 MB disk0s3
4: Microsoft Basic Data BOOTCAMP 106.7 GB disk0s4
5: Linux LVM 106.2 GB disk0s5

Your output from the Mac shows a Linux LVM partition but no separate boot partition. I'm not familiar with the Mac utility so I don't know what that means.

If you still have the Fedora Live CD, run the fdisk -l(lower case Letter L in the command) from a terminal logged in as root. Post that output.

[tron_thomas]

Unfortunately, the live CD did not work for me. Even though the computer was able to boot from the drive, Fedora would not run, and I was left with a garbled screen.

[yancek]

Is this the same Fedora CD you used to install? Strange that it suddenly stopped working. Anyhow, I have no other suggestions since I'm totally unfamiliar with Macs. Good luck with it.

I burnt a DVD of the full Fedora installation, not just the limited live installation. I had to run the setup in a basic video mode to get the installer to work. If I tried the normal way of running the installation it would fail to initialize the hardware properly. I think a similar problem with video hardware initialization occurs when running the live version. I am going to see if I can get the live version of a different distribution to run on the system. Hopefully I can execute a command that will be able to explain how the system is set up.
