Description of problem: I have been running FC16_64, successfully on my laptop for several months. This is a dual boot configuration with Windows 7, which I hardly use. I just did a Fedora system update that included installing a new kernel (3.2.9-1.fc16.x86_64). The update completed and I rebooted the system. The machine restarted but hangs up with the screen showing only GRUB and a flashing cursor. I booted from the rescue disk and did chroot /mnt/sysimage. I see that /boot/grub2/grub.cfg has been modified to add the new kernel. But I do not see anything obvious that would cause the system to hang. This system obviously is dead. I cannot use Fedora or Windows. It is a real problem because it is my development system and I was in the middle of some important work. Can you please advise how I can get this system to boot? Version-Release number of selected component (if applicable):3.2.9-1.fc16.x86_64 How reproducible: Steps to Reproduce: 1. Start system 2. BIOS loads 3. Observe boot screen hangs with GRUB displayed and flashing cursor Actual results: Expected results: Grub should start and display a list of linux kernels and Windows 7 start options Additional info:
resolved by running # grub2-install --force /dev/sda in the recovery session. I had to use --force because I was seeing a set of warnings: warn: Your embedding area is unusually small. core.img won't fit in it. warn: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are unreliable and their use is discouraged. error:will not proceed with blocklists. I will have to resize partition 1 to start at 2048 to eliminate the use of blocklists.
