[SOLVED] After preupgrade to fc16, "file not found" on choosing upgrade boot choice.

[StefanJ]

This laptop has been happily running FC14 for a year or so. No compatibility problems.

Yesterday I ran preupgrade. It apparently succeeded . . . no errors anywhere along the way that I could see.

After the long "progress bar" showing installs and cleanup reached the end, the system rebooted.

/boot contains the fc16 kernel, and grub.conf shows the "upgrade to fc16" entry.

When I select this boot entry, I get nothing but a "ERROR 15" "file not found" error.



I can reboot and select fc14 . . . which is how I'm typing this.

I'm at a loss on how to proceed.

Here is the grub.conf:

What logs could I look at that might help determine what went wrong?

Thanks,

Take a look in /boot/grub2 and see if there's a grub2.cfg. If so, you probably need to run grub2-install and start using grub2 instead of legacy grub.

You nailed it. I found what I needed here:

I was knocking my head in looking for a log that might have told me what went wrong in the early boot process. The key was the "ERROR 15" message, which let me do a ore refined search.

Thanks!
