Upgrade from Fedora 14 or 15 to Fedora 16 with
preupgrade leaves bootloader in previous configuration
link
to this item - Bugzilla: #737731
If you
used the preupgrade utility to upgrade
from Fedora 14 or 15 to Fedora 16, the bootloader configuration may have been
left in its previous state. This was due to preupgrade not recognizing that
anaconda cannot 'update' the bootloader configuration in such an upgrade, due
to the migration from grub to grub2 that should occur as part of the upgrade.
This would result either in the system attempting to boot with a Fedora 14
kernel, or failing to boot entirely (depending on whether the
previously-installed kernel is still present following the upgrade).
This
issue was fixed for Fedora 14 in the updated preupgrade-1.1.10-1.fc14
package and for Fedora 15 in the updated preupgrade-1.1.10-1.fc15
package. To ensure you do not encounter this issue, check that you have at
least this version of preupgrade installed before upgrading to Fedora 16.
