Hi Antonio Olivares!

I am not sure what you mean.

If you are asking how to get rid of the chainloader then I would say
take a look at the grub.conf in the Fedora 9 partition (likely at
/boot/grub/grub.conf) and copy the boot stanza into your currently
used grub.conf.  To make it the default you can place it in the first
position (current default=0) or change the "default=" setting.

You of course can change the default to be any of the kernels in your
grub.conf by either changing the position of thier stanza or otherwise
pointing "default=" to them.

I see no mention of 2.6.26.5?  I do see several 2.6.27...  I would
guess you are having trouble with the most recent one
(vmlinuz-2.6.27-0.382.rc8.git4.fc10.i686).  If you, for example,
change "default=0" to "default=1" then it will default boot
vmlinuz-2.6.27-0.377.rc8.git1.fc10.i686.

To troubleshoot the boot process press escape during the "splash"
screen.  If it appears to fail at X try a CTL+ALT+F1 (should go to a
tty terminal login screen) and view the contents of /var/log, such as
messages, dmesg, Xorg.0.log, etc...  You may well find some hints of
what is going on.  You can also view these after a failed boot by
mounting the partition where the kernel exists and looking at
/var/log.  Dmesg contains a lot of stuff that happens during boot, and
/var/log/boot.log should as well.

I hope I have been helpful.  Good Hunting!!

Tod
