Hi,

It seems that things are more compilcated than I thought.
I recommend that you will backup the data to another USB disk
and restore them after clean install of F15.

I think you can boot with previous F14 kernel
if you change the following to grub.conf

[1] Change the following line

default=1
to
default=0

[2] Comment out the following 3 lines with '#'

#title Upgrade to Fedora 15 (Lovelock)
#kernel /upgrade/vmlinuz preupgrade repo=hd::/var/cache/yum/preupgrade ks=hd:UUID=68c84152-0834-4e6d-b680-067752edc827:/upgrade/ks.cfg
#initrd /upgrade/initrd.img

Good luck.
