Preupgrade problems - got past /boot error

[Thaidog]

So I am trying to do a preupgrade from FC11 to FC12. First I got the not enough room on boot error... which I got by by deleting some older kernels and the grub.efi file. After that the system rebooted and tried to start up a graphical installer... which hung the system. I then booted back in to FC11 and added text to the end of the FC12 preupgrade grub kernel line. That got me to the text installtion method. After that the text install could not find my install.img file so I selected my /dev/sda1 partition which is my boot partition and added the directory where the install.img file is at:

/boot/upgrade/install.img

It then said that the install.img file was not a vailid install file. Everything looks ok with it:

[root@compaq upgrade]# ls -l
total 146588
-rw-r--r--. 1 root root  23540852 2010-03-06 22:00 initrd.img
-rw-r--r--. 1 root root 122544128 2010-03-06 22:10 install.img
-rw-r--r--. 1 root root       276 2010-03-06 22:10 ks.cfg
-rw-r--r--. 1 root root   3423296 2010-03-06 21:57 vmlinuz

Any ideas? I should mention I choose encrypt the hard drive when installing FC11 originally.
