grub cannot load /vmlinuz-2.6.15-1.1955_FC5hypervisor kernel image

[Alberto Patino]

This will be a long post sorry!

I have two disks hda and hdc, hda is loaded with WinXP, FC3, and FC4,
all of them are
bootable from grub, grub is installed in hdc3 by the way.
My second disk had FC4 Test 3 so I thought it was time to test FC5
Test3, so i downloaded
the iso images in hda, (I used the hard disk installation method), as
I did with FC4 Test 3.

Every time I use the hard disk installation I dont install the grub
loader, and I used to
edit the grub information later  directly in my grub.conf file.

To make things fast I just created the boot partition in /dev/hdc1
and a volume manager partition to hold the / filesystem and swap
in /dev/hdc2:

Disk /dev/hdc: 40.0 GB, 40007761920 bytes
255 heads, 63 sectors/track, 4864 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/hdc1   *           1          13      104391   83  Linux
/dev/hdc2              14        4864    38965657+  8e  Linux LVM

I selected ALL the packages to install, by the way I didn't find a
global option to
select all the packages, so it was a ugly to have to select the
packages by groups.

Well the installation was fast, so it was the moment to update the
grub information
to boot my new FC5. I booted to my FC4 system, and I checked the / installation:
1- I mounted my LVM logical volume with the new FC5 installation:
(VolGroup01 is the volume group created by FC5 Install)

[root at amturing:~]# mount /dev/VolGroup01/LogVol00 /mnt/FC5
[root at amturing:~]# ls /mnt/FC5
bin   dev  home  lost+found  misc  opt   root  selinux  sys  usr
boot  etc  lib   media       mnt   proc  sbin  srv      tmp  var

2- I mounted /boot partition from FC5 to copy the names of the kernel images:
[root at amturing:~]# mount -t ext3 /dev/hdc1 /mnt/tmp/
[root at amturing:~]# cd /mnt/tmp/
[root at amturing:/mnt/tmp]# ls -l
total 5076

I noted that there was no standar image kernel here, as i read release
notes and I
suppose that hypervisor is related with xen vmm.
Besides the initrd-2.6.15-1.1955_FC5hypervisor.img it has the date of
my installation.
With all this new stuff for me I just move to pass 3:

3. I updated my grub information, and booted my machine.
The result was annoying Im getting the error 13 from grub:
Error 13: Invalid or unsupported executable format.
I Thought I wrote something wrong in my grub.conf file
so I enter to grub interactive mode:
> root (hd1,0)
> kernel (->)TAB and I saw the FC5 kernel images... so I chhose one
but the error 13 is there

Part of my grub.conf:
# This was for using installation disk method
title INSTALL FEDORA CORE 5 TEST 3
        root (hd0,2)
        kernel /vmlinuz
        initrd /initrd.img
# The kernel images are in /boot mapped to /dev/hdc1

        root (hd1,0)

        initrd /initrd-2.6.15-1.1955_FC5hypervisor.img
# These are the images copied to my main /boot directory

Any ideas what is happening?

Thanks a lot for your attention
