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@amturing:~]# mount /dev/VolGroup01/LogVol00 /mnt/FC5 [root@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@amturing:~]# mount -t ext3 /dev/hdc1 /mnt/tmp/ [root@amturing:~]# cd /mnt/tmp/ [root@amturing:/mnt/tmp]# ls -l total 5076 -rw-r--r-- 1 root root 58999 Feb 15 15:35 config-2.6.15-1.1955_FC5hypervisor drwxr-xr-x 2 root root 1024 Feb 13 18:08 grub -rw-r--r-- 1 root root 1682973 Feb 24 00:33 initrd-2.6.15-1.1955_FC5hypervisor.img drwx------ 2 root root 12288 Feb 23 18:30 lost+found -rw-r--r-- 1 root root 94600 Feb 8 09:39 memtest86+-1.65 -rw-r--r-- 1 root root 812461 Feb 15 15:35 System.map-2.6.15-1.1955_FC5hypervisor -rw-r--r-- 1 root root 1528756 Feb 15 15:35 vmlinuz-2.6.15-1.1955_FC5hypervisor -rw-r--r-- 1 root root 257054 Feb 15 14:42 xen.gz-2.6.15-1.1955_FC5 -rwxr-xr-x 1 root root 710104 Feb 15 16:09 xen-syms-2.6.15-1.1955_FC5 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 title FEDORA CORE 5 TEST 3 root (hd1,0) kernel /vmlinuz-2.6.15-1.1955_FC5hypervisor ro root=/dev/VolGroup01/LogVol00 rhgb quiet initrd /initrd-2.6.15-1.1955_FC5hypervisor.img # These are the images copied to my main /boot directory # but these are not necessary as I used to boot the old FC4 Test3 # as above. # this line was put after I got the error message but it didn't fix the problem title FEDORA CORE 5 TEST 3 (2.6.9-1.667) DISCO2 /dev/hdc 5000 rpm root (hd0,2) kernel /vmlinuz-2.6.15-1.1955_FC5hypervisor ro root=/dev/VolGroup01/LogVol00 rhgb quiet initrd /initrd-2.6.15-1.1955_FC5hypervisor.img Any ideas what is happening?
