I think I am getting closer. I tried the suggestion of running 'yum update kernel' while in rescue mode on the second machine. It seemed to work, but it still would not boot. I put the drive back in the original machine, and it booted ok. The problem with X freezing seems to have gone away, so I will use it in this machine as originally intended. However, I would still like to complete the exercise of getting it to boot in the other machine. (Aarhg, I spoke to soon! I just tried it again and it has frozen. However, that is a topic for another thread ...) I ran 'yum update', which updated 53 packages. As mentioned I had previously run 'yum update kernel'. The kernel now seems to be 2.6.27.7-134.fc10.i686. However, uname -r still shows 2.6.27.5-117.fc10.i586. What is the official way of finding out which kernel is running? I ran mkinitrd on the original machine, just to see if it would work. If I type 'mkinitrd -v /boot/test.img 2.6.27.7-134.fc10' (without the .i686), I get the message 'No modules available ...' If I include the '.i686', it works, and creates /boot/test.img. I don't know how to tell it to use the new image. Is there a way to change boot options without booting off the intstallation dvd and selecting 'rescue mode'? I did boot in rescue mode, and tried 'initrd=test.img' and 'initrd=/boot/test.img', but in both cases it said it could not find test.img. You mentioned modifying grub.conf, but I do not have a grub directory in /boot at all. There is an an entry in /etc for grub.conf, but it is a link to /boot/grub/grub.conf, so it cannot find it. I then moved the HDD back to the second machine and booted in rescue mode. This time 'ls /boot' did show the contents correctly - the previous problem where it did not seem to be mounted has gone away. I ran mkinitrd and it worked, but I still don't know how to tell it to use the new image. I tried saving '/boot/initrd-2.6.27.7-134.fc10.i686.img', and then copying 'test.img' over it, but when I tried booting normally I got the original <div class="Ih2E3d">error message - Volume group "VolGroup00" not found Unable to access resume device (/dev/VolGroup00/LogVol01) mount: error mounting /dev/root on /sysroot as ext3: No such file or directory </div>I suspect that I am closer, and my problem now is that I don't know how to tell it to use the new image. Hopefully someone can give me a nudge in the right direction. </blockquote><div> What does rpm -qa --queryformat "%{NAME}-%{VERSION}-%{RELEASE}.{ARCH}\n"|grep kernel|sort return?
