I used the preupgrade option to upgrade from fc7 to fc9. But while rebooting, it reports that it is unable to find the stage2.img file and asks to select the location where the ISO image is present. I am still able to boot in to fc7 and when i do that, the stage2.img file is seen in the boot/upgrade folder. Is some thing wrong with anaconda or is it not possible to upgrade in this manner? I would like to either upgrade it or to get rid of the upgrade option itself. Can you suggest something?
