Perhaps someone can explain what is going on here because I can't see how this can't be a bug. 1. Take Fedora Core test 1 disk 1 and copy the contents to a tree on your hard disk. 2. Burn a cd from that tree in the normal way and boot from it. 3. Select a custom install and then untick all packages (this will make it install from just this one disk and not require any of the other three). 4. You will notice that everything works fine, it installs and no problems booting after. NOW: 5. Using the tree of disk 1 from point 1. above. 6. Run genhdlist to regenerate the hdlist and hdlist2 files in the base directory. 7. Burn a cd from the tree in the normal way and boot from it. 8. Select a custom install and then untick all packages (this will make it install from just this one disk again). 9. You will notice that everything seems to install fine but when the system reboot it will not boot with a File not found error from Grub. Grub is looking for vmlinuz in the /boot partition but I have connected to the installation using a rescue disk and the /boot partition is missing several files such as: vmlinuz-xxxxx initrd-xxxxx.img and some others. How can regenerating the hdlist from an unchanged disk1, doing an install that only uses disk 1 cause this failure? Nick
