i installed fc4 from iso images from hard disk. :-)
hi to all,
here is the way i went -
i had fc3 running on my system.
i had all iso images in some directory in a partition which is not going to be formatted in installation process.
(in my case partition was /dev/hda8 and directory was fc4. and /dev/hda8 was mounted at /data)
note down the number of partition which contains iso images.
then issue following commands-
$ mkdir /mnt/tmp
$ mount -o loop /data/fc4/FC4-i386-disc1.iso /mnt/tmp
$ cp /mnt/tmp/isolinux/vmlinuz /boot/vmlinuzMy
$ cp /mnt/tmp/isolinux/initrd-XXX.img /boot/initrdMy.img
then add following lines to /etc/grub.conf
title Fedora Core 4 Installer
root (hd0,6) <<------------ this must be your boot partition
$ /sbin/grub-install /dev/hda
select the newly added option
and it will ask you options like language, keyboard, type of install
here select hard disk and specify the directory containing iso images.
( in my case - it was /dev/hda8 and fc4)
press enter and you are done.
normal installation will continue afterwards.
