I have a server that I accidentally installed the 32 bit version of FC17 on instead of 64 bit, and which is now located remotely. The server is a Dell Poweredge 2950 with a DRAC card installed, so I have remote console access. There are two additional logical hard drives in addition to the one on which the current OS is installed. What I am trying to figure out is if/how I can build a bootable installation media on one of those other hard drives and then use it to reinstall the OS? This would save me a 100 mile drive to install CD or USB installation media.

A couple of notes: 1) The DRAC does give me BIOS level console access, so I can reboot the box and choose boot options, etc. 2) I guess what I really need to know how to do, that I don't know how to do presently, is take an installation .iso and "burn" it to a hard drive instead of to a CD/DVD.

I haven't done this for awhile. This method doesn't need a local installation media but a connection to the internet. Please be careful and consult other sources.

First you need the two files (vmlinuz and initrd.img) and put them in the directory /boot.

Possible source: ftp://mirror.switch.ch/mirror/fedora/linux/releases/19/Fedora/x86_64/os/isolinux/

The next step is to modify the grub menu. The example below show the entry for a previous releases of grub not sure if it's still working:

title Installation Fedora 19
root (hd0,0)
kernel /vmlinuz askmethod
initrd /initrd.img

After a reboot you should see a new entry in your grub menu.

Couple of options. Easiest one would be - create Fedora installation on an USB stick and send it there asking somebody to put it in. Then you can reboot and proceed with re-installation.

Second option could be via Grub. It is possible to configure Grub in a way that it possible to boot from in - see here:

Haven't done that. Put the ISO on a partition which you will NOT re-format (e.g. /home) otherwise it will not work. Good luck.
