Help! Lost my Dual-Boot!

Hi all,

I have had RH Fedora running nicely for about a week now and I am very happy with it (except for a wireless networking problem - see thread in the wireless network forum).

I have today had to re-install Win98 (It lives on on physical hard drive and Linux lives on a second drive). Of course it wiped out my Grub dual-boot loader.

Is there any way for me to get it back without having to re-install Linux all over again?

Thanks in advance

Hate to say it but it has to be reinstalled. GRUB looks for other OSs and allows them to load once selected. Windows boot loader only works for Windows so Linux must be reinstalled to overwrite that Windows boot loader.

Sorry. I had that problem several times after I had to reinstall WinXP. I gave up and just use Linux. No viruses.

If you have a bootdisk for your RedHat distro then just put that in and boot to RH and re-install Grub to the MBR. No need to re-install a whole OS just because one program gets wiped.

Do you re-install Windows whenever IE takes a dump, wait don't answer that, bad analogy.

Or you could put your install disc1 in and boot with it and use the rescue feature to re-install Grub if you don't have a bootdisk.

Thanks rberry88,

But.... sigh... just too late... I'm halfway through the second disk of the re-install.

Oh well. I'll put it down to experience. Not too much lost because the system was only a week old anyway and I had not done much to it yet.

For future reference however, what should I do? - I do have a boot disk - but it simply passed me though to the log-on screen (so at least I could get at Linux...) and I also tried booting from the distro CD which took me into the install program. Taking the "upgrade" option noticed that I didn't have a boot loader and allowed me to create one, but as there was no actual upgrade required, it simply did nothing (including NOT creating the boot loader). That left me with only one option (I thought) - a fresh install.

I don't plan on reinstalling Win anytime soon - but what should I do if I have to?

Many thanks in advance.

If you have a CB burner, you can make a rescue cd. Many of the kernels are too big to make a rescue floppy.

The command is mkrescue --iso. This will produce a rescue.iso file that you can burn to cd.
The command is on Mandrake and debian linuxes. Im sure its also on Red Hat.

You do not need to reinstall the OS
For future reference on reinstalling grub.

Boot the 1st CD to rescue mode. Your / will be mounted at /mnt/sysimage
chroot /mnt/sysimage
