CHMOD: How do I get my Linux back?
This is a really simple question, but I remember I could bring an installation of Linux back from a Windows takeover by using CHMOD under a boot in Recovery Mode. It does this by reinstating Grub or Lilo back to the MBR as it was prior to the introduction of Windows, allowing the existing OS to boot. What were those arguments again?

chmod ??? ??? ???

I don't recall ever hearing of anything such as you describe.

The process of getting grub back to the MBR is much easier than that.

Use your Suse installation disk. Put it in the cd/dvd drive and boot up. At the menu, you should have an option to boot from the disk. Select that and boot from the Suse installation.

Once booted up, run /usr/sbin/grub-install to put grub back into the MBR.

What about Fedora? I'm not sure what may be easier than one command though. It may be CHOWN instead of CHMOD. I remember I did it before a couple times with that one command.

You should be able to boot with fedora cd1 and at the boot prompt enter "linux rescue".

Once booted run:
chroot /mnt/sysimage
/sbin/grub-install /dev/hda

This should put grub back on the mbr.

That's basically the same thing that bigrigdriver said in his post. In rescue mode you need to do the chroot, or you can just use the install cd to boot into the full OS and skip the chroot part. The important command there is the grub-install, that's what's actually reinstalling grub on your MBR.
