You didn't lose the boot loader, you just misplaced it.  We don't know what 
your expression "I edited the bootloader with seemingly all combinations" 
means.  I sure would like to see your /boot/grub/grub.conf file.  But here 

1.  Boot from your floppy into Red Hat.
2.  From a root shell run:  grub-install /dev/hda
3.  Observe the output by grub for any errors or warnings.
4.  Make sure you have an entry in /boot/grub/grub.conf for XP.  Something 
like mine (your partition number may vary, hd0 is the first IDE drive, 1 is 
the second partition on the drive, grub starts with 0 for the first 
title UNLinux
        rootnoverify (hd0,1)
        chainloader +1
5.  Most RPM kernels from Red Hat will place an entry into the grub boot 
loader config file.  See if that is the case with yours.  If not, add an 
entry for your favorite kernel.

6.  Reboot.  Have Fun
