"Would it work if i just delete the /boot partition
Or would this hurt my linux installation"
Deleting the /boot partition will destroy Linux.
"The only problem now is that i cannot try it until grub is either taken away or fixed. How do i take away grub, and then reinstall it again."
You fix grub by booting into your Linux system, fixing grub by editing your grub.conf file, and then running the grub-install command to rewrite grub to the MBR.
To boot into your Red Hat system boot the Red Hat install CD into rescue mode. When you get a command prompt then issue the following commands. I am assuming that your Red Hat partition is /dev/hda3 and that you have an ext3 file system. Adjust these commands if my assumptions are wrong:
mount -t ext3 /dev/hda3 /pogo
Then edit /boot/grub/grub.conf if it is set up incorrectly.
Then issue this command:
Be prepared. Create a LifeBoat CD.
