Changing Grub config at boot to prevent Kernel panic

Hi all,
I need to change "sda" to "hda" in my grub conf file. This is because my hard drives are plain IDE and not SCSI. Since I have sda in by grub conf file, the kernel goes into panic mode and reboots after 60 secs when I try to start the machine.
In order to change "sda" to "hda", I boot the machine and hit "e" on the selected kernel. On doing so, I see the following lines-
root (hd0,0)
kernel /vmlinuz-2.4.27 ro root=/dev/sda3 vga=extended panic=30
I then select the second line and hit "e" to edit again. On the Grub Edit line, I change "sda" to "hda" and hit enter to go back to the previous screen. When I boot from this kernel, the changes are not saved and the kernel again goes into panic mode.
Any ideas on what I'm doing wrong here?

instead of going back to the previous screen just press 'b' to boot once you've made the change
