Changing Grub config at boot to prevent Kernel panic
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-
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?
