Dell keyboard not working when booting Fedora DVD.

[bhunnu16]

I have a Dell Optiplex GX520 Desktop. To install the grub I booted the Fedora 8 DVD, but my keyboard was not responding. I have a USB keyboard as I don't have any PS/2 port. I can't select any of the option.Is there any way to install the grub from iso without using the keyboard in linux kernel.
Kindly tell me the solution.

I think your USB keyboard needs to be enabled from BIOS. Go to bios and there enable the USB keyboard, which will then in turn allow you to choose between bootloaders. This problem was also faced by me, I rectified it using the above method.

Thanks for the reply.
I don't have any option of enabling or disabling keyboard, I only have option to enable/disable front & back USB. Also I don't have the legacy USB support option in BIOS.
