I plan to use : dd if=/dev/hda bs=512 count=1 2>&1 | grep GRUB dd if=/dev/hda bs=512 count=1 2>&1 | grep LILO to check the bootloader I have. I am really new to arch linux, but I want to fix that problem. It seems I almost fix the problem, just solve the lilo and grub-common problem. If I reinstall arch linux, that could be more difficult for me, and I am afraid of losing my data in the system.

Give up with this installation. Reinstall Arch from an up-to-date installation media, and follow the beginner's guide. I think you will learn more by doing this than trying to fix your current installation. Regards, WorMzy
