Hi, I can reinstall the system any time, but I can learn more when trying to fix the problem. Thank you very much!

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. > > > > > Renzhi Cao > > Email : rcrg4@xxxxxxxxxxxxxxxxx > > ________________________________________ Well, obviously you're going to make backups before you go about messing with highly sensitive parts of your system, especially when using dd, right? And take my word, and the word of every other Archer for it: If reinstalling by following the *Beginner's Guide* is too difficult for you, the previously posted, advanced update guide will be much harder, and Arch is likely not the right distribution for you.
