Problems with installing Arch on encrypted drive

Hello again!

I am now trying to install Arch Linux on my AA1L machine, with encrypted root partition. I have /dev/sda1 which is the unencrypted boot and /dev/sda2 which is the encrypted / partition. I followed the ArchWiki article which explained me to have 'encrypt' in the HOOKS variable of /etc/mkinitcpio.conf. However when I boot, GRUB gives me "/dev/mapper/root not found". Any ideas what did I miss?

Boot with a live cd and show the output of 'blkid' and the relevant (last) part of your grub menu.lst (from sda1). And perhaps also mkinitcpio.conf, minus the comments.

Hi,

sorry about my English .

I think you must change menu.lst  from /dev/mapper/root to /dev/sda2 ?

I have on my acer laptop no problem.

On my book: / an /home are encryptet.

Re: Problems with installing Arch on encrypted drive

you should not "just have" the hook in /etc/mkinitcpio.conf. It should be at the correct location (eg just before "filesystems")
Don't forget to rebuild your initcpio with mkinitcpio if you change settings in /etc/mkinitcpio.conf.

And also what Funbird said.

Both of these things are nicely documented @ http://wiki.archlinux.org/index.php/LUKS_Encrypted_Root, btw
