[FDE] Full Disk Encryption with DM-crypt, system does not boot

Hi,
I wanted to receive a system with FullDiscEncryption
https://wiki.archlinux.org/index.php/Dm … ire_system

METHOD: Simple partition layout with LUKS

I did this:

//sda1 for boot, +bootflag, 300MB,type linux
//sda2 for root, rest, type linux

# cryptsetup -y -v luksFormat /dev/sda2
# cryptsetup open /dev/sda2 cryptroot
# mkfs -t ext4 /dev/mapper/cryptroot
# mount -t ext4 /dev/mapper/cryptroot /mnt

# mkfs -t ext4 /dev/sda1
# mkdir /mnt/boot
# mount -t ext4 /dev/sda1 /mnt/boot

# pacstrap /mnt base
# genfstab -p /mnt >> /mnt/etc/fstab
# arch-chroot /mnt
# ln -s /usr/share/zoneinfo/Europe/Berlin /etc/localtime

// ANPASSUNGEN:
// etc/mkinitcpio.conf
// HOOKS="... encrypt ... filesystems ..."

# mkinitcpio -p linux

# pacman -S syslinux
# syslinux-install_update -i -a -m

# vi /boot/syslinux/syslinux.cfg
...
LABEL arch
        ...
        APPEND cryptdevice=/dev/sdaX:cryptroot    // (root=/dev/sda3 rw I removed this)
       
#passwd
#reboot

Now the system does not boot any more, I'm sure that my fault exists int he APPEND Config File. Any Ideas?

Welcome to the forums, Lucci95. On most of the forums/sub-forums here users are expected to use English as the "official" language; there is another forum (the Other Languages forum) in which you can write in your mother tongue. I am pretty certain we have a number of veteran Archers who speak fluent German. I am going to report this thread to the moderators for moving to Other Languages; you will probably find it and any responses to your query there the next time you log in.

Re: [FDE] Full Disk Encryption with DM-crypt, system does not boot

with

root=/dev/mapper/cryptroot

I receive:

ERROR: Failed to open encryption mapping: the device /dev/sda2 is not a LUKS Volume and the crypto= parameter was not specified.
ERROR: device /dev/mapper/cryptroot not found. 
Unable to find the root device /dev/mapper/cryptroot

With adding:

crypt=::::

  I receive:

Non-LUKS encrypted device found.

A Password is required to access the cryptroot volume:
Enter passphrase:
Verify passphrase:

Error: The superblock /dev/mapper/cryptroot could not be read or does not describe a correct ext4 filesystem.
