Nice! Thanks! Now I will take over your computer lulz!
Guess what? in busybox: (initramfs) cryptsetup luksOpen /dev/sda5 root_disk (initramfs) lvm lvm> vgchange -a y Lap lvm> CTRL+D (initramfs) CTRL+D...and I'm writing to you now! (I don't remember if I mounted something). Anyhow, I can work now, and I will continue to fix this a little bit later. May be it's the part_msdos and the set root='(hd0,msdos5)' that I'm missing.
