Имеется домашний ноут, на котором установлена Ubuntu 14 + KDE, диск разбит на LVM-разделы.
Задача: установить Arch Linux, оставить /home и восстановить dual-boot с Windows.
Диски и разделы:
[simterm]
[root@archiso ~]# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT loop0 7:0 0 365.4M 1 loop /run/archiso/sfs/airootfs sda 8:0 1 14.6G 0 disk ├─sda1 8:1 1 476M 0 part /run/archiso/bootmnt └─sda2 8:2 1 64M 0 part sdb 8:16 0 596.2G 0 disk ├─sdb1 8:17 0 2G 0 part ├─sdb2 8:18 0 16G 0 part ├─sdb3 8:19 0 500G 0 part │ ├─kubuntu_vg-root 254:0 0 30G 0 lvm │ └─kubuntu_vg-home 254:1 0 470G 0 lvm └─sdb4 8:20 0 78.2G 0 part sr0 11:0 1 1024M 0 rom

Тут /dev/sdb — это жесткий диск ноута, sdb3 — LVM разделы с root и home Ubuntu, а sdb4 — Windows-раздел.
Установка системы
Форматируем старый root:
[simterm]
[root@archiso ~]# mkfs.ext4 /dev/kubuntu_vg/root
mke2fs 1.43.4 (31-Jan-2017)
/dev/kubuntu_vg/root contains a ext4 file system
last mounted on / on Wed Mar 8 15:03:14 2017
Proceed anyway? (y,N) y

Монтируем его:
[simterm]
[root@archiso ~]# mount /dev/kubuntu_vg/root /mnt/ [root@archiso ~]# ls -l /mnt/ total 16 drwx------ 2 root root 16384 Mar 8 15:19 lost+found
[/simterm]
Устанавливаем систему:
[simterm]
[root@archiso ~]# pacstrap -i /mnt/ base base-devel ==> Creating install root at /mnt/ ==> Installing packages to /mnt/ :: Synchronizing package databases... core ...
[/simterm]
Монтируем /home:
[simterm]
[root@archiso ~]# mount /dev/kubuntu_vg/home /mnt/home/
[/simterm]
Создаём /etc/fstab:
[simterm]
[root@archiso ~]# genfstab -U -p /mnt >> /mnt/etc/fstab
[/simterm]
Проверяем:
[simterm]
[root@archiso ~]# cat /mnt/etc/fstab | grep -v \# UUID=827fdd05-0506-4056-bdf8-a816b5afc47f / ext4 rw,relatime,data=ordered 0 1 UUID=ab23e1d0-73a8-4707-bd7b-9c2d5063aaf9 /home ext4 rw,relatime,data=ordered 0 2
[/simterm]
Меняем рабочее окружение:
[simterm]
[root@archiso ~]# arch-chroot /mnt
[/simterm]
Редактируем /etc/mkinitcpio.conf , и в HOOKS добавляем lvm2 – перед filesystem:
[simterm]
[root@archiso /]# cat /etc/mkinitcpio.conf | grep lvm2 ## No raid, lvm2, or encrypted root is needed. ## This setup loads an lvm2 volume group on a usb device. # HOOKS="base udev block lvm2 filesystems" HOOKS="base udev autodetect modconf block lvm2 filesystems keyboard fsck"
[/simterm]
Создаём init-образ:
[simterm]
[root@archiso /]# mkinitcpio -p linux ==> Building image from preset: /etc/mkinitcpio.d/linux.preset: 'default' -> -k /boot/vmlinuz-linux -c /etc/mkinitcpio.conf -g /boot/initramfs-linux.img ==> Starting build: 4.9.11-1-ARCH -> Running build hook: [base] ...
[/simterm]
Устанавливаем загрузчик:
[simterm]
[root@archiso /]# pacman -S grub-bios
[/simterm]
Ещё раз проверяем разделы:
[simterm]
[root@archiso /]# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT loop0 7:0 0 365.4M 1 loop sda 8:0 1 14.6G 0 disk |-sda1 8:1 1 476M 0 part `-sda2 8:2 1 64M 0 part sdb 8:16 0 596.2G 0 disk |-sdb1 8:17 0 2G 0 part |-sdb2 8:18 0 16G 0 part |-sdb3 8:19 0 500G 0 part | |-kubuntu_vg-root 254:0 0 30G 0 lvm / | `-kubuntu_vg-home 254:1 0 470G 0 lvm /home `-sdb4 8:20 0 78.2G 0 part sr0 11:0 1 1024M 0 rom
[/simterm]
sdb — диск ноутбука.
Устанавливаем на него загрузчик:

Всё на месте. Теперь можно продолжать>>> установку Xorg и всего прочего.
P.S. Совсем забыл, что /dev/sdb1 — это был /boot, а /dev/sdb2 — swap. Надо обновить grub и /etc/fstab.
