Два вопроса:
1. Зачем бут отдельный?
2. Кто надоумил делать его в fat32?

For example, an EFI System Partition must contain a FAT32 (mkfs.vfat) file system, and the file system containing the /boot directory must be supported by the boot loader.

Create mount points for any remaining partitions and mount them accordingly, for example:
# mkdir /mnt/boot
# mount /dev/sda2 /mnt/boot

Heinardt, а у тебя случаем не Manjaro?

Linux arch 4.12.12-1-ARCH #1 SMP PREEMPT Sun Sep 10 09:41:14 CEST 2017 x86_64 GNU/Linux

sudo nano /etc/mkinitcpio.conf

ahci sd_mod

sudo mkinitcpio -p linux

Morisson
Это через чрут, наверное, нужно будет делать,- у тебя ж система не запускается?)

Heinardt
Проблему я конечно устранил с live-usb, пересоздав раздел с новым ядром и подправив fstab

Morisson
Heinardt, testing?

# By default, pacman accepts packages signed by keys that its local keyring
# trusts (see pacman-key and its man page), as well as unsigned packages.
SigLevel    = Required DatabaseOptional
LocalFileSigLevel = Optional
#RemoteFileSigLevel = Required

# NOTE: You must run `pacman-key --init` before first using pacman; the local
# keyring can then be populated with the keys of all official Arch Linux
# packagers with `pacman-key --populate archlinux`.

#
# REPOSITORIES
#   - can be defined here or included from another file
#   - pacman will search repositories in the order defined here
#   - local/custom mirrors can be added here or in separate files
#   - repositories listed first will take precedence when packages
#     have identical names, regardless of version number
#   - URLs will have $repo replaced by the name of the current repo
#   - URLs will have $arch replaced by the name of the architecture
#
# Repository entries are of the format:
#       [repo-name]
#       Server = ServerName
#       Include = IncludePath
#
# The header [repo-name] is crucial - it must be present and
# uncommented to enable the repo.
#

# The testing repositories are disabled by default. To enable, uncomment the
# repo name header and Include lines. You can add preferred servers immediately
# after the header, and they will be used before the default mirrors.
