I've followed the Beginners Guide to installing Arch Linux on my laptop. When I boot, I get the EFI boot menu, but when I select Arch Linux I get this error:
Kernal panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) CPU: 0 PID: 1 Comm: swapper/0 Not tainted 4.5.4-1-ARCH #1 ... And then the system locks up until I hard reset.
I think I must have configured the boot loader incorrectly.
My harddrive is configured with GPT partition table and partitioned as:
/dev/sda1 /boot 512MiB /dev/sda2 / 20GiB /dev/sda3 (swap) 4GiB /dev/sda4 /home 199.1GiB (remaining space) I have run bootctl install, and then created these two files:
/boot/loader/loader.conf
default arch timeout 4 editor 0 /boot/loader/entries/arch.conf
title Arch Linux efi /vmlinuz-linux initrd /initramfs-linux.img options root=/dev/sda2 rw I have checked that the /vmlinuz-linux and /initramfs-linux.img files both exist:
# ls /boot EFI initramfs-linux-fallback.img initramfs-linux.img loader vmlinuz-linux Where am I going wrong?
Edit: Thought my fstab might be useful, so posting that too (retyped manually so skipping the heading comments and the UUIDs, any typos are my transcribing):
/etc/fstab
# /dev/sda2 UUID={long uuid} / ext4 rw,relatime,data=ordered 0 1 # /dev/sda1 UUID={long uuid} /boot vfat rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro 0 2 # /dev/sda4 UUID={long uuid} /home ext4 rw,relatime,data=ordered 0 2 # /dev/sda3 UUID={long uuid} none swap defaults 0 0 
root=UUID={long uuid of sda2}(or usePARTUUID)?
