kernel panic-not syncing: VFS: unable to mount root fs

Hi,
I'm trying to dual boot Arch with Windows 10 on a UEFI system, but keeping getting the error in the subject line when I reboot. I'm using the windows created EFI partition residing at /dev/sda2 as my /boot, and /dev/sda6 as my root partition (/dev/sda6, as well as /dev/sda7, my eventual home partition, are formatted as ext4)
This is my loader.conf file

 timeout 3
default arch
editor	0 

This is the contents of arch.conf

 title		Arch Linux
linux		/vmlinuz-linux
intrid		/intel-ucode.img
intrid		/initramfs-linux.img
options		root=PARTUUID=70a8c5e2-c4b5-4f9c-92e3-6e768396b44b rootfstype=ext4 rw
 

This is the output of blkid (i'm not sure if this is needed)

/dev/sda3: PARTLABEL="Microsoft reserved partition" PARTUUID="4cf703a9-4bb0-4d16-9a4c-0c0af5e68818" 

This is the contents of my fstab file

 # 
# /etc/fstab: static file system information
#
# <file system>	<dir>	<type>	<options>	<dump>	<pass>
# /dev/sda6

Windows boots into a recovery mode, which I assume is from re-sizing the primary windows partition. I'm not sure what other information I need to provide, and I'm sorry if didn't give everything pertinent. To be clear, the full error when I attempt to boot into Arch is

 ---[ end Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) 

Thank you so much for the help.

Re: kernel panic-not syncing: VFS: unable to mount root fs

Hi, you have a typo in your arch.conf; you wrote intrid instead of initrd.
This made me read again each line of my entry (I had the same issue than you) and found also a typo in my initrd line that fixed my issue! So it should fix yours!
