[SOLVED]Cant boot after fresh install

A few days ago i reinstalled Arch Linux from wiki (wish configuring users and grub was listed, i take help from web on that one) in 3. try i managed to install and boot. I was running system for 1 week or so. But today its stuck on the boot screen and when i press restart button, this is what i get:

[       3.349090]   ? asm_exc_genera;_protection+0x26/0x30
"
"
"
... continues
mount: /new_root: unknown filesystem type `ext`.
            dmesg(1) may have more information after failed mount system call.
You are now being dropped into an emergency shell .
sh: cant access tty; job control turned off
[rootfs ~]# fdisk -l
sh: fdisk: not found
[rootfs ~]# sudo fdisk -l
sh: sudo: not found
[rootfs ~]# ls
VERSION   buildconfig    dev   hooks   init_function   keymap.bin   lib   new_root   root   sbin   tmp   var
bin   config   etc   init   kernel   keymap.utf8   lib64   proc   run   sys   usr
[rootfr ~]# lsblk -l not found

What output need for solving the problem, please ask for it.

Edit: no encryption, only / partition not UEFI. Its BIOS/MBR

SOLUTION: Boot in to USB live Arch Install
mount partition of root and boot (in my case root and boot is once) to /mnt and /mnt/boot
arch-chroot /mnt
mkinitcpio -P
exit
umount -a
reboot

Re: [SOLVED]Cant boot after fresh install

Now that you have rebooted, check that your boot partition is being mounted.  If it is not, the problem will recur next time the kernel is updated.

What do you mean by "in my case root and boot is once"?

Please post the exact, full commands that you used. Do not describe the commands, just copy them here exactly as they were entered.
