I’m trying to mount a raw Armbian disk image without writing it to sd card or an usb stick with following command and getting error:

```auto
$ sudo mount -o loop Armbian_5.35_Orangepizero_Ubuntu_xenial_default_3.4.113.img /mnt/tmp
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try
       dmesg | tail or so. 

```

How can I mount the partition in the image? `file` output shows following information about image:

```auto
$ file Armbian_5.35_Orangepizero_Ubuntu_xenial_default_3.4.113.img
Armbian_5.35_Orangepizero_Ubuntu_xenial_default_3.4.113.img: DOS/MBR boot sector; 
  partition 1 : ID=0x83, start-CHS (0x40,0,1), end-CHS (0x3ff,3,32), 
  startsector 8192, 2834432 sectors

```

It is quite easy but you need to skip some bytes to position on the first partition.

As you can see on the output of the `file` command, start sector of given image is **8192**

Because of the each sector in a disk is **512** bytes, you need to skip 512x8192 = **4194304** bytes. So, exact command must be like that:

```auto
$ sudo mount -o loop,ro,offset=4194304 \
        Armbian_5.35_Orangepizero_Ubuntu_xenial_default_3.4.113.img /mnt/tmp

```
