			== Mounting disk image partitions ==
			To mount a specific partition inside a disk image, use the {{code\|fdisk}} utility to see where the partition boundaries are.

			{{highlight\|lang=terminal\|code=
			# fdisk -l out.bin
			Disk out.bin: 58.6 MiB, 61440000 bytes, 120000 sectors
			Units: sectors of 1 * 512 = 512 bytes
			Sector size (logical/physical): 512 bytes / 512 bytes
			I/O size (minimum/optimal): 512 bytes / 512 bytes
			Disklabel type: dos
			Disk identifier: 0x000981cb

			Device Boot Start End Sectors Size Id Type
			out.bin1 8192 122879 114688 56M c W95 FAT32 (LBA)
			out.bin2 122880 5785599 5662720 2.7G 83 Linux
			}}

			The first partition starts on sector 8192. Since each sector is 512 bytes, we can mount this particular partition by passing an offset of 8192 * 512 bytes.

			{{highlight\|lang=terminal\|code=
			# mount -o loop,offset=$((8192 * 512)) out.bin /mnt/card
			}}

			Alternatively, you may want to set up a loopback device specifically for a partition using {{code\|losetup}}:

			{{highlight\|lang=terminal\|code=
			# losetup /dev/loop0 disk.img -o $((10860003 * 512))
			# file -s /dev/loop0
			/dev/loop0: Linux rev 1.0 ext3 filesystem data
			# mount /dev/loop0 /mnt
			[...]
			# umount /mnt
			# losetup -d /dev/loop0
			}}
