Create partitions
fdisk is text based tool used to create partitions on a disk. One can also use gparted which is gui base partitioning tool.
This tutorial assumes you are using a new SD card with no partition on it. Unmount your disk and start fdisk with your device name. In my case my SD card is at /dev/sdc. If you type p, you will see your current partition table.
fdisk - check partition |
- Make a new partition by typing 'n'. Make it primary by selecting 'p', use default partition number and first sector . Set aside 1G for this partition by typing +1G.
fdisk - new partition |
- Make this partition bootable. Set bootable flag by typing 'a'. Now if you print out the partition table, you should see your new partition with a * under Boot.
fdisk - Bootable flag setting |
- Make the root partition by typing 'n'. Select primary partition, leave the first and last sector default.
fdisk - new partition |
- If you check your partition table now, you should see the 2 partitions you just created. After verification type 'w' to write to disk and exit.
fdisk - print partition table |
Format partitions
Always format the bootable partition using fat. And 2nd partition can be ext2/ext4.
- mkfs.vfat -F 32 -n boot /dev/sdc1 - this will format the first partitions using FAT.
- mkfs.ext4 -L root /dev/sdc2 - this will format 2nd partitions using ext4.
Mount the partitions and copy the needed files.
