What does sudo fdisk -l mean?
This is the output. I installed Windows7 and Ubuntu. Using fdisk, I get four partitions. What does each partition mean? Which one is Ubuntu? Which one is Windows7?
sudo fdisk -l lists all the partitions on all your storages partitioned with msdos partitioning label.
I think that,
/dev/sda1 is active primary partition.
This partition has Windows 7 boot loader.
/dev/sda2 is primary partition formatted as NTFS.
This partition has Windows 7.
/dev/sda3 is primary partition formatted as swap space.
This is a swap space used by Ubuntu.
/dev/sda4 is primary partition formatted as a linux file system(ex: ext2/ext3/ext4...).
As result,
/dev/sda1 and /dev/sda2 is used for Windows 7,
/dev/sda4 is the /(root filesystem) for Ubuntu,
/dev/sda3 is swap space for Ubuntu. Swap space is a space on a hard disk used as the virtual memory extension of a computer's real memory.
