I want to know which partition OS installed on my server.
Below is the fdisk and df command outputs from my server.
[root@ ~]# fdisk -l
Disk /dev/sda: 2000.3 GB, 2000398934016 bytes

/dev/sda3 1059 7457 51399967+ 83 Linux[root@ ~]# df -h

/dev/sda1 99M 12M 82M 13% /boot
tmpfs 7.9G 0 7.9G 0% /dev/shm
I noticed that sda1 has an asterisk on the Boot field. Does it signify that the OS is installed in that partition?
I also came upon this article, but I just want to confirm if the OS is installed on sda1.
Is there any linux command to run or files to open to see which partition the OS is installed on?

Well technically speaking, in your case, it’s installed on two partitions – sda1 and sda3. sda1 is mounted as /boot. This is where the kernel is held. sda3 is the root partition, where the rest of the OS is installed.
