What sda numbur does my pc have

I have a Lenovo 300e and right now I am in BusyBox, but I don't know what sda number I have, maybe somebody could help me

1. Execute the command sudo lsblk should show you all the blocks.
   • lsblk - list block devices - from lsblk man page.
2. Another options is to execute the command sudo fdisk -l to show a list of the partitions.
   • fdisk - manipulate disk partition table - from fdisk man page.
   • -l, --list List the partition tables for the specified devices and then exit. If no devices are given, those mentioned in /proc/parti‐ tions (if that file exists) are used - from fdisk man page.
3. You can watch this thread for more ways and examples examples
   • you can run all the commands with grep command to easier find your sda partition.
   • for example sudo lsblk | grep -i sda.
   • 

Please try the command:

df -H

Here is an example from my machine:

Filesystem      Size  Used Avail Use% Mounted on
tmpfs           802M  2.1M  800M   1% /run
/dev/sda1        25G   17G  7.1G  70% /
tmpfs           4.1G   23M  4.0G   1% /dev/shm
tmpfs           5.3M  4.1k  5.3M   1% /run/lock
tmpfs           4.2M     0  4.2M   0% /sys/fs/cgroup
/dev/sda6       952G  480G  425G  54% /home
tmpfs           802M  562k  801M   1% /run/user/1000

As you can see, my root partition / is at sda1 and I have a seperate /home partition at sda6. You likely have no seperate /home partition.
