Thanks Brian... of course Linux shows all the partitions.
If I use df -h on Ubuntu it shows the following 3 partitions which I assume are specifically Ubuntu partitions... correct if I am wrong.
/dev/sda5 /swap
/dev/sda8 /boot
/dev/sda9 /
Almost certainly yes.
However, if you use the "lsblk -fs" instead it will also tell you which type of filing system is on the partitions. The letters "/dev/SDx" tell you which physical or OS device it is referring to.
This is a comparison of the commands on my system here:
The entries show "sda1" is vfat because it is the UEFI boot partition,
"sda2" is formatted to Linux ext4 filing system
"sdb1" is a second drive, formatted to ntfs (it actually has Linux on it)
"sdc1" is a third drive holding legacy Windows although I never use it.
"sr0" is a Blu-Ray optical drive.
