I'm new to Linux.
I have an old laptop with 500 GB HDD. It used to have Windows 10 installed on C: drive. I also had other drives namely D:, E;, F:. where my important documents was stored. This was done to have no impact of OS re-installation / upgrade on my personal documents.
I've now switched to Linux (Ubuntu) & following some online guidance, I did manual partitioning of the HDD during installation. Here apart from required partitions like (/, /home, /usr etc), I have created some extra partitions (/d (100 GB), /e (100 GB), /f (100 GB), /g (114 GB)) for myself, hoping to store my personal documents in those partitions. The output of sudo fdisk -l shows:
My question is if I reformat / re-install Linux again / upgrade OS in future will the /d (sda9), /e (sda10), /f (sda11), /g (sda12) partitions survive?
