Harddisk partion
I only have one partition in my sda harddisk. I don't have an sdb partition. Changing the OS will delete all of my data.
If I create a new partition and copy my data there, will this work?
Yes!
however, put this in mind
- make sure the partition is in the end block of your drive, otherwise you will not be able to resize it back to its original size
- make sure to not format or delete the partition because there is no way to restore your data
- some Linux distros will force you to use the whole disk e.g fedora Linux, so be aware
