Hi there and welcome
Can you tell me please exactly what steps you took to make the partition?
Then I can tell me we can undo this.
Please let me know
ok, you have lost the data sorry, it completely wiped it when you did this. Its what happens when you do partitioning.
Your best to use Gnome which is free to set the partition the way you wish and you can obtain it via my link below
But always, when making or creating partitions, make sure you backup your data first please.
If you have any problems, or would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
