Problem after removing partition on SD card

Hey there, this might sound crazy. But as I was partitioning my micro sd card. I decided to remove the partition. And when I did that. It is now undetectable by my laptop or any laptop for thaf matter but I formatted the card on my phone, and it works for my phone. But not my laptop. I am trying to partition the sd card because I am using it to store files from my internal rooted phones memory to the sd card internals. I really need help badly! Is there any way you can help?
