beaglebone fstab edit can't boot

I modified my fstab file in my BBB however I think I did a bad entry and now my BBB can’t boot anymore. How to remove the line from fstab since I can’t boot so i can’t ssh it ?!
My image is under my SDCard so I can remove it and plug it under my computer but i don’t know how to access my fstab from there…!

BBB boot fine without my SDCard but I need my SDCard data so i reaaly need to be able to boot from it

Thank you :slight_smile:
