Accidentally shutdown OS while installing

I was installing manjaro with dual-booting via calamares, and tried to close my laptop lid to see if it would just keep working and stay on while the cover was closed. Instead, my surface keyboard sent the shut down signal while it was at one percent install. My computer still boots fine, but I can’t install manjaro anymore, as it encounters an error with the booting.

How can I reset the partitions so I can resume the install?

boot on USB live iso
then format only disks or partitions linux with gparted

you can launch install after
