BSOD: Inaccessible boot device after updating from April 2018 to May 2019 update

Currently running a dual-boot system on a Lenovo Yoga 730 with manjaro and windows 10.
Upon restarting and allowing Windows Update to upgrade to the May 2019 update, I get a stop error with INACCESSIBLE_BOOT_DEVICE.

Initially, GRUB menu wouldn't appear, but has now appears but will not boot linux.

How do I go about fixing this?
