** After applying the edits with GParted I haven't been able to boot with a graphical interface. Instead after initializing the screen turns black with a blinking cursor in the top left corner. **

I have similar issue, not identical, You may wanna try this: [Fixing the black screen after grub boot-up (screen/video settings mismatch)]

    So I recently moved around the Linux swap partition and resized the root partition of my Parrot installation on my hard disk to increase available space. After applying the edits with GParted I haven't been able to boot with a graphical interface. Instead after initializing the screen turns black with a blinking cursor in the top left corner. From what I presume, this is associated with an error in GRUB. For the past two weeks, I've looked at various options over how to deal with the problem, but have found no solution. After getting a shell with Ctrl+Alt+F1, I've ran update scripts with apt-get, grub, and initramfs. There is also a possible error having to do with the segmentation of arrays. Long story short I was also experiencing failure in one of my SATA cables connecting to my CDROM drive. After replacing it, the ata1: error: messages no longer appeared, along with the mdadm: No arrays found in config file or automatically, however after running the bootinfoscript as suggested by various sources, the issue still persists. I'm at a loss here as I've tried various ideas yet have seen no results.

    Here are some resources for the issue:

    bootinfoscript:
