Had the same problem -NO HELP ANYWHERE - these forums need to better helped!

I fixed it by mounting this Grub Rescue ISO (https://www.supergrubdisk.org/super-grub2-disk/ ) to the VM
booted off ISO
it automagically finds the "upgraded’ Parrot boot option, choose it and boot
PArrot will boot normally

open a Term and do the following

sudo grub-install /dev/sda

reboot and ALL Fixed (although I seem to have lost screen resizing on Oracle Box for now)

hi,

dont know what you guys doing but i have 5 install. of parrot (3 diff. laptops and 2vm `s) running without any problems.
we have tons of posts her in the forum cause users dont read our docs. or faq. for example:

  • they are logged in as root
  • do not flash with etcher
  • update there systems with apt upgrade
  • etc … etc

What the people here always forget is: we are a free community here. and the community thrives on the help of its members.

So please be so nice (respectfull) and save you comments like these up there!
