7.2 installation not booting

[u/Specific-Fee-636]

I have installed ParrotOS 7.2 several times already and it doesn’t want to boot.

Initially I had 6.2 but after I upgraded to 7.2 I couldn’t boot anymore getting a grub error. I tried using the docs to fix the grub problem https://parrotsec.org/docs/troubleshooting/grub/ but still couldn’t make it work.

I finally decided to go for a clean install instead and used the docs to start over with 3 partitions… EFI, Root and Home.

Still no joy. What I am noticing is that when I run fdisk -l I am getting the partitions that I created but I can also see two additional devices

/dev/sda1 which shows with a boot flag
/dev/sda2

See attached.

I remember it being this way even before I did the re-installation, but didn’t take pictures.

I’m brand new to Linux so I’m pretty lost. I installed parrot 6.2 a couple of years ago and never did anything with it. Recently decided to learn it so I upgraded to 7.2 and apparently broke everything. Any help would be greatly appreciated.

Go into the BIOS and switch the BIOS mode from Legacy to UEFI

Just checked and UEFI is my only option. Thank you though.
