Zorin OS 15.03 lite not booting after resizing root partition

[Sifat06]

I am dual booting zorin os 15.03 lite with windows 10. When I resized the root partition from a live usb with GParted, I could not boot on zorin os again. When I try to do so, I only see this screen.

When I try to boot on recovery mode, I see this.

So, I tried to repair boot with 'boot-repair'. I installed this on my zorin os live usb. When I run 'Recommanded Repair' , I get this messege, "grub-efi-amd64-signed purge cancelled. Please report this message to boot.repair@gmail.com". then I created a "BootInfo Summary" with the app,and here it is.

Can any one help me please??
(Note that Windows is installed in UEFI mode, where Zorin os is installed in Legacy Mode. My hardware and both system is in 64-bit.)

I resized the root partition from a live usb with GParted,

@337harvey Just to flag that I think the OP used his Live USB Gparted to adjust the partition, not Gparted from installed OS.

Hypothetically asking, under normal circumstances, if the OS partition is resized, Zorin will still operate normally correct? I've done this a number of times before with Windows, but I've never done it with linux. I assume it's going to be fine.

Yes, that should not be a problem. I've re-sized Zorin and other Linux partitions without difficulty, using Gparted. There's always some risk when repartitioning of course, but generally it's fine.

Looks like, I've figured out the solution myself ! What I did is just created a 2 MiB unformatted partition with BIOS_boot flag and installed grub from live USB just as instructed here. And, it fixed my problem! Btw, thanks for replying on my post !

I believe you answered part of your own question. I don't know how you did it, but to install zorin in legacy while windows is in efi is nearly impossible. Legacy uses the mbr structure which limits the number of primary partitions to four and the rest are extended partitions(again with a limit). Efi uses the gpt structure allowing for many partitions, all bootable of necessary. These structures are so different they don't work together. That may be part of your problem.

YES! I was(and still after the repair) running. And moreover, I am also able to boot windows from boot menu in both legacy and UEFI mode. Where, I can only able to boot Zorin OS from only Legacy mode. I don't know how (I was also surprised when I first discoverd this), but I can!
