Installing GRUB on an nvme drive

I used a cloning app in windows to copy my partitions to the nvme but now I need to install a new bootloader as I am combining two drives into the one nvme.



Partition Layout:



Disk /dev/nvme0n1: 1024GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:

Number Start End Size File system Name Flags
1 1049kB 525MB 524MB ntfs Windows 10 - Reserved 1 msftdata
2 525MB 480GB 479GB ntfs Windows 10 msftdata
3 480GB 480GB 500MB ntfs Windows 10 - Reserved 2 msftdata
4 480GB 481GB 537MB fat32 EFI boot, esp
5 481GB 891GB 410GB ext4 Linux


So the old drive 1:

1: Win10 boot, 2: Win10 itself, 3: Win10 reserved. I would F8 at BIOS and boot this drive first to get into Windows.



The old drive 2:

4: EFI partition, 5: Linux root. This was set as my first drive to boot by default.



the EFI partition looks like this:



/boot/efi/:
EFI

/boot/efi/EFI:
BOOT ubuntu

/boot/efi/EFI/BOOT:
BOOTX64.EFI fbx64.efi mmx64.efi

/boot/efi/EFI/ubuntu:
BOOTX64.CSV fw fwupx64.efi grub.cfg grubx64.efi mmx64.efi shimx64.efi

/boot/efi/EFI/ubuntu/fw:


It's weird that the EFI partition has a folder named EFI as this is mounted at /boot/efi resulting in /boot/efi/EFI. If I need to combine boot to the EFI partition so the whole thing is mounted to /boot that is easy enough.



How do I set up a grub config to boot the system now?
