Ubuntu Version:
18.04.2 LTS
GRUB Version:
2.02
Desktop Environment (if applicable):
XFCE
Problem Description:
GRUB is not working correctly after converting native xubuntu to virtualbox image.
Basically GRUB does not works. XUbuntu does not start. It fails during startup.
I wanted to convert native OLD xubuntu machine that was used for development some years ago. After SSD died in old macbook I became paranoid and wanted to backup this stuff. Ideally I wanted to access this on my new laptop - lenovo p16 gen1 as virtual machine.
I did quick research and easiest way was to use this guide from virtualbox forums (vCenter was nice on “paper”, but practically doing this via VMware vCenter was hassle/problematic).
Problem is that on OLD PC, I have dual boot, windows 10 + Xubuntu. Boot partition is on windows ssd, xubuntu uses different ssd
I did dd whole image for linux ssd and dd windows boot partition
dd if=/dev/sdb of=/media/EXTERNAL_DRIVE/sdb.img bs=1024
dd if=/dev/sda2 of=/media/EXTERNAL_DRIVE/sda2.img bs=1024
Then converted this via VBoxManage and I have working vbox image.
Here goes lsblk -f from native xubuntu.

860 evo win10 stands for Samsung 860 evo - here I have installed windows 10.
As we see on sda2 we have /boot/efi.
sdb is samsung 850 pro. Here we have 3 partitions: swap, / and empty boot sdb3.

Only tried various options with booting in virtualbox, but result is the same.
