I can't start a Virtual Machine from a VDI file obtained by VBoxManage convertdd
I have followed instructions showed by this post and in particular I started with the following dd command:
sudo dd if=/dev/sde of=/path/to/file/img/my-bootable-lubuntu.img
The source for the dd command is a SD card (/dev/sde) with lubuntu 22.04 correctly installed and bootable on its original hardware (an embedded system). In the SD card are present 2 partitions: the boot partition and the root partition with all the lubuntu distribution.
After dd I have executed commands:
> cd /path/to/file/img
> VBoxManage convertdd my-bootable-lubuntu.img my-bootable-lubuntu.vdi --format VDI
By the previous command I get the file my-bootable-lubuntu.vdi.
I would like to create a VirtualBox virtual machine by this .vdi file, so I have added it as an Hard-Disk for the new virtual machine as showed in the following picture:
When I try to start the virtual machine I immediately obtain the error:
FATAL: Could not read from the boot medium! System halted
What could be the problem?
In reality everything works. My mistake was booting the Virtual Machine by the Start button (see image below):
before pressing the OK button present in the tab used to add the VDI disk to the SATA controller (see image below):
Perhaps I have repeated this error more than one time. By pressing correctly the button OK all starts working.
So the procedure showed here works perfectly.
