How to replace disk in VirtualBox?

Question

linux

Trying to solve the problem of increasing the size of my vmdk disk, I ran into the following problem:
Since it is impossible to resize vmdk, I convert the disk to vdi, and then I do the resize.

VBoxManage clonehd "hdd.vmdk" --format vdi "hdd.vdi"
VBoxManage modifyhd "hdd.vdi" --resize 100000

Next, I go to the settings of the virtual machine -> storage -> remove the old vmdk disk and add a new vdi.
I start the virtual machine and see: "Fatal: no bootable medium found! System Halted".
I tried to change vmdk to vdi even without resizing - the same result.
What am I doing wrong? Do you need to change the disks of the virtual machine in some other way?

Answer 1

There is a virtual media manager.
Before replacing the media, it must be "released" either in the virtual machine settings or by the manager indicated above.
