I am new to ubuntu when I install it on virtualbox I assign it 8gb normal size of disk space, but now it shows me popup for low disk space. I don't know how can I increase disk space to get rid of this warning.
I tried using following command: VBoxManage modifyhd YOUR_HARD_DISK.vdi --resize SIZE_IN_MB but received an error
'VBoxManage' is not recognized as an internal or external command, operable program or batch file.
any suggestion would be much appreciated.
Looks like your host OS is Windows. Since VBox program directory is not in PATH variable by default, you need to specify a full path manually. Or change current dir to VBox program dir. Try to run
cd C:\Program Files\Oracle\VirtualBox
first to change current directory in cmd, and then run your command.
