我正在运行 debian 7 并尝试使用以下方法安装 virtualbox：
sudo apt-get install virtualbox
并获得此输出：

我想创建四个分区：
/boot 300 MB ext2 --> primary or logical?
/ 30 GB ext4 --> primary or logical?
swap 4 GB swap --> primary or logical?
/home 100 GB ext4 --> primary or logical?
FREE SPACE for a possible other OS
如果我将每个分区设为主分区，分区管理器将不允许我在空闲空间中创建另一个分区。我猜这是因为我最多可以做四个主分区。那么我应该将一个分区设为主分区（哪个？），其余分区是逻辑分区，还是全部是逻辑分区，或者...？
