韶关到呼和浩特火车:让 virtualbox支持从硬盘、U盘启动

让 virtualbox支持从硬盘、U盘启动

#进入命令行
CODE:

cmd
cd C:\Program Files\Oracle\xVM VirtualBox

#获取磁盘信息(这个最关键)
CODE:

wmic /output:d:\diskdrive.html diskdrive list /format:htable

#打开d:\diskdrive.html ，查看DeviceID栏，获取到你的U盘DeviceID，如\\.\PHYSICALDRIVE1

#获取磁盘分区信息（确认是哪个U盘）
CODE:

VBoxManage internalcommands listpartitions -rawdisk \\.\PHYSICALDRIVE1

下面是我的U盘信息，8G的，显示7655MB
QUOTE:

Number Type   StartCHS       EndCHS      Size (MiB) Start (Sect)
1       0x0b 0   /0 /45 975 /254/63          7655           44

#为U盘创建启动文件
CODE:

VBoxManage internalcommands createrawvmdk -filename d:\UsbDisk.vmdk -rawdisk \\.\PHYSICALDRIVE1

#打开virtualbox-->设置-->硬盘-->添加连接（Ins）会找到刚才新建的UsbDisk.vmdk（如果没有自动找到，手工添加就可以了）
#常规-->高级-->Boot Order-->硬盘，启动你的虚拟机，成功了！
