Windows BCDEdit错误，参数不正确

我正在尝试将SSD添加到启动菜单。我按照医生的指示做了。但我总是犯同样的错误

此命令显示错误：

bcdedit /copy {current} /d "mySSD"

然后我运行

bcdedit/v

查看

标识符的

GUID。此命令也给了我相同的错误：

bcdedit /copy {c562ef5b-d0f6-11e8-bfb5-e86a64139893} /d "mySSD"

错误：

The copy command specified is not valid.
Run "bcdedit /?" for command line assistance.
The parameter is incorrect.

我该怎么办

这是

bcdedit/v

问题是那些命令只在命令提示符下工作，我在PowerShell中运行它们

我在提升的powershell中运行了

cmd

，然后它工作了
