I'm trying to run Oracle Virtual Box on my work laptop. I'm getting an error saying that it can't run because I'm running Hyper-v. I'm trying to follow the instructions at Scott Hanselman's Blog, which have worked for me in the past on my personal laptop with a similar issue.
I run:
bcdedit /copy {current} /d "No Hyper V"
The copy command specified is not valid.
Run "bcdedit /?" for command line assistance.
The parameter is incorrect.
I run
bcdedit /copy {current} /d /?
This command creates a copy of the specified boot entry.
bcdedit [/store <filename>] /copy {<id>} /d <description>
<filename> Specifies the store to be used. If this option is not
specified, the system store is used. For more information,
run "bcdedit /? store".
<id> Specifies the identifier of the entry to be copied.
For more information about identifiers, run
"bcdedit /? ID".
<description> Specifies the description to be applied to the new entry.
Example:
The following command creates a copy of the specified operating system boot
entry:
bcdedit /copy {cbd971bf-b7b8-4885-951a-fa03044f5d71} /d "Copy of entry"
and
bcdedit /? ID
IDENTIFIERS
Many of the Bcdedit commands require identifiers. An identifier
uniquely identifies entries contained in the store. An identifier takes the
form of a globally unique identifier, or GUID. A GUID has the following format,
where each "x" represents a hexadecimal digit.
{xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}
For example:
{d2b69192-8f14-11da-a31f-ea816ab185e9}
The position of the dashes (-) and the braces at the beginning and end of the
GUID are required.
Several entries can be identified by well-known identifiers. If an entry has a
well-known identifier, BCDedit displays it in output unless the /v command-line
switch is used. For more information, run "bcdedit /? /v".
The well-known identifiers are as follows:
{bootmgr} Specifies the Windows boot manager entry.
{fwbootmgr} Specifies the firmware boot manager entry,
specifically on systems that implement the
Extensible Firmware Interface (EFI) specification.
{memdiag} Specifies the memory diagnostic application entry.
{ntldr} Specifies a OS loader (Ntldr) that can be used
to start operating systems earlier than Windows
Vista.
{current} Specifies a virtual identifier that corresponds to
the operating system boot entry for the operating
system that is currently running.
but it looks like there's nothing wrong with my syntax, does anyone know what I'm doing wrong?
Step 1: Type “cmd” in search box. Right click the “Command Prompt” and select “Run as administrator”. Step 2: In the Command Prompt, type in: bcdedit /set {bootmgr} displaybootmenu yes and bcdedit /set {bootmgr} timeout 30. Please press “Enter” after you type each command.
BCDEdit is the primary tool for editing the boot configuration of Windows Vista and later versions of Windows. It is included with the Windows Vista distribution in the %WINDIR%\System32 folder. BCDEdit is limited to the standard data types and is designed primarily to perform single common changes to BCD.
I had exactly the same problem. I found the solution on this documentation of bcdedit from microsoft. This is just a problem when you are using powershell instead cmd.
You just have to set the identifier of the boot entry into double quotes:
bcdedit /copy "{current}" /d "No Hyper-V"
Powershell seems to have been the problem. In my powershell prompt I typed cmd and then ran bcdedit /copy {current} /d "No Hyper V"
with no errors.
