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.      {default}               Specifies a virtual identifier that corresponds to                             the boot manager default application entry.      {ramdiskoptions}        Contains the additional options required by the                             boot manager for RAM disk devices.      {dbgsettings}           Contains the global debugger settings that can be                             inherited by any boot application entry.      {emssettings}           Contains the global Emergency Management Services                             settings that can be inherited by any boot                             application entry.      {badmemory}             Contains the global RAM defect list that can be                             inherited by any boot application entry.      {globalsettings}        Contains the collection of global settings that                             should be inherited by all boot application                             entries.      {bootloadersettings}    Contains the collection of global settings that                             should be inherited by all Windows boot loader                             application entries.      {resumeloadersettings}  Contains the collection of global settings that                             should be inherited by all Windows resume from                             hibernation application entries.      {hypervisorsettings}    Contains the hypervisor settings that can                             be inherited by any OS loader entry.
