Changing the boot sequence

To change the boot sequence follow the steps:

:

  1. Check for the boot order type (Legacy or UEFI) by using the following command :
    • WMIC Command: wmic /namespace:\\root\dcim\sysman path dcim_BootConfigSetting get ElementName/format:list .
    • PowerShell Command: gwmi -namespace root\dcim\sysman -class dcim_BootConfigSetting -Property ElementName .
  2. Check for the current boot order type (Legacy or UEFI) by using the following command :
    • WMIC Command: wmic /namespace:\\root\dcim\sysman path dcim_ElementSettingData.IsCurrent=1 get SettingData /format:list .
    • PowerShell Command: gwmi -namespace root\dcim\sysman -class dcim_elementSettingData -Filter "IsCurrent=1" -Property SettingData .
  3. Changing boot-order by using the following command :
    • WMIC Command: wmic /namespace:\\root\dcim\sysman path dcim_bootconfigsetting call ChangeBootOrder /?:full .
    • PowerShell Command: (gwmi -namespace root\dcim\sysman -class dcim_bootconfigsetting).getmethodparameters("ChangeBootOrder") .
      • NOTE: dcim_BootConfigSetting instance must represent the boot configuration that you want to change – either type 1 (Legacy) or type 2 (UEFI).
    • The arguments are:
      • Authorization Token — This is the Administrator or boot password.
      • Source — This is the boot order list taken from dcim_OrderedComponent.PartComponent property. The new boot order is determined by the order of boot devices in the source array.
  4. Changing Boot order for type 1 boot-list using PowerShell :
    1. Get Current Boot-order for type 1 boot-list by running the following command: $boLegacy = gwmi -namespace root\dcim\sysman -class dcim_orderedcomponent | where {$_.partcomponent -match 'BootListType-1'} | select -expand partcomponent.
    2. Define a PowerShell variable to specify boot-order to set $newboLegacy. Assign the new boot-order to it. For example, Current boot-order type is retained.
    3. $newboLegacy = $boLegacy
    4. Get dcim_bootconfigsetting instance corresponding to type 1 boot-list by running the following command: $bcsLegacy = Gwmi -Namespace root\dcim\sysman -ClassName dcim_bootconfigsetting | where {$_.ElementName -eq 'Next Boot Configuration Setting : Boot List Type 1'}.
    5. Invoke the method by running the following command: $ bcsLegacy.changebootorder($newboLegacy, $AuthorizationToken). $AuthorizationToken variable is used to pass the BIOS password.
  5. Changing Boot order for type 2 boot-list using PowerShell :
    1. Get Current Boot-order for type 2 boot-list by running the following command: $boUefi = gwmi -namespace root\dcim\sysman -class dcim_orderedcomponent | where {$_.partcomponent -match 'BootListType-2'} | select -expand partcomponent.
    2. Define a PowerShell variable to specify boot-order to set $newboUefi. Assign the new boot-order to it. For example, current boot-order type is retained.
    3. Get dcim_bootconfigsetting instance corresponding to type 2 boot-list by running the following command: $bcsUefi = Gwmi -Namespace root\dcim\sysman -ClassName dcim_bootconfigsetting | where {$_.ElementName -eq 'Next Boot Configuration Setting : Boot List Type 2'} .
    4. Invoke the method by running the following command: $ bcsUefi.changebootorder($newboUefi, $AuthorizationToken). $AuthorizationToken variable is used to pass the BIOS password.
