I need to see the BCDedit for a Windows10/Ubuntu install both by Wubi and by separate partition

I seem to have windows passing by on GRUB/Ubuntu. There's no Ubuntu folder under Windows. I can boot from firmware to Grub, then choose either OS. I removed Wubi/Ubuntu and reinstalled directly to the same partitions.

The windows Boot Manager did not create an entry for Ubuntu, so I need to create the entry. Wubi puts wubildr.mbr on my system... but this is the wrong thing for EFI installs. I need the shimx64.efi so the created Windows boot in EFI might work.

I will make a copy of my boot with bcdedit, and point the entry to Ubuntu.

If this is incorrect, please tell me what to do next?

If you want to add an UEFI entry for Ubuntu with bcdedit, you can use the following commands as administrator:

List all BCD entries for UEFI:

bcdedit /enum firmware 

Copy UEFI entry of "Windows Boot Manager" to create a new entry for Ubuntu:

bcdedit /copy {bootmgr} /d "Ubuntu Secure Boot" 

Set file path for the new Ubuntu entry. Replace {guid} with the returned GUID of the previous command.

bcdedit /set {guid} path \EFI\ubuntu\shimx64.efi 

Set optionally Ubuntu as first entry in the boot sequence. Replace {guid} with the returned GUID of the copy command.

bcdedit /set {fwbootmgr} displayorder {guid} /addfirst 

Alternatively, you can use a script which does the job for you:

@ECHO OFF rem add Ubuntu EFI entry bcdedit /enum firmware for /f "tokens=2 delims={}" %%a in ('bcdedit /copy {bootmgr} /d "Ubuntu Secure Boot"') do set guid={%%a} bcdedit /set %guid% path \EFI\ubuntu\shimx64.efi bcdedit /set {fwbootmgr} displayorder %guid% /addfirst bcdedit /enum firmware 

The easiest way for your intention should be EasyUEFI. EasyUEFI can create an entry for Ubuntu. \EFI\ubuntu\shimx64.efi is the right file path for that entry. If necessary, you can also change the boot order.

adding to @hakuna_matata 's answer you should execute :

for other os default

bcdedit /displayorder {guid_of_os} /addfirst 

for windows as default

bcdedit /displayorder {guid_of_os} /addlast 

syntax

bcdedit /displayorder <id> [...] [ /addfirst | /addlast | /remove ] 

you will get Ubuntu during boot on options
