Missing ubuntu entry in Windows 10 Boot Manager #15

Open mcbyte-it opened 8 years ago

mcbyte-it commented 8 years ago

I just installed Ubuntu Mate on my Windows 10 Pro 14393 (Anniversary Edition). Wubi install failed first time after downloading the iso (couldn't extract). I then repeated another time by mounting iso in explorer and installation went fine, it rebooted and installed ubuntu. But now I don't see Ubuntu in the Windows boot manager, laptop boot directly into Windows, bcdedit /enum doesn't show anything for ubuntu, just Windows boot manager and Windows 10.

I am using an UEFI system, without secure boot, and GPT partition table.

can I add the entry with bcdedit manually? what command should I run?

mcbyte-it commented 8 years ago

Checking bcdedit with detailed enum, I see it is there, but now showing:

C:\>bcdedit /enum firmware

I found out that it doesn't show because the entry is not in the {bootmgr} display order, I had to execute manually the command:

bcdedit /displayorder {id} /addlast

Now it shows upon boot, but it still doesn't work:

File: \EFI\ubuntu\wubildr\shimx64.efi
Status: 0xc000007b
Info: The application or operating system couldn't be loaded because required file is missing or contains errors.

Guess this is my final update:

The entry in {fwbootmgr} works if I go to the bios settings, there I see Ubuntu, and when I select it to override default boot Ubuntu works perfectly.

The problem is that my bios doesn't show boot options, so each time I want Ubuntu I have to start with bios and override, or set it as default.

Is there a way to enable EFI boot with the Windows Boot Manager?

The problem is that my bios doesn't show boot options, so each time I want Ubuntu I have to start with bios and override, or set it as default.

Maybe, it is helpful to manage EFI boot options without starting firmware/BIOS. There are Windows programs like EasyUEFI which can do it.

It is also possible to use bcdedit to manage EFI boot options. e.g.

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

to set the entry with {id} to the top of the firmware/BIOS boot menu.

EFI boot is enabled because your Windows uses the Windows Boot Manager for EFI systems but there are known issues with non-Microsoft programs if you want to start them from BCD menu. Wubi has similar problems as described here for EasyBCD. That is the reason why Wubi uses the firmware/BIOS menu if your Windows is installed in EFI mode.

Thanks @hakuna-m for the workaround to this problem. I'm still unable to make windows boot manager show the ubuntu entry, but now every time I want to switch to ubuntu I only have to use EasyUEFI then select the ubuntu entry and clic one time boot. Then I reboot the pc and voila!

nhymxu commented 7 years ago

EFI system need to choose when bios logo load ( press some function button to display boot menu - using when choose usb device to boot ), then wubi display here.

Because EFI system load menu from EFI system partition - not windows boot menu

enochmh commented 7 years ago

@nhymxu unfortunately that does not work for me. I'm using a toshiba radius 12. When I press f12 and then on the boot menu nothing is there. there is no entry for wubi. only the usb boot option and the ssd.

hakuna-m commented 7 years ago

@enochmh Interesting. Regarding Gentoo Wiki your Toshiba Radius 12 has only poor UEFI support:

Long version: The system supports it, but poorly.

But if Windows 10 is preinstalled in UEFI mode, you need UEFI support to run Windows 10. So it is not really a good option to switch it off for a dual-boot with Ubuntu. So it seems Wubiuefi with EasyUEFI is also a solution for a firmware/BIOS with poor UEFI support.

Here is just my comment. My computer is Mini PC Intel® NUC Kit NUC6i7KYK. At first, I installed win10. Then I installed Ubuntu 16 with wubiuefi. Due to EFI, there's no windows manager. It just goes through into win10. I checked it with EasyUFI under Win10. I found Ubuntu was there with "hidden" status. I moved it to the top and switched shimx64.efi to grubx64.efi (because I disabled the secure boot). Then I restarted the computer. Everything is ok~

hakuna-m commented 7 years ago

@miluoZ Thanks for your comment.

and switched shimx64.efi to grubx64.efi (because I disabled the secure boot)

That should be not necessary. shimx64.efi also launches grubx64.efi if Secure Boot is disabled.

Hi there,

I had similar problems with an acer: the entry was not showing it up, so I forced it with commmand "bcdedit /displayorder {id} /addlast". This way I can see the entry in the win boot loader but still it's not loading, giving oxc00007b error. Then I tried creating a new entry with easyuefi but it's not showing neither in the uefi menu nor in the win boot loader. I also tried with visual bcd editor but it's not that easy to configure. When adding entries with this sw I can see them in win boot loader though. Any suggestions ?
