Laptop: Installation OK, Bootloader shows "Kunbuntu" but then I get Windows only
Closed this issue · 6 comments
I have used on a Lenovo-Laptop Wubi for Ubuntu 22.04.2 (rev. 345).
Installation works fine (almost 2 days for Kubuntu-torrent!). After restart and "F12" during booting I could choose a boot device: I choose "Kubuntu", but I get Windows (exact the same as choosing "Windows Boot Manager")!
I appreciate any help to boot Kubuntu!
Wubi(uefi) uses Windows command bcdedit to change menu entries.
So it is necessary to analyze the view of your menu entries with bcdedit.
- Start command prompt as administrator with e.g the following method:
- Use Windows + R Keyboard Shortcut
- Type “cmd“
- Press Ctrl + Shift and hit Enter key.
-
Type `bcdedit /enum firmware
-
The output should be something like that: #15 (comment)
-
In your case, the path of the menu entry for "Kubuntu" is important.
Windows Boot Manager

It should be \EFI\ubuntu\wubildr\shimx64.efi.
Thank you a lot for your fast and detailed answer!
Following your advice I get following output:
C:\Users\Administrator>bcdedit /enum firmware

...
So there is after "path" "\EFI\ubuntu\wubildr\shimx64.efi"!
Do you have another idea what could be wrong?
Thank you in advance!

Does the boot menu show before Windows attempts to boot? Restart your computer through Windows. Hold shift before clicking restart. I'm not exactly sure where the option to boot a different system from the Windows boot menu is. But when you find it, click it. The entry might be called Kubuntu or Ubuntu.
Holding shift during clicking restart results in a screen with four options: I choose "Fortsetzen"
Test 1: doing nothing during restart: I get Windows
Test 2: "F12" during restart: "Please select boot device" - I select "Kubuntu", but I get Windows (exact the same as choosing "Windows Boot Manager")!
Any idea how I can start Kubuntu? - Thank you!
Probably, it is necessary to disable Secure Boot because of a new "security" feature of some Lenovo laptops: https://mjg59.dreamwidth.org/59931.html
Check for Secure Boot
Disable Secure Boot
Also in German available.
Thank you a lot for your fast and detailed answer!
Following your guide (1):
How can I check in Windows if Windows is installed in UEFI mode with Secure Boot ?
- Press Windows + R
- Type msinfo32
- Look for entry | BIOS Mode | UEFI |
- If BIOS mode is UEFI look also for | Secure Boot State | On |
Result: Secure Boot is enabled!
Following your guide (2):
How can I change UEFI firmware settings from Windows ?
- Find Shut down / Restart menu
- Press Shift + click on Restart
- After restart click on Troubleshoot -> Advanced options -> UEFI Firmware Settings -> Restart
Result: System Password:
System Password:
I have the administration password for windows, only :-(
Therefore, I can't proceed :-(
Conclusion: Don't see any chance to succeed and therefore I give up. Thank you for your help - and keep up your highly appreciated work!
