Dual boot Leap 42.2 plus Windows 10 won't boot into windows anymore

Hi!

I’m fairly new to this community. I bought a Lenovo X1 with pre-installed Windows 10. Since so far I’ve been happily using OpenSuse / Leap but find it convenient to have access to windows once in a while as well I wanted to create a dual boot of Windows 10 and Leap 42.2.

What I did so far:

  • under windows resized the C from 500GB to 250 GB
  • installed Leap 42.2 via DVD on the then remaining 250GB

Now, if I restart I’m being lead through the whole Leap installation process again and again without ever being able to use or configure my Leap.
Searching for an answer I found that UEFI/Secure boot may be part of the problem and that I need to start Windows 10 and there as an admin do

bcdedit /set {bootmgr} path \EFI\opensuse\shim.efi …if secure boot is enabled
bcdedit /set {bootmgr} path \EFI\opensuse\grubx64.efi …if secure boot is disabled

Problem is: for some reason, I cannot boot windows anymore. In BIOS, I put the Windows Boot Manager on top of the booting order. But that does not help.
Any ideas?

Thanks in advance!

ps. I’m sure much more information from my side is needed. If so, please let me know which.

Hi
Boot into openSUSE and open a terminal and switch to root user and
run the following commands;


os-prober
efibootmgr -v

If os-prober returns it see’s windows 10 and you see a Windows Boot
Manager entry from the output of efibootmgr then go into YaST
bootloader and ensure on the last tab the os-prober entry is checked
and save.

This should add an entry into the grub boot menu so you can boot into
windows 10.

Hi!

thanks for your quick reply!

The problem is that I cannot boot Suse either. I am always being directed to the Leap installation procedure, although I already installed it.

Hi
Ok, so can you select the rescue option to boot to, username root and no password. Here can you run the efibootmgr command.
