As you’ll understand from my limited post history, I’m a linux noob. My colleague set up my dual boot system. Or tried.
My issue is that when I boot my computer it goes directly into linux. This is mostly fine but I would like to be able to access Windows at times.
I have found the YaST Boot Loader and under “Bootloader Options” a drop-down menu offers a “Window Boot Manager”. Before I select this and restart my computer, are there any warnings from this community that I should take into account? Can this screw up my access to return to opensuse, where all of my work is located? I’ve not used Windows in a year of having this pc.
Please let me know what information you require from my setup.
“The easiest way to configure general options of the boot loader in your openSUSE Leap system is to use the YaST module. In the YaST Control Center, select System › Boot Loader. The module shows the current boot loader configuration of your system and allows you to make changes.”
Make sure that the file /etc/default/grub contains the following definitions
(and make sure that each of those parameters is set only once in this file).
Then switch to a virtual console (Ctrl+Alt+F2) login as “root” and do
# grub2-mkconfig -o /boot/grub2/grub.cfg
# systemctl isolate reboot.target
what should reboot your machine.
If your system still boots directly into openSUSE without showing any GRUB2 menu then please load the files /etc/default/grub and /boot/grub2/grub.cfg up to https://paste.opensuse.org and post the link here.
By the way:
Are you UEFI- or CSM-booting?
Do you have secureboot enabled?
When I rebooted, I again had a black screen. Previously, this would eventually lead me directly to Opensuse. The first time returning to this black screen, I had the thought that, perhaps I am just not seeing the menu?
So I scrolled down once and hit enter. This brought me to Windows!
This is good news, however, now when I reboot (still with a black screen initially) I hear a single beep and I am directed straight to Windows. I can no longer access Opensuse, it seems.
Please, if anyone has advice for me, let me know. I have some important files on my linux partition that I stupidly did not back up before playing with this.
Fast boot is own and Windows thinks it is hibernating
The UEFI is one that insists you use Windows.
You should have a UEFI boot option. Which key to hit depends on the Hardware. Consult the Docs for the Machine/Motherboard. The options may show at the bottom of the Machines splash screen for a short time.
Run the command as „root“ in a console (Ctrl+Alt+F2) and show the complete output; i.e. include the command line you used, the output and the next (empty) prompt and enclose all in CODE tags (# button in the tool bar of the forum editor).
Sorry! Just saw your latest posts.
If you cannot boot into your installed openSUSE system boot your installation media, start the rescue system and issue then the command shown above.
