- Apparently there's a bug introduced by some OS upgrade. The grub menu is completely skipped under Fedora 32. No grub menu at all even though Windows 10 is detected there's the default 5-second time out for gurb menu display.
_________________________________________________
Unlike other distros like Ubuntu, major Fedora upgrades overwrite existing grub file. Next time you boot your computer, all other operating systems are gone and you boot straight into Fedora. The solution is one line:
grub2-mkconfig -o /boot/grub2/grub.cfg

Best video on the subject, no fluff, no unnecessary manual edits, anyway...perfect.
Thank you, this is very useful for my fedora references...
I just switched from Arch Linux back to Fedora (38) today. Everything works. My boot menu has Ubuntu, Windows and Fedora. No problem at all.
Perfect, thank you, it's still work under Fedora 35 (dual boot Fedora - Calculate Linux)
Fedora 36 too
Worked for me. Fedora 34. Thank's.
thank you very much man
Thank you!
perfect, work for me.
GREAT !!! Thanks !!
Thanks!!
you are the best
I've installed Android x86 as rpm and cannot add it to boot with fedora, in other linux distros i just changed custom40 file and updated grub, but i don't understand how i can do that with fedora's bootloader
I downloaded Windows (First) and Fedora (second) some time ago. Today I installed Windows 11, so windows took over my grub loader. And I cannot boot to Fedora anymore. Pressing "F12" only shows Windows and nothing else.
How can I boot in Fedora now? I do not want to re format.
You should not install Windows after Linux. I suggest that you reinstall Fedora.
Hey, ive maybe got a rare problem but when doing that, only "UEFI Firmare" shows up
Hello, I have the same problem with fedora 34, I installed with Windows and now don't work Windows, the boot menu is not show
Hey I have the same exact problem, did you solve it? What did you do?
@@zisistsatsos2509 Hola. No recuerdo exactamente como hice, creo que instale de nuevo el sistema. Volví a crear el usb boot en Euefi y me funcionó.
What to do when is the other way???. Booting straight to windows 11 and no GRUB showing
Set in your bios the windows drive as the first in boot order. If windows and linux are installed on the same physical hard drive, then you are out of luck.
sorry.. this didn't work for me
Hi, I have noticed this bug. This is quite recent, after I don't know which Fedora 32 upgrade. os-prober did find Windows 10 and Windows 10 does show up under grub.cfg. The grub file under /etc shows 5 seconds time out for grub menu. However, at boot nothing shows--grub menu is skipped completely. Fedora 33 will get released soon and I hope they will fix this bug.
Hey, today my grub menu is back with Windows 10 after sudo dnf ugprade. Fedora is a test ground for RedHat so sometimes quirky things happen.
@@turingcs2001 ugprade, he says
dont work, sorry
i have windows 11 installed on nvme, opensuse 15.4 and fedora 36 installed on the same ssd (different from windows 11). right now, on boot menu there's only fedora and windows, i only can boot to opensuse if i enter to boot menu and select opensuse partition. "this grub2-mkconfig -o /boot/grub2/grub.cfg" command seems not working for me.
when i do "sudo os-probe":
/dev/nvme0n1p1@/efi/Microsoft/Boot/bootmgfw.efi:Windows Boot Manager:Windows:efi
/dev/sda2:openSUSE Leap 15.4:openSUSE:linux

dmesg(1) may have more information after failed mount system call.
any help please?
Nether option worked
Hi thanks for your video, I get windows in the grub menu but it won't boot, it just restarts and goes back to grub menu
I checked windows system info and it says it's EFI so I don't know why this is happening, any sugestions please
os-prober reveals /dev/nvme1n1p1:Windows 10:Windows:chain
Did you check your boot order? Which hard drive is the first on your list? Boot order is in bios.
Does your Fedora boot? Sorry I have not used Fedora-been using Ubuntu and Arch.
When I run the command it detects that I have both Win 11 and Nobara but when I reboot it stays the same 🥲
