Fix: Grub Refuses Dualboot

Just yesterday during testing for a new video I noticed GRUB didn't allow os-prober to run and detect another operating system. Here is how I fixed it.

Yes, making GRUB disabling OS Prober by default is a brilliant idea. I bet everyone will benefit from it.

YES PLEASE, I am waiting for the complete tutorial on Dual Booting :)

Sooner or later I will get into this problem.
Nice to have a solution at hand.

I had very important files in my Windows disk so when I finished the Arch installation and didn’t find Windows 10 on the grub menu I started to hyperventilate 😂. Thanks alot for this, you are a lifesaver! Continue creating the good content!

Thank you very much Ermanno, now we have an answer to something that is bound to hit us all pretty soon.

Thank you for taking time for the community. Great video and great job. Thx again!!

Good video and info, Ermanno. I saw that same output yesterday when I was doing another Arch install to a vm. I thought “hey, I’ve never seen that Grub output line before.” Doesn’t bother me because I don’t use Grub to multiboot (I use a dedicated boot manager from Terabyte Unlimited), but your information is both interesting and helpful nonetheless.

Edit: btw I’d like to add that IMHO it’s better that os-prober is disabled by default. In many instances it’s better that you don’t want your new install to see other physical disks in the system.

Looking forward to your updated dual boot video. Thanks for the heads up about this problem.

Good vid.

I have had this issue 2 weeks ago, and just removed Arch... it works with Ubuntu... i couldnt figure out if I ruined the boot record. Great video! :)

[technomatic]

Sir, you're reading my mind! I had this problem last night and was thinking of fixing GRUB today. This will help me so much! Thank you!

Currently, I'm in an online class.. I'll probably fix my dual boot tonight! Really appreciate you sir!

Wow been using linux since around '99. Never had this error before ever! watched this video last night, Installed fedora alongside Arch and what do I see? This error! Thanks for the video it came in handy.

Hey, actually I had a different problem where Windows partitions aren't detected. Then I had to install *ntfs-3g* driver. This is completely different!

Thanks for updating us. I'm aware of your health issues. Just fully recover and then, get back to the amazing work :)

These little tidbits is the best, kudos for this.

THANK YOU i was stuck on arch linux the whole day and figuring out why i cant dual boot. Glad I found this vid

I noticed it some installations ago, great to have a video in case someone needs it.

[dmiracle]

Thanks for the video! This could explain a problem with dual booting Manjaro a friend had.

[josueliconamarmol]

I had the same problem yesterday with Windows 10, thank you so much. Cheers from Colombia!

Hi Ermanno, it might be worth pinning a comment to some of your older dual boot tutorials. Just concerned someone watching them might run into issues and not know what to do.

Intereseting, it tells me that it added it, but when I reboot I still don't see windows on grub
