Did you use grub-customizer or create any custom config files?

grub customizer is a pretty common cause of grub issues.

How grub-customizer made it into the Arch Community repo is beyond me.

It is so popular, because many newcomers to the Linux world like to double-boot their Woondoze alongside before potentially making a complete switch.
In that regard grub-costumizer earns it’s right to live. Once the user experience on Linux matures to a more self-sustained skillset, it won’t be needed anymore, and parting from it, in the beginning always means some pain, but a greater learning curve and newly installed system for their majority.

Just my .38 (v)cents.

I’m not so sure…I don’t think software that is broken or breaks other stuff improves the newcomer experience, even if it is easy to use.

That is true. But it provides an easy way to dual-boot for newcomers and serves a purpose, I think. All the dread inescapably involved, for sure.

Still, the stream of newcomers to Linux who seek help repairing after the experience of grub-costumizer doesn’t ebb, and their own experience points them to learn how grub (and Linux) work.

On a side note, Fedora and MX are pretty much up for the task to be a point-and-click adventure for newcomers from the Woondocks… :wink:

But it is potentially dangerous! Destructive!!

But, you can’t stop anyone from shooting his own feet… :person_shrugging:

hmm on EndeavourOS it will simply add windows to the bootmenu no need for extra tools :wink:

Yeah, that is a late feature, and a truly great one it seems!

I can’t try it and no long-term user-experiences can be in, during such a short time since the latest ISO release of EnOS, yet. But it sure sounds great. - Superhuman! AI-like!!!
