I installed, just to try it out, openSUSE Tumbleweed KDE 20250625 on the same internal drive (SSD) where Fedora 42 was already installed.
When I reboot now, I do not have the choice between the two, but openSUSE Tumbleweed starts always immediately.
What to do to have the opportunity to use both OS (not at the same time !) ?
Do I have to uninstall openSUSE and install it on a external drive or … ? And how ?
Please, if you see a possibility to solve my problem, present the solution step-by-step : I am not an expert !
Anyway, thanks in advance for your reply.
Best regards.
ISTR, the default /etc/default/grub contains GRUB_DISABLE_OS_PROBER="true", which needs to be changed from true to false before TW’s Grub stands a chance of including Fedora when next grub.cfg is regenerated. Also ISTR that Fedora has been defaulting to using BLS and/or systemd-boot instead of Grub. I don’t know whether bootloader type needs to match for either one or the other between Fedora and TW for automatic boot menu inclusion of the other. All my multibooting ignores automatic Grub setup. Instead it relies on the Grub option to use my personally constructed /boot/grub2/custom.cfg on TW, which would normally be employed by default via /etc/grub.d/41_custom, but on mine, a copy of original 41_custom named 07_custom is used to automatically put all (as many of 28 or so in total that actually fit the screen) custom.cfg entries atop Grub’s boot menu.
To facilitate access to Fedora until you get this all sorted to your full satisfaction, you could find the /boot/loader/entries/ entry for Fedora’s latest installed kernel and adapt it as an entry in TW’s /etc/grub.d/40_custom for inclusion in TW’s Grub boot menu. Alternatively, that entry could be adapted to a /boot/grub2/custom.cfg file on TW that you create for Grub calling via 41_custom.

Zoals gezegd, zet LANG=C voor een commando en dan wordt engelse uitvoer gegenereerd.
En gebruik alsjeblieft Preformatted text zodat alles blijft zoals het op je scherm is te lezen en niet in elkaar gedrukt. Het is de knop </> uit de balk boven het veld waarin je zit te tikken. Je kunt ook met de hand drie back quotes (die zit onder de tilde ~ linksboven op je toetsenbord) op een regel zetten, daaronder je gekopieëerde en geplakte text en dan weer drie back quotes op een nieuwe regel.
Dit is complete nonsense. Er staan hoofdletters waar die niet waren. Kopieëer en plak altijd zonder iets te wijzigen. Anders gaat er meestal iets fout en bovendien vertrouwt niemend hier wat er staat.
rodsbooks.com. I once tried rEFInd on an iMac. rEFInd worked OK for a period, but when it quit, I found it easier to return to EFI Grub2 than to fix rEFInd.
It’s my understanding that Fedora creates this partition when not using Grub for booting. If this is correct, and your Fedora is not using Grub, then reinstalling TW using systemd-boot instead of Grub may be your easiest way forward for multibooting Fedora with TW.
