My PC main boot drive has several O/S on it, (EFI - Tumbleweedsda4/Ubuntusda6/Windows10sda3 + several data partitions, and another windows11, on another disk.)
Want to setup so the Tumbleweed boot manager controls all.
Currently, Ubuntu ‘seems’ to control the boot. If I start the boot menu of the PC I can select to boot tumbleweed-secure and all is OK.
How do I edit/reinstall such that the tumbleweed grub is priority?
Thanks.
@hornetster either via the system BIOS boot order, or efibootmgr and set the order via the -o option…
Looking closer looks like you have a mixture of Legacy and UEFI?
Which bootloader?
Sorry, Grub2.
grub2 is not EFI. You need to explain your configuration in more details.
GRUB2 for EFI…??
Thanks all.
Good description here, as well… https://youtu.be/WVqnfNheRj8?si=Raa2k31odRaWA9vV
But still an issue…
All seems to work OK, except booting Win10 from the Tumbleweed menu, results in Win10 stealing the #1 position in the boot order… ie boot Win10, a reboot results in Win10 booting again, with no boot options.
If I then use the PC boot options to select the Tumbleweed Boot Menu, all is good until I again select Windows10, and it steals the priority boot again…
Strangely, booting Win11 retains the Tumbleweed boot menu for ensuing boots…?
Thanks.
Show I/O from running efibootmgr.
sudo efibootmgr

Fast Boot?
Nope. Just double checked…
Do you have the Win11 disk connected full-time? If yes, can you reproduce the problem after disconnecting it?
What exactly is Boot0005*?
Confession: Probably historical - Purchased the ‘refurb’d’ PC, with a 256gb NVMe, and have added the HDD, and SSD, so would be the DVD in the old PC…
Yes, Win11 connected all the time… (NVMe).
I would remove that entry with efibootmgr. Some BIOS don’t manage obsolete entries as they ought. If that doesn’t change anything, then try disconnecting the Win11 drive long enough to see what results.
Done. Will see how I go. Thanks.
Is there anywhere that can guide mo on the interpretation of the entries in those boot options?
Thanks.
Oh… And my other problem is the only way I can reboot/shutdown at the moment, is to do it from a command prompt.
None of the GUI shutdown/restart buttons are working??
And how is it related to the “placement of boot loader”? Start new topic and at the very least explain what GUI you use and what happens.
