Only windows boots after dual-boot installation

I installed Manjaro succesfuly on my ssd/efi hard disk besides windows 10. Trying to reboot, I found out that windows boots as usual. But where is Manjaro...???

Thanks. So I tried to press F8 while booting but in the apeared menu there was only one option to choose: ´windows boot manager´.... Why that?

Long story...
Use this Tutorial to repair/configure Manjaro EFI option


fastboot in windows is disabled?

Something went wrong and now I cannt boot into the installed Manjaro;

  • With the live CD I booted into manjaro ( grub> search.file /etc/manjaro-release root
    grub> configfile /boot/grub/grub.cfg )
  • In the installed manjaro I followed the above tutorial with the UEFI - additional commands. (there was a wornning apearing in the terminal, it looks that it was a very bad idea to ignore it and reboot the system...)
  • After rebooting, again, only windows booted. With the live CD I come to the installed Grub-menu but Manjaro doesnt boot(errors...)

What was the warning?

Since it's a fresh installation, it might be better to re-install and next time follow the tutorial to fix grub UEFI option.
Without an error description it is not possible for anyone to help you, unless out of guessing.. :thinking:

OK, thanks, I´m going to reinstall now. In which partition is actually grub installed, in the 100 mb efi or in the following windows -C partition which has the boot flag? i guess the C partition, no?

This is not a proper description for UEFI installations.
During the installation, you need to select the 100MB fat partition as $esp (flag) and mount it at /boot/efi

So I installed Manjaro again. The wornning in terminal apears after adding the uefi additional-commands in step 6:

$ sudo efibootmgr -c -d /dev/sdb -p 1 -L "manjaro" -l "\EFI\Manjaro\grubx64.efi"
efibootmgr: ** Warning ** : Boot0001 has same label manjaro
BootCurrent: 0002
Timeout: 2 seconds
BootOrder: 0003,0001,0002,0000
Boot0000* Windows Boot Manager
Boot0001* manjaro
Boot0002* UEFI: TSSTcorp CDDVDW SH-216FB
Boot0003* manjaro

It looks like Manjaro was already in the boot menu options.
The warning was just info for same labels (you could give a different label name).
Reboot and if still Manjaro is missing, you may try one of the workarounds.

From multiple installs. OP might want to take a good look at straightening out the partition tables, with the idea being to preclude future problems.

That´s weird, Manjaro IS in the boot menu BUT sometimes its booting and sometimes (mostly) not. When not, the boot proccess is ending with a black screen so that I must unplug the pc in order to be able to reboot.

Random errors are not nice.
When you boot fine get some info to help repair properly

inxi -SGopuxx
mhwd -li
cat /var/log/Xorg.0.log
cat /var/log/Xorg.0.log.old
efibootmgr -v

Edit: corrected Xorg-log paths (sorry..)

That's not weird, it's expected.

That's weird, but nothing to do with grub or the issue at hand.
One had reported he/she need the pc (you mean laptop?) to be plugged (the mains?) to boot.
The very opposite of yours. I told him/her the battery could be weak. He/she was not amused.
I don't know what to tell you or to amuse you.

So here are some info´s:

What is computer make and model?

Well, as you see I´m not a computer expert, when I get in trouble (screen freezes or so)I use the keybord/key combination to shut down. in this case it doesnt help, or maybe I just don´t know an alternative to repluging the electricity of the pc...)
