I’m running a dual boot W10/Manjaro, and for some time my desktop computer has been booting straight into Windows and the Manjaro grub menu has been skipped. I’ve been trying to fix this, which I’ve already done a few times in the past. What I used to do was basically burning a Manjaro ISO on a USB key, booting on it in UEFI mode and then following the procedure described here for UEFI systems : https://wiki.manjaro.org/index.php/Restore_the_GRUB_Bootloader
My hard drive is using GPT and UEFI.
The issue is that I can’t boot on my USB drive using UEFI ; the option appears when I press f9 when booting ; I get the Manjaro menu ( the one that allows me to boot either using free or non-free drivers, to reboot, or to spawn an UEFi shell ) but none of the options work ;
-If I boot on Manjaro, no matter what the drivers are, I can see the kernel messages scroll, and then there’s a blinking underscore on the screen and the boot is stuck.
-If I try to select one of the UEFI shells, I get an error message saying that “loader.efi” is missing, and I have to reboot
-If I select “EFI default loader”, nothing happens and I get back to the boot menu
I can boot in legacy mode but I can’t fix my Manjaro installation’s boot doing so because the EFI variables are missing.
What I’ve tried so far :
-2 USB drives
-the checksum of my ISO image is correct, and I used it to install Manjaro on my laptop so it should be fine
-burning the iso with rufus and imagewriter, with all the rufus settings ( mbr, gpt and whatnot )
My BIOS’ settings :
-secure boot disabled
-fast boot disabled
-I tried with both legacy support enabled or disabled, but that doesn’t change anything
I’m currently downloading the Manjaro 15 ISO to see if that makes a difference as that’s the ISO I used the last time I fixed a boot issue, I’ll let you know if that makes a difference.
Do you guys have any clue how I could either boot on a Manjaro usb key in uefi ( preferred solution as I might need to reinstall Manjaro at some point even if I hope not ), or fix my installation’s boot with a legacy live session ?
Thanks for reading !
