My Manjaro system crashed UEFI boot after PC retart.
The disk is divided into 3 partitions - boot (fat32, flags boot and esp), root (ext4) and home (ext4)
The disk is visible in the BIOS. But when starting the PC, an error appears - “Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key”
Manjaro stopped booting via UEFI, but Windows with MBR boots. If leave only the disc with Manjaro, then I get the message - “Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key”
I have a Live-CD with ubuntu and it boots fine with UEFI
This is some kind of magic, most likely you will have to make a Live-CD with Manjaro in and execute:
sudo mount /dev/sdXY /mnt
sudo mount /dev/sdXY /mnt/boot/efi
sudo manjaro-chroot /mnt
sudo grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=Manjaro --recheck
sudo update-grub
reboot
Everything is set up in the BIOS, my system has been running for almost 4 years and everything was fine. But yesterday’s PC reboot and magically something went wrong
I have Live-CD but it is with Ubuntu and I don’t want to demolish it. Seeking for a USB stick to make a Live-CD Manjaro
I can’t figure out what happened. Disk with MBR markup where Windows is loaded. Manjaro with GPT markup does not want to load. And all after restarting the PC.
If I understand the issue, and you are able to boot into windows, I had an issue where on occasion, rebooting my dual boot system would bypass GRUB and boot directly into Windows10.
Ironically, the way to fix it was from inside Windows, I am not sure if this will work in a system that has MBR & UEFI but it may work.
From inside Windows, run a Command prompt with Administration Privileges then paste the following command:
