Solved, was able to clone the boot usb before it broke definitely using: dd if=boot.img of=/dev/sd(letter new boot USB) conv=notrunc been boot.img the image of the old usb stick where I installed the boot partition when I installed Qubes. Without the conv=notrunc it didn't work, just if someone face a similar problem. Like I said in the previous message the chroot - grub-install process didn't work for me, maybe because I use FDE and been the boot partition in a separate USB. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

Standard things should work: 1. Boot from installation media (rescue mode) 2. Agree to mount the system 3. Chroot into /mnt/sysimage (chroot /mnt/sysimage) 4.

[qubes-users] Recover broken bootloader
My laptop has started to fail to boot my 4.0rc2 installation. This started after doing a qubes-dom0-update, but I'm pretty sure that I had rebooted the machine successfully at least once since then. The computer has now gone into a bootloop, and fails to display the GRUB screen. I can only assume that the bootloader is crashing. However, nothing is displayed on the screen. Is there a recommended procedure to reinstall GRUB when booting from the installation media?
