This question already has an answer here:

I need to add boot parameter "pci=noaer" on my live persistent usb itself. Applying this command in terminal gave a error.

sudo update-grub

Error: /usr/sbin/grub-probe: error: failed to get canonical path of 'aufs'.

I am first time Linux user, my laptop is gone for repairs and I borrowed my dad's laptop. I just wanted to browse the internet. It took me 8 days and I am still not able to achieve this basic task. Actually I am having issue with wifi card "rtl8723be" ,its a known bug.

"sys.log" and "kernal.log" floads with pcie error and it basically fills my pendrive with those two large files which makes its unbootable. At this moment I hate Linux with passion. I willing to learn and understand more about Linux but I need this system to work urgently. Please guys help me.

For me, I just needed to install grub.

sudo apt-get update;
sudo apt-get install grub

This command works fine now -

sudo update-grub
