I use Ubuntu dual boot with Windows. I recently updated my BIOS from the Acer official website for increased performance, but after updating the BIOS, I am not able to boot Ubuntu. Earlier I used the Windows Boot Manager screen to boot to Ubuntu which appeared after I pressed F12 on my laptop. The boot screen does not show the option for Ubuntu.
