Recently I partitioned my hard drive, and installed Manjaro Linux alongside Ubuntu 18.04, and updated GRUB as required.

Now I wanted to reformat the partition having Ubuntu and reinstall it, but I could not get into BIOS menu on pressing F2 when the company logo flashed. The system just hangs up with an underscore on the top left side whenever I try to get into BIOS.

Note: Earlier there was no such problem.

I found this video of a guy explaining how to enter BIOS on an Acer laptop. At second 33, after the splash screen was displayed and before the BIOS shows up, for a short moment the screen is completely black and only an underscore (right above the u of Menu) is displayed:

Underscore flashing

Is this the moment your laptop stalls? If yes, it seems to me that there is something wrong with your firmware and I would try to re-flash it. Unfortunately Acer does not provide firmware updates via LVFS for your laptop (yet). So my advice to you would be to boot Windows and follow the steps explained in this Acer tutorial.

Follow this tutorial to create a bootable Windows PE USB drive. However, you need a working Windows system (e.g. a VM or another PC) first. Afterwards you have to add an entry to your bootloader to boot it.

If you get an error, telling you that the BIOS you try to install is not newer than the BIOA already installed, you can try this:

  • Unpack the downloaded .exe file using a tool like 7-zip or unrar.
  • Find and open the platform.ini file with a text editor.
  • Search the [Bios_Version_Check] section and replace flag=1 by flag=0
  • Run the InsydeFlash.exe as administrator.
