I have an Acer Laptop Aspire E-5 573G It came with pre-installed Windows 10. I tried installing possibly every Linux OS (Ubuntu, Kali, Parrot Sec, Linux Mint) along side Win10 but didn't work. So I got rid of the Windows 10, cleared my whole hard disk and now when I try to install Linux I'm still stuck at the same point.

When I try to run live/install Ubuntu, Linux Mint, Parrot Sec I'm stuck at a black screen with a blinking underscore (_) I googled and tried with nomodest on and with couple more settings but it doesn't work.

But when I try to install Parrot Sec in fail safe mode I'm stuck on the following screen.

Stuck here in Parrot Sec in Fail Safe mode.

I don't understand what the problem actually is. I'm currently installing these OS in Legacy mode because when I try to install them in UEFI it doesn't detect any bootable device.

Seems to be a BIOS issue. This solution is from the Acer forum.

  1. Go to: http://us.acer.com/ac/en/US/content/drivers

  2. Search by Product Model: Aspire E5-573G

  3. Select the right OS and download a bios. In my case I downloaded 1.15.

  4. Run the ZRT_115.exe.  It will fail.

  5. But before you close the installer, go to C:\Users\name\AppData\Local\Temp\

  6. Search for a folder (random letters).tmp  There should be a H2OFFT-W.exe and zrt.rd file in there.  Just copy this folder and close the failing install.

  7. In that copied folder, edit the platform.ini file.


    ;[nb4-version] +


    ;[nb4-version] +

    The VersionFormat value now has XN.DD instead of XN.NN.
    This will ignore the fact that 1.25 -> 1.15 is a downgrade.

  8. Prepare for a reboot. I.e. close unnecessary applications and plug in power adapter. Because it'll happen automatically after running the installer.

  9. Run H2OFFT-W.exe.  Upon reboot, you'll see a bios installing progress bar.

  10. After that is done, press F2 during startup to get to bios.  The version should now be 1.15.

  11. At this point I set a password, turned off UEFI, and swapped my hard drive out for a fresh SSD. Ubuntu finally installed.
