I have an Acer Aspire E5-573G with Windows 10 installed in UEFI mode and Linux Mint 17.1 installed in Legacy mode.

Recently I upgraded the BIOS to the latest version available in the Acer support page. After that, I can't boot to Linux Mint, GRUB shows up but Mint won't boot. Booting up in recovery mode, the process went stuck with the following error:

[0.158892] pci 0000:00:14.0: can't find IRQ for PCI INT A; probably buggy MP table

After that, the boot process freezes and the only thing showing is a blinking cursor. I really have no idea what happened here. I figured that maybe I can boot into a live USB and retrieve the data inside the Mint partition, and just reinstall it afterwards. But apparently even a live Linux Mint USB won't boot.

Can anyone please explain what is happening there, and if there's any way to fix this? If there's any material I should post just let me know. Thank you in advance! :)

At the time of this post, 1.25 is the latest version. You need to downgrade to 1.15.

The process is detailed here: http://community.acer.com/t5/E-and-M-Series/Acer-Aspire-e5-573g-You-can-not-install-any-one-Linux/m-p/386281/highlight/true#M3080

Here it is in case that link goes down:

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

Search by Product Model:

Aspire E5-573G

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

Run the ZRT_115.exe.

It will fail.

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

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.

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

Before:

[BIOSVersionFormat]
;[nb4-version] + 
BIOSVFEnable=1
VersionFormat=XN.NN

After:

[BIOSVersionFormat]
;[nb4-version] + 
BIOSVFEnable=1
VersionFormat=XN.DD

The VersionFormat value now has 'XN.DD' instead of 'XN.NN'.

This will ignore the fact that 1.25 -> 1.15 is a downgrade.

Prepare for a reboot. I.E. close unnecessary applications. Because it'll happen automatically after running the installer.

Run H2OFFT-W.exe.

Upon reboot, you'll see a bios installing progress bar.

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

Upgrading to version 1.37 of the BIOS works too, now that it's out (instead of downgrading). Tested on Ubuntu 12.04, 14.04, 16.04
