"ACPI: Unable to load system description tables" when trying to install

I am having an incredibly hard time trying to get Ubuntu (or any distro) to install on my laptop.

I've put a more thorough description of what I've tried here:

http://askubuntu.com/questions/67507...cer-aspire-e15

but the long and short of it is that when I try to install Ubuntu on my laptop in legacy mode (trying to do it in UEFI mode just gives me a black screen), I get an error that reads "ACPI: Unable to load description tables" and if I try to install it in verbose mode it hangs on "can't find IRQ for PCI INT A: probably buggy MP table"

I have updated my BIOS to the latest release but no luck, and I've tried installing with acpi=off and then I just get a blank white screen with a blinking cursor.

My laptop is an Acer Aspire E 15 E5-573G
i5-5200U
Nvidia GeForce 940m

Any help? I've been banging my head against this for three days now.

Your problem is not only yours. It is with everyone who is using BIOS v1.25. You need to downgrade your BIOS. I too was suffering from this problem and did the following:

Go to your region's Acer support website page.

Search by Product Model:
Aspire E5-573x (Where x stands for your specific model)

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:

Quote:

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

After:

Quote:

[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.

Now you will be able to installed any GNU/Linux distro of your choice.

Don't forget to mark this thread SOLVED!

Thanks! That actually ended up working. Of course, then it turns out that the wireless card in this laptop doesn't have debian drivers yet, but at least Ubuntu got installed.

Good info. After a whole day googling for ideas, this helped

My Acer= Aspire V15 V3-574G-77P6 : Original BIOS rev= 1.27
Available to download revs 1.15, 1.31

I first tried the newer one, 1.31 and it worked.

I can now boot Linux live CDs, I tried Mint Mate 17.1 and Navigatrix and Ubuntu Ultimate Edition 2.6

Thanks for the answer.

Wifi card is able to detect and work. See my GitHub repo for more details.
