Bootcamp ACPI_Bios_Error Windows 10 installation

Hi Loner,

thanks for your your suggestions.

I backed up via time machine and deleted everything via command+r

then reinstalled catalina (this took forever)

I installed windows via bootcamp + tried via several USB start sticks

No Success! Still always the same error!?

I am desperate - what is going on? It worked before for years why suddenly

I can't install windows anymore...

Please help?

What I mean is:

I used your method - no success

then also tried a USB stick with windows installation + Bootcamp windows drivers (I restarted pressed "option key", chose EFI (from USB) and again I got ACPI BIOS error.

No matter what I do it is always ACPI BIOS Error.

yup here we go:

Hm are you sure we're looking in the right direction here?

I am thinking it could be Bootcamp no correctly supporting win10 in some way atm?

I just wonder why not even when I EFI boot from an external USB stick I can not even get into

Windows recovery etc. It is always immediately ACPI_BIOS_ERROR.

"If Bootcamp installer comes up, then BC is not the issue."

Not sure it comes up but never completes - I mean I don't know what the thing does - on first reboot, its ACPI BIOS ERROR. Then it leaves the Bootcamp partition there but empty.

Could it be that the switch from HFS+ APFS in newer macbooks could cause this?

Hm I tried installations mostly with the Macbook being plugged in power supply - sometimes without (on battery) - in both cases it is again ACPI BIOS Error showing up.

Ok I used the USB to hopefully get into the windows recovery mode or repair mode to try and fix this from the

Win10 side. But it doesn't let me - I tried so many win10 versions (see original post) on usb all I see is the Windows logo then ACPI BIOS ERROR. Not a chance to even try repair anything on that side.

Ok I tried this and no problems installing on an external; then booted macbook with option key

to select the external disk; no success it doesn't detect it / doesn't show up;

I only have Ubuntu and MacOS to choose from;

I also tried to use Rufus to create another win8 and win7 usb install medium; both successfully created;

win8 on boot (option key) is detected then once selected after a while blue screen with some percentage displayed and ACPI BIOS ERROR as the reason; only stays 2 seconds then reboot;

win7 is also detected at boot (option key) once selected black screen nothing happens.

One more question.

MaxOS boots normally, any windows attempt fails because the ACPI error.

I read on many forums (windows based) you can disable acpi in the BIOS.

Now macbook/macOS doesn't have a BIOS it used stuff from the EFI partition yes?

What if I delete the EFI volume / partition?

Hi I am now on Mojave - same issue again - no success.

I don't know what is going on?

This is what Coconut Battery shows:

Hi I can confirm:

Ubuntu 19.x 64bit successfully installed and running without issues.

I can select it via option key on boot.

So why is Windows not working....no windows at all....

Yes no matter what I do Bootcamp w10 or usb w10 I always immediately get ACPI BIOS ERROR.
