I’m trying to install Windows 10 into virtualbox on Ubuntu 18, however when trying to first boot up it says Press F12 to select boot device
and then switches to this screen and flashes a green and blue background
I’ve tried enabling and disabling 3D/2D acceleration.
Why isn’t it working?

Could you please elaborate a bit on what you are trying to do? Do you have an iso image of Windows 10? How did you configure your vbox? – FloT Jan 31 '19 at 23:03
-
Yes I do. And I configured it with a dynamic drive. I gave it 1/2 my ram, 2 of 4 CPUs. – Mark Deven Jan 31 '19 at 23:10
-
Did you try to press F12 at virtual machine startup to see the list of available drives? Did you try to choose W10 iso manually? Would you please post pictures of virtual machine system, display and storage? – FloT Jan 31 '19 at 23:16
-
Yes. The only one with anything on it is the disc drive. And sure – Mark Deven Jan 31 '19 at 23:17

Just in case - Ubuntu has a nice screenshot tool ;) – FloT Jan 31 '19 at 23:19

It’s a friends pc so I’m not logged in on there. Sorry it’s from a phone :) – Mark Deven Jan 31 '19 at 23:20

No problem, your pictures are good, I just thought it would be more convenient for you. On pictures, I see that Monitor count is set to 2 in display settings. May I suggest to switch to 1? And may I also ask for a picture of "storage" tab? – FloT Jan 31 '19 at 23:26
-
I tried both but sure – Mark Deven Jan 31 '19 at 23:27

Nothing shocks me in your settings... Did you try to start with only 1 monitor? Same result? Now I would suggest to check you ISO file. Did you have a chance to check it's integrity? For example with md5 checksum? Would you have an option for testing it on another computer/VBox? – FloT Jan 31 '19 at 23:42
-
I copied it from a computer where it works, but I’ll check it. Thanks again. – Mark Deven Jan 31 '19 at 23:50

Ok. Just in case, and depending on what you'll need to do with W10, Microsoft provides virtual machines ready for use on: https://developer.microsoft.com/windows/downloads/virtual-machines – FloT Feb 01 '19 at 00:01

Does it require activation/money? – Mark Deven Feb 01 '19 at 00:02
-
No, but it is temporary and for educational purpose. – FloT Feb 01 '19 at 07:45

Okay, so it wouldn't work for this project. – Mark Deven Feb 01 '19 at 19:00

Did you ever solve this? I'm experiencing the exact same thing right now on VirtualBox 6 on MacOS – MikeC Oct 01 '19 at 12:13

1Thank your comment and share answers I solve the problem. What I do is I just create new and I notice the version W7(64 bit) and change that to w10(64 bit) and the other process is the same and I start and it wo – Jan Ryan Relunia Sep 28 '22 at 15:11

I just ran into this checkerboard issue while trying to setup a Windows 10 Enterprise (version 2004) VM with VirtualBox 6.1.
When creating the virtual machine, VirtualBox incorrectly detected the VM as a Windows NT 4 install instead of a Windows 10 install resulting in the checkered screen on boot. To fix this, go under Settings -> General -> Basic and verify the version is correctly set to Windows 10.
Boots properly into the installer after changing this.

5I had a similar issue. In my case, the VM had reset itself to "Windows 10 32-bit", while I was trying to install a 64-bit Windows image. The weird thing was that I did select 64-bit in the VM creation wizard! – dovetalk Jun 22 '20 at 17:22

I had a similar experience and I'm also 100% sure I had selected the 64 bit version. However, setting it back to 64 bit did not actually help. Deleting and recreating a VM worked, however. – YoungFrog Jan 25 '21 at 17:54
Had a similar issue. Fixed it by changing the version from 32bit to 64bit.
Settings>>Basic>>Version
I had this same problem and finally solved it by starting from the beginning. I deleted the Windows 10 .iso and re-downloaded it. I guess the one I was trying to use was corrupted. Then, I removed the VM that I previously created and deleted all its files.
You can get the iso here: https://www.microsoft.com/en-in/software-download/windows10ISO
I assume you know the rest; but, if not, I found this guide helpful: https://itsfoss.com/install-windows-10-virtualbox-linux/

1I did a checksum ("Verify your download"), and it matched; so I kept the fil. Re-creating a new VM still worked for me, but I made sure the name had no funky characters, and gave it 4 G of RAM instead of 2 G. "computers are weird" is a good summary of this experience. – YoungFrog Jan 25 '21 at 17:52

Indeed, the file may have been corrupted. There are tools to verify this (sha256 checksum), before doing the (gigantic) download again; they're even advocated on the download site. – xtofl Jun 12 '21 at 09:30
Same problem here. After hours reading forums, I discovered the cause root was Intel Power Gadget. After removing, all worked fine.

The solution for me was that, under the system tab, I needed to enable i/o APIC.
I wish I could upvote this, because, while I'm sure some of the other solutions worked for others, I'm guessing that this will be the problem for 90% of the folks that visit this page.
I had a similar issue, but ultimately not the same cause.
Ultimately it required:
- More than default RAM/CPU
- VRam set to at least
128
and be set tovboxsvga
Below is the snippet of packer hcl2 I was writing that I was able to use to get things working. Hopefully this helps the next person running into this issue to get off the ground.

# Find this via: `VBoxManage list ostypes | less`
guest_os_type = "Windows10_64"
iso_url = "https://software-download.microsoft.com/download/pr/19041.264.200511-0456.vb_release_svc_refresh_CLIENTENTERPRISEEVAL_OEMRET_x64FRE_en-us.iso"
iso_checksum = "sha256:f1a4f2176259167cd2c8bf83f3f5a4039753b6cc28c35ac624da95a36e9620fc"

I was having the same issue. I just deleted the VM and created it again. No need for downloading the image again. Actually I checked the ISO's SHA256 hash and it was just fine.
I downloaded Windows 32-bit for VBox and selected Window 10 32-bit. However got same issue. It's fixed by selecting 64-bit
