I have windows 10 home edition. I checked my hyper v capabilites of the machine.all four of it says ÝES. Should I get the docker for windows or the toolbox. I am confused.
See official guide: just follow them, don't try to make any hacker as I think this maybe waste effort to do that. For you, choose docker toolbox please.
README FIRST for Docker Toolbox and Docker Machine users: Docker Desktop for Windows requires Microsoft Hyper-V to run. The Docker Desktop for Windows installer enables Hyper-V for you, if needed, and restarts your machine. After Hyper-V is enabled, VirtualBox no longer works, but any VirtualBox VM images remain. VirtualBox VMs created with docker-machine (including the default one typically created during Toolbox install) no longer start. These VMs cannot be used side-by-side with Docker Desktop for Windows. However, you can still use docker-machine to manage remote VMs.
System Requirements:
Windows 10 64bit: Pro, Enterprise or Education (Build 15063 or later).
Virtualization is enabled in BIOS. Typically, virtualization is enabled by default. This is different from having Hyper-V enabled. For more detail see Virtualization must be enabled in Troubleshooting.
CPU SLAT-capable feature.
At least 4GB of RAM.
Note: If your system does not meet the requirements to run Docker Desktop for Windows, you can install Docker Toolbox, which uses Oracle Virtual Box instead of Hyper-V.
You won’t be able to use Docker Desktop for Windows Home edition. Docker Desktop supports professional edition not the home edition. The only option you have is Docker Toolbox.
Enter to your BIOS, and try to enable Virtualization Technology(Vtx) or AMD-V

I want to ask about cross platform compatibilty of Docker ,means if an application is designed to run in a docker container on windows,then can it run on linux or vice -versa?
Docker was create to run on Linux, so the short answer is yes.
The Windows version isn’t stable or recommend (Docker for windows). At least not by now.
“But, Fischer, I use Docker on Windows!” Yes, with WSL (windows subsystem for linux - Some kind of VM), which you can configure to set a memory limit, using the .wsconfig file, and if you look at your Windows Menu you may found a Ubuntu icon, that connects you to the bash.
Docker is largely used for people that develop software, and today many languanges and frameworks use linux, even Microsoft with .Net runs on Linux.
Docker was created to resolve one simple issue: "But it works on my machine." So, it means that a container should run on every platform. At least "it works on my computer" lol
I think the question is regarding a Windows application. If that's the case, a Windows application cannot simply run on Linux containers. For example, .Net Framework doesn't run on Linux. If an application was targeted for Windows, it needs to run on Windows and in that case only a Windows container can run the application.
Docker Desktop can run both: Windows containers and Linux containers, just not at the same time. You have to switch the context so Docker Desktop can target either WSL (for Linux) or HCS (for Windows).
I am new with docker.
I have downloaded docker desktop 4.3 version and installed when I start it
give error can not enable hyper-v service.
however windows hyper-v and container are enabled in windows features and BIOS also I enabled the hyper-v using powershell to start automatically.
I searched two days but not found solution answer.
I just installed Docker after upgrading my Windows 10 Home x64 to the version 2004 with the OS build 19041.264 (I needed to upgrade because Docker required me to have an OS buld >19018). Now if I want to launch docker I get this error Hardware assisted virtualization and data execution protection must be enabled in the BIOS. I have already read this (it is old) question, but because they let me install docker on my windows 10 home I assume that I can somehow run it without hyper-v, cuz I can't download it.
The Hyper-V role cannot be installed on Windows 10 Home. Hyper-V is used to run Linux kernel on Windows.

The alternative solution is you can use Virtual box instead of Microsoft native Hyper-V. Docker toolbox comes with Virtual box. You can get details installation steps from below link.

You will need Windows 10 Pro to run docker. Home edition is not useful for the purpose.
On a physical server with Windows Server 2019 Enterprise, I created Hyper V multiple VMs, both Servers and Win 10 Pro client.
I installed Docker Desktop (for Windows) on one of the Win 10 Pro VM clients.
The client virtual machine name is the Hyper-V Manager. I get an error when I try to start DockerDesktopVM, and the state remains off; any Docker command crashes Docker.
My questions:
Is there a conflict when nesting Hyper-V managers and VMs on the physical box?
How can you execute any docker commands when the DockerDesktopVM is off and cannot be started?

Q: How Do I Enable Nested Virtualization for Hyper-V Virtual Machines
A: Pass $true for Set-VMProcessor’s “ExposeVirtualizationExtensions” parameter
Set-VMProcessor <VMName> -ExposeVirtualizationExtensions $true
According to Docker FAQ
Docker Desktop is not supported in nested virtualization scenarios. It
might work in some cases and not in others.
https://docs.docker.com/desktop/faqs/general/#can-i-run-docker-desktop-in-nested-virtualization-scenarios
It should work even on AMD, according to MicrosoftDocs/Virtualization-Documentation issue 1276:
"Run Hyper-V in a Virtual Machine with Nested Virtualization"
Prerequisites
...
AMD EPYC/Ryzen processor or later
The Hyper-V host must be Windows Server 2022/Windows 11 or greater
VM configuration version 10.0 or greater
And:
What's new in Windows Server 2022
Nested virtualization is a feature that allows you to run Hyper-V inside of a Hyper-V virtual machine (VM).
Windows Server 2022 brings support for nested virtualization using AMD processors, giving more choices of hardware for your environments.
More information can be found at the nested virtualization documentation.
As you all know Docker runs natively on windows 10 OS. This requires Hyper-V to be enabled. I did that and docker is running fine on my win 10. I wanted to run a 64 bit linux VM on my win 10. So I downloaded the oracle virtual box and ubuntu iso and when I opened the oracle vb it was showing only 32-bit guest versions. When I checked the online info, it recommends to turn off the Hyper-V for 64-bit guest versions to appear. I did that and was able to install the 64 bit ubuntu VM on my win 10 but it broke my docker running on win 10.
Is there any way where we can have both docker running and 64 bit virtual machine installed and running on my guest win 10 OS ??
It is not possible to run Hyper-V and Virtualbox at the same time. If Hyper-V is installed on the system then VT-x is not available for VirtualBox.
I have heard of workarounds, that make switching easy, but you have to reboot the system every time.
Ubuntu is supported on Hyper-V. This question on Microsoft forums suggests Hyper-V doesn't really care if you install a 32 bit or 64 bit OS in the virtual machine.
There are a lot of tutorials online on how to create a Hyper-V Linux virtual machine, 5 steps to create Ubuntu Hyper V Image seems as good as any.
Is there any way where we can have both docker running and 64 bit virtual machine installed and running on my guest win 10 OS ??
Double-check with VirtualBox 6.0.x (starting Dec. 2018):
the ten-years old ticket 4032 "[feature-request] Nested Virtualization: VT-in-VT" is still active
there is now an "experimental feature":
2.34. Using Hyper-V with Oracle VM VirtualBox
Oracle VM VirtualBox can be used on a Windows host where Hyper-V is running. This is an experimental feature.
No configuration is required. Oracle VM VirtualBox detects Hyper-V automatically and uses Hyper-V as the virtualization engine for the host system. The CPU icon in the VM window status bar indicates that Hyper-V is being used.
Note
When using this feature, you might experience significant Oracle VM VirtualBox performance degradation on some host systems.
