Windows 10: is it possible to start win10 from USB (without installing o.s.)?

I created a bootable usb key with windows10 following this procedure.

How to create a Windows 10 USB bootable media with UEFI support | Windows Central

but when i turn on the pc, it lets me choose between installing win10 with or without keeping my files..

I thought it was possible simply to start operating system directly from USB...

someone can clarify me that?

thanks!.

Is it possible to install Windows 10 without a USB drive or DVD after purchasing it?

You can boot to the Windows 8.1 desktop, even in its expired state, download the .ISO file for Windows 10, mount it and perform either an upgrade or new install.

Step 2: Double click the ISO then launch setup.exe to start the installation from within Windows 10:

Is it possible to install Windows 10 without a USB drive or DVD after purchasing it?

I had my PC built months ago and had a trial version of Windows 8.1 installed. It had expired and about a day or two later (yesterday) I have purchased Windows 10 Pro software. I tried to install it but I can't seem to figure out how. I didn't think I need
a USB drive or DVD to install it. I thought it would direct me somewhere and then ask me for my product key. Just to be clear, I've bought Win 10 after my trial expired. I don't know if that has anything to do with it or what. But if I actually need to spend
extra for a drive/DVD, I would have bought the upgrade at a store.

So I need help with this. Is there a way I can install this upgrade without a drive? I figured it would be an internal installation and wouldn't need one. Thank you for the reply.

 

I guess, you are not talking about Windows PE (WinPE) | Microsoft Docs

The Windows to Go feature requires a USB specifically designed to support it. These are difficult to find (and expensive) most USBs aren't suitable.

If you need a bootable Windows on a USB to rescue data, then Kyhi's rescue disk works on any USB. You could also try a Linux Live USB.

From post #3 it sounds like what you really want is Kyhi's Recovery Tools referenced above.

 

Hi there

if you need a 100% full blown Windows system from a bootable USB device then you'll need Windows to GO but only available for Enterprise / corporate versions.

You could try booting windows from a VHD file on a USB stick --this has the disadvantage though that the internal C drive must at least start the boot process.

Another option but you will need a decent SSD and preferably a USB3==>SATA connection (although it works reasonably well with a USB2-->SATA connection) is to use a Linux OS on the USB - those boot easily enough and then with either Virtual Box or Vmware player / workstation bring up a Windows Virtual machine.

You'll need to have SAMBA installed on the linux OS and Ntfs-3g (to read / write NTFS Windows files).

It's a good learning curve to have a go with this.

To get at the Windows HDD's from your Windows Virtual machine you can either share them via SAMBA in which case you'll have to mount them on the Linux OS first or probably easier for beginners is in the VM is to attach the Windows HDD's as physical drives directly in the VM config.

The resulting Windows VM will be as near to a physical Windows machine as it's possible to get - although wouldn't be of too much use for serious game playing or other things that make real calls to the actual usually specialized hardware - but for typical tasks no probs whatsoever.

I always keep one of these around as I like to have Office 2016 in several languages - useful when you work on some clients sites in different countries.

On a decent laptop the response time on the windows VM is actually quite good !!!!

-- now if someone could get an instance of Virtual Box running on an android tablet so one could load up a Windows VM I'd be very interested !!!!!l

There's actually no Live version of full windows, the one you are describing is for installation only.
