I have installed Windows 10 on a Samsung T1 portable ssd using WinToUsb.  When I boot from the usb on certain computers I get a blue screen of death with the code BUGCODE_USB3_DRIVER.  Any ideas why?  On the same computers it boots fine (albeit slowly) on usb 2.  But on other computers it boots correctly on usb 3.0.

I have tried uefi and bios booting, and different versions of Windows 10, but no luck.  All the computers, both working and not, are Dell branded.  Drivers are up to date.  I've even tried making my Windows To Go install using a rival programme (Aomei), but the same error persists on the same machines.

So it seems the problem is hardware-based because it consistently works on some machines and consistently fails on others, but I would really like to know a solution to the problem.  Having a portable OS is not that useful when it only works on certain machines.

I got to the step where you select the usb drive partitions.  I have one in FAT32 and the other in NTFS and, I try to click on them but they do not highlight in red.  Leaving me with the next button still grayed out.

Thanks for the help!

I created a couple of Win 10 USB external hard drives, and am having a small question: I had to get a replacement motherboard, so, how would I go about reactivating my drives to this new system? I 'd rather not have to delete all the work I've put into them, but don't want to be without activated drives, either.

Thank for your support,

My WinToUSB.VHD is 66 GB of which my cloned C drive takes 49.05 GB and the rest is shown as unallocated space of 16.95 GB. I got to know this after i mounted this VHD. Now, why is this space there first of all, secondly is this unallocated space being used by any system ? or Is it lying just dead vacant and unused. I would like to reclaim this space if possible. I have cloned my Windows 7 Ultimate. Below is screen shot of my HDDs. Please advise.

Hi,

First off - ty for such a nice piece of software.

Second- I installed Win10 successfully on my USB drive. It works well so far using the created VHD file. It stays activated without a problem on the computer i created WinToUSB. However ...

my idea or understanding was that this way i can use Win10 on any (or many) other computers (just like Linux does). So far this seems to be the case, HOWEVER it will not stay activated ...

What would be the solution (the original computer used for WinToUSB creation has a digital license upgrade right)?

I have a minimal(28gb) installation of Windows 10 Professional & want to clone it to 64gb Flash Drive.
Flash drive has MBR with the following partitions:
winToUsb (D) NTFS 60.2g boot partition
* Fat32 100m system partition
Using mode VHDX or VHD, Legacy not available.
Starts to create WinPe then fails with error 'can not run System API (0x0000001502660000)'
I have also disabled the Firewall. Attached is user.log as text file.
I look forward for any help with this problem.

Hello , I have followed the instructions to allow hibernation in the Local Group Policy Editor (gpedit.msc), but its still not available, tried with powercfg.exe /hibernate on after, but keeps saying it can't be activated because of VHD.
How can it be activated?
How to enable or disable hibernate in Windows To Go workspace?
Thanks

I want to boot both BIOS-based and UEFI-based computers. So on my USB hard drive I created a System FAT partition(350M) and a NTFS boot partition. But it does not allow me to select the system partition. There is no radio button for the system partition. What is the problem?

I am using WinToUSB Free v3.1. I am trying to install Windows 10 Pro 64 bits. My USB hard drive is using MBR partition.

Screenshot is attached.
