I have downloaded the Windows 10 ISO and installed WinToUSB 3.1 successfully.  When trying to use Windows To Go Conversion on the step "Please select the destination disk", my Sandisk Extreme 64GB USB 3.0 SDCZ80-064G-G46 drive dismounts and I receive the following error: Failed to run system API.(0x00320015011F0000).  I have to go back into computer management to re-assign the drive and format it before seeing it in My Computer again.  I'm running Windows 10 Pro on a Surface Pro 4 with Bitlocker and Windows Defender activated.  I have tried turning Windows Defender off, but the same warning continued to appear.  The logs are attached.  Please advise.  Thanks!

Hello dear support team,

I tried installing various windows OS with various versions of the program on a sandisk 32 GB USB device.
However it always errors out with the well known system api error. For specifics, I put the user.log in the attachment.

I hope you can fix this issue for me (:

Best regards

I have created a win10 copy installation on a 120gb usb solid drive .
I had to use VHD to copy my current installation . Starting up was
very slow , then I started my virtual box into this XP virtual . Its
going like a train , and uses the image of the main computer drive.

I am completely confused about what I have cloned , is it just the
start partition ?

Anyway , it is MEGA .

Cheers ian

Hey guys,
i got a problem with WinToUSB. After i selected my USB Drive it show me my partitions, but i cant select them. There is a box to click but it won't. don't know what i have done wrong. In another thread someone fixed it with expanding his allocation but this didnt helped me. Some ideas or solution?

Hy,
I have a 30GB Kingston DataTraveller USB Sick. Win-to-USB formats it to only 1 partition (MBR, NTFS). So I cant go on, as the second partition is missing.

I took the stick to a Linux and created 2 partitions (Fat32, NtfS) using gparted, as Windows cant do that (i think).

BUT when I use that stick, Win-to-USB reformats it again after selection of the target device!

How to do that?

p.s.: whats the minimum size of the boot partition? (I want to install Win10 on the USB Stick).

Thx!

Hi,

I'm trying to put Hyper-V Server 2016 Technical Preview onto a USB stick / HDD but keep running into the same error - Failed to run system API.(0x0003001502890000) . I've tried Legacy, VHD and VHDX installs with the same results. Could you shed any light on this error (or advise what I've done wrong)? Log file is attached.

Regards,

Richard

Hello,

It would be nice to have support for Arsenal Virtual SCSI disk devices as destination disk. These are virtual disk devices created by the Arsenal Image Mounter tool. Currently these are not shown in the "Please select the destination disk:" combobox (probably because they are not using the USB bus).

This way it is not necessary to use an actual physical disk as destination, but a virtual one (a VHD image, for instance). These may be used within a virtual machine. Another usage example is with Easy2Boot, which can boot VHD files.

Regards,
John

Dear all,
I'm now to this great world of Windows Portable.

I've installed Win10 on a USB flash and when starting I get a blue screen with
":( Your PC ran into a problem and needs to restart. You can restart. If you'd like to know more, you can search online later for this error: MEMORY_MANAGEMENT"

Tech data:
PC: Dell Inspiron 7359, i7, 13", USB3, Win10-64 (service tag 9ZDW682)
USB flash: Kingstone HyperX Savage 256 GB, 350/250 MB/s
Installed portable OS: Win 10-64 (installed in VHDX mode); tried also Win8-64 in VHDX and VHDX, same error.

I needed to set the Boot mode to Legacy (non UEFI) to be able to select the USB drive for boot (F12 at startup).
By the way, after setting Boot Legacy mode, when I'd like to boot again with the original OS, I need to change again Boot Mode settings to Only UEFI.

Any idea?
