Hi, I am trying to create a Win 10 Build 9901 WinToUSB onto a USB 3.0 attached SSD.
I'm running WinToUSB 2.0 Beta as Administrator.

When I point WinToUSB at the ISO file I get the following error:

Cannot find bootable image.(0x000000C403BF0000)

This ISO contains an install.wim in the Sources folder.

I've created a WinToUSB installation of Windows 8.1 on a SSD in a USB enclosure (it didn't like any flash drives) to study the differences, with the intention of modify an existing clone of an SATA UEFI disk to boot USB. Windows won't tolerate 2 disks mounted with the same GUID, but a clone accurate to this degree will certainly replace the original and boot.

I maintain Windows XP & 7 clones by swapping the Drive Letter & Volume Label assignments in MountedDevices between the source & destination drives. In Windows 7 the cloned bootbcd files having been Repaired to include the clone drive Disk Signatures which are then Excluded from update.

I've managed to boot a Windows 7 clone in a USB 2.0 enclosure (MBR disks) by disabling paging and modifying several system services in the clone's registry. While this will run it isn't worthwhile as performance is too poor. But demonstrates the possibility.

I'm reasonably sure since WinToUSB has demonstrated Windows 8.1 will run satisfactorily from USB, that a clone of an existing installation can be modified to boot USB. And these modifications reversed so the same clone will then boot SATA again? But lack the specific boot file & registry knowledge required yet, especially with the new UEFI scheme.

Any input would be appreciated: DES

I am trying to make a Windows 8.1 x86 portable install with your software.

The best result I can get is a spinning circle with the windows logo.

I have used multiple different installation sources.

The hardware I am using is a PNY USB3.0 64GB stick.

Not sure what the issue is.

I have been trying with 2.0 beta...I am trying 1.6 official now.

Due to office policy and protected software, I am successfully using the "system installed on external HDD" solution for more than 5 years. With Xp and Win7. But the installation was always a very tricky and complicated part, with lots of steps, a lot of time spent searching the web and different settings. Some additional advanced skills were required, not for everybody.
I have found your software recently. It worked for me with no problems. Helped me a lot. Really great job! Very nice and simple tool you have created. Thank you!

Last time I installed Win 7 Ultimate, using WinToUsb, some days ago. Easy and no problems.
But I got stuck since then in the idea of trying to install USB 3.0 support for my new system.
Before, in my previous installations, not using wintousb, I still didn't have that, it was on USB 2.0. It is ok, working. For the programs didn't feel any difference compared to a normal installation. But for the file handling, USB 3.0 can change a lot the speed.

So, as you said, Win7 is not offering support for USB 3.0. I've digged some time on the internet and found out that you can find USB3.0 drivers for win 7 and you can install them separately.
Unfortunately, there seem to be a bug in this and when you install them, before and during installation, you have to disconnect all the USB devices connected. Which is not possible running the system on a USB HDD. Logically Otherwise you will get a nice blue screen on the next boot, after installation of USB 3.0 drivers and the system must be restored to fix it.

I am thinking that a possible solution would be installing Win 7 on the internal drive and then adding the USB 3.0 drivers and then using your very new added feature "Clone current system to an USB drive". What do you think?
Since I already installed Win7, with everything, including a lot of big softwares, which took a lot of time, another possible solution in my case, it would be to clone the already installed USB HDD to an internal HDD (here I am not sure that it will work smoothly and that the win7 installation will still work), then install the USB3.0 drivers on the internal HDD and then clone back the HDD to external, or use your new added tool for that. What do you say?

Thanks in advance for your reply, and thank you again anyway for the great job with this software

Hello:

I read about WinToUSB on Lifehacker.com & was wondering if I could use my current Win laptop to clone the OS to try it out on an external hard drive.

Goal 1: Run Windows on External Hard drive when using my Mac computer
Goal 2: Run Office on the drive as well
Goal 3: Not lose current Window OS 8.1 on my second PC

Thank you for your response.

Best Regards,

Hi guys, i have a problem and i want to know if anyone has it. I'm trying to make a bootable windows 7 x64, to run it from the usb flash drive. Everything is ok until the percent reach 95 and stuck there. I left it over night for 8 hours and still 95%.
I have a USB KingstonTraveler 3.0 of 32G.
How can i install any Windows 7 and run it from the usb flash drive ? Can anyone help me ?

Thank you

I'm using a Mymemory 128gb stick and tried to install Win8,7 and Vista and I'm getting BSOD With the error 0x0000007B all the time. Any help to fix this?

Hello,
My Local HDD passed away .and I managed to install Windows 8.1
on an external hard drive thanks to WinToUSB.But Kaspersky Internet
Security refuse to be installed on that disk. Because this is not supported.
Is there any solution to that.And thank you very much for your help.

Hello,
I have been trying to install windows 7 to an external hdd and when using this program, I am unable to select the first partition option.

Hi All,
I just installed a 8.1 Enterprise on WinToGo disk.
And so I of course tried to connect the drive on several different machines, just to test if it was really working on any machine or not: of course it worked great each time.
Thus I realized something: each time you connect the WinToGo on a new machine, it will first install new files to adapt itself to the host so it can run smoothly.
Therefore each time we do that, the available free space on the disk is of course decreasing.
So here comes the question : is there a way to clean up the WinToGo drive to remove all the files which match a host we won't use anymore ?

Hoping someone will know, I thank you in advance for your feedback.

KR,
David

(Also just for information for those who would be interested : my WinToGo drive is an SSD Crucial M500 240Gb, placed in an IcyBox USB 3.0 compatible UASP.
And honestly this Win 8.1 ToGo drive works much faster than my current Win 7 x64 host system standing an WD500gb !! Really awesome )
