Hello,
I'm trying to clone my Windows 10 hard drive to my external usb hard drive (both are GPT) .
I have correctly formatted the EFI Partition and NTFS Partition (EFI & Boot).
I have not used sector by sector clone as my Source HDD is 3TB while USB HDD is 1TB.

Every time i tried i just keep getting the same error after it reaches 55%, i tried reformatting the Partitions and still no success.
This error keeps coming up: "Failed to run system API.(0x0005001500F90000)".

Do you know how to fix this problem? I also have images to the screens.
I am using WinToUSB Free too.






Thanks.

I set WIndows 10 on my SanDisk UltraFit 128gb Pendrive (3.0 150mb / s) with WinToUSB.

Unfortunately, somehow everything works slowly, it's impossible to work.

Does anyone have an idea why? Install something? Any drivers? Benchmarks?

In the net I read that with a fast not obsolete USB stick in the USB version should work with sufficient speed for normal use. (my pendrive seems to be okey for something like that)

 

I do not know how to go about it ... any ideas how to start with it?

my laptop is Dell Inspiron 3721

What can I do if I have this issue : "Failed to extract file from the WIM file . Please temporarily deactivate your anti-virus software , and try again 0x000000F009590046 " . I installing the windows by WinToUsb app on a new SSD Drive .. the app is installind up to 36% than appear the Issue wroted uper and automatecally is ejecting the SSD drive !

I have no any anti-virus installed >> even Windows defender I deactivate >>> Same issue apear !
How to solve this issue ?? What shoud I add or change ?

This has happened to me twice now cloning Window 8.1 to Extreme usb 3.0 works 100%, however it seems when the space is getting low on the 64GB stick windows decides to use the paging file on the local internal drives & also changing the boot menu thinking it shouldboot from D drive & not drive C.

Hi there,

After all of cloning process, that took a lot of time, the process failed with an error 0x0079000200F90000 message (see attatchment). I was trying to clone a 1TB hdd with 482GB used to another 1 TB hdd, with 1GB Fat32 system partition and the remaining as boot partition NTFS.

Thanks for any help

I followed
"How to use WinToUSB to clone Windows 10 to an external hard drive as portable Windows 10"

System partition 200MB Fat32
boot partition NTFT of over 200 GB
Trying to clone a 100GB installed OS
Used an external SanDisk USB3 SSD drive of 250GB

Also Tried with a 500GB usb external disk and got the same error, so it looks the the size is not the issue

I've been using many different ISO's and different versions of WinToUSB but I can't seem to get it to work, either I cant boot into it or when I do boot into it I just get an error. I'm trying to get Windows 8.1 on my 32GB USB. I'm not sure if its because of the ISO or if its because the USB. If you can please tell me where I can get a ISO of Windows 8.1 or Windows 8 compatible with the latest version of WinToUSB that would be great. Or if you could tell me what to do step by step.

I cant find a fix anywhere I cant select the EFI system partition(ESP)
But I can select the boot partition.

When I try to select the legacy option it is greyed out and doesn't let me use it. I need to use it.
Thanks
