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

very happy of this piece of software, it does exactly what it says on the tin!
I have a question about the license, though: are a number of updates included?

I accidentally deleted the DVD optical drive from the Hasleo UEFI boot sequence and my DVD drive is no longer available for use.  According to Device Manager The Windows 10 registry data for the device has been corrupted and the drive is no longer working.  The DVD drive is not listed among the devices in the BIOS.

I tried reinstalling the device driver, but that did no good.  How can I make my DVD drive operational?

Hi

I used Windows Upgrader to let windows run an update on my Windows 10 ext USB. However somewhere in the middle of the process it hung and seemed to fail. I can no only boot into safe mode. Any ideas as to how to proceed to repair that or am I sunk and format and new installation is the only option?

regards

Martin

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
