Windows 10 RTM not working

[admin]

Sorry for the possible false alarm.  But maybe this helps someone.  What I noticed:

1. Building a Win8.1 using Win2USB with Kaspersky Internet Security 2015 turned on works
2. Building a Win10 using Win2USB with Kaspersky Internet Security 2015 turned on fails.  Only by exiting Kaspersky, does the Win2USB complete like it should.

Have same problem with macbook pro. Surprisingly, also, running Kaspersky antivirus on OSx Yosemite platform. However, on windows didn't install any antivirus due to Windows Defender feature. With Windows 7 there were no issues at all. After updating to windows 10 after few days the bootcamp update came in, therefore, decided to update. However, after the update the system failed to load. Firstly, had following errors;

- System_thread_exception_not_handled
- Inaccessible_boot_error

Tried to follow most common instructions from Microsoft support and ended with;

- Inaccessible_boot_device

Was thinking to reinstall everything again but seems that it won't solve the problem because it may be due to new Windows 10 bootcamp version updates. As a result, going to recover all files from that bootcamp and back to Windows 7 for a while. Hopefully folks, you will find the solution for this and we could use Windows 10 without any startup errors.

Please temporarily deactivate your anti-virus software (Kaspersky), and try again.
You said your system failed to load, is it a WinToUSB drive?
