I have has Win 10 Pro (WIP) version 1607 on my PC, since its release a year ago. I upgraded from Windows 7 and install went well and updates have been installed without problems until build 14367 was released, 3 days after 14366. 14366 with no problem, but beginning with 14367, I get an error. First it comes up with"Issues found" with a 'Fix Issues' button. when I click the button, it tries to install the latest update, now 14385. I get the same error I got with 367, 372, 379, 383, and now 385. "You cannot install Windows 10 with USB Flash Drive using Setup"
Windows 10 is installed on my root drive c:, and has been from the beginning. I have no USB drives containing Windows 10 (except external hard drives with copies of the original ISO file, which is not a bootable drive) I have gone into BIOS and deleted or disabled, all boot drives except my root drive. I have disconnected ALL USB devices and tried to install, but get same error. I read here to correct this make the Primary Drive active (Root drive already active) this did nothing, still cannot update. As noted, all updates up until and including update 14366 were successful. 3 days later, 14367 was released, Trying to update to 367 is when the error started.
Why does it 'think' there is a USB flash drive with my Windows 10, and why does it 'think' I am using 'Setup' to run it?
I have been posting this on the Insider Hub since June 18 when 14367 was released, I have posted here, and on the MS Windows Answers forum. I have not received a single response. I have looked through all the posts here, but most having this problem are trying to upgrade TO Win 10, I have been running Win 10 Pro Preview as an Insider, for over a year, with no issues (other than beta glitches in the OS itself) until 14367 was released on June 18. Since then I have been unable to update, With "we have found 'issues'" and the 'Fix Issues' button, that obviously does nothing. Surely there is a way to divert these updates to the Operating System being used from my ROOT drive with NO USB drives attached, except backup drives with ISO files and File History files.
