Windows 10: Win 10 update always getting "Error: 0xC1900101 - 0x30018"

Windows 10 Error code 0xc1900101-0x30018



Same here, have tried it at least three times to no avail. Installation gives a BSOD after second reboot at 32% of installation (6% of apps and drivers). It tries to resurrect the installation, fails, and rolls back to original OS, Windows 7 Ultimate, in my case. On return to W7 it gives the dreaded error code 0xc1900101-0x30018. Will be following this thread to see if any possible solution arises.

Edit: During one of my attempts, I unplugged the USB drive and the Wifi USB, this did not help unfortunately.
