After installing the UpDate 7.1.2817 on two absolutely different configurated Workstations with Win 10 x64 leed to the same trouble:
First: Driveletters for USB device disapear
USB drives are missing in the "Datenträgerverwaltung" of Win 10
Second: A reboot ends with blue screen and INACCESSIBLE_BOOT_DEVICE" error
Win 10 repair tools do help. Only restoring the last image (before the update was made) solves the problem.
Restoring a newer image with the update already installed leads to the same problem. System does not boot with INACCESSIBLE_BOOT_DEVICE error
This issue exists since I made the update to Ver 7.1.2817 on both PCs. Without this update they work fine.
First I thought Maleware, Virus or Microsoft patches causes this problems. They do not exist (maleware, virus) or do not lead to the problem.
