Several Windows 10 users are reportedly encountering the dreaded Blue Screen of Death (BSOD) error C1900101-20017 during Windows 10 installation as the installer reboots the PC immediately after initialising the upgrade process.
It is ascertained that the blue screen error message pops up soon after the restart during Windows 10 upgrade. Then the PC restarts again, displaying an installation failure error message with code C1900101-20017.
One can also notice a subtext in the error message describing that the installer has failed in the SAFE_OS phase during the boot process. It is reported that the issue occurs due to a faulty BIOS setting.
Consequently, the BSOD issue can be resolved in simple steps by just enabling UEFI Boot from the BIOS and disabling all overclocking options for the processor.
Here is how you do it:
Step 1: Go to C: > Windows > Software Distribution > Download and delete all the files stored in this folder. Also delete the $Windows.~BT folder located in the root directory of "C:".
Step 2: As the Windows Update method seems to be a bit messy due to inherent bugs in the OS, it is advisable to try performing a clean install of Windows 10 by downloading the ISO files from Microsoft's official website. After downloading the ISO file, you need to create a bootable installation media via Microsoft's Media Creation tool.
Step 3: Once you have prepared the bootable USB drive or DVD, you can proceed with correcting a few settings in the BIOS menu.
Step 4: Reboot your computer and once the display appears, quickly tap the F12 or Delete key to bring up the BIOS menu.
Step 5: Disable all overclocking options for your processor, if you have set it higher than default values.
Step 6: Enable UEFI Boot from the BIOS, which can be found under the Boot section of the BIOS screen.
Step 7: Just reboot the computer via installation media you created earlier and the Windows 10 upgrade should complete without any hassles.
