BSOD when upgrading Windows 7 to Windows 10 build 2004 (errror 0xC1900101 - 0x40021)

2

I have tried to upgrade my Windows 7 machine to Windows 10 Build 2004 and it blue-screens at around 75% with the following error code:

0xC1900101 - 0x40021
The installation failed in the SECOND_BOOT phase with an error during SYSPREP_RESPECIALIZE operation

I tried running the SetupDiag.exe utility provided by Microsoft and got the following output:


SetupDiag was unable to match to any known failure signatures.

I also googled around a bit to try to find a solution. Many people with the same error said the error lies with a USB dongle driver called aksdf.sys. I downloaded this utility: http://cbstechnology.co.uk/downloads/haspdinst_7.100.25990.1.zip and ran the included program to uninstall it, but when I ran haspdinst.exe -info (haspdinst.exe being the included program) it told me none of the relevant services or drivers were installed on my machine. So of course it is not possible to uninstall them.

I have been unable to find any more information about why this install is not working. What could be the cause, and how could it be resolved?

Thanks.

The solution was to update my BIOS. My BIOS was from 2015. If I had to take a guess, the problem was probably that I didn't have some microcode update and that was causing the Windows 10 installer to BSOD.

In my case, my motherboard is an ASUS Maximus XIII Gene. So if you are experiencing this issue and have the same motherboard, try flashing your BIOS.
