Windows 10 TH2 Crapping Out At 40%

This is very frustrating! I tried updating my previous Windows 10 software (which had been working fine) twice now and it keeps crapping out at 40% when installing features and drivers (23%). I'm upgrading my Dell Inspiron 1545 laptop. The message is "Windows could not configure one or more system components". It then says to restart the computer and restart the installation. I don't want to do this again unless it's going to work since it takes about 1.5 hours each time so far. I prefer not to do a clean install unless it's my last resort.

Suggestions please?

There have been reports of the upgrade install stalling at 40% if there is a SD or MicroSD card in the card reader.

Hope this helps with your problem.

I read that as well. I removed the SD card and even removed my anti-virus (Avast) software. Now, for some reason, the update does not load and Windows says its up to date.

How do I trigger the update to load again?

While upgrading your Windows, Setup will try to replace drivers for your devices. If any device is found not having Windows 10 drivers on Windows Update or other known source to Setup, it will hang. Uninstall any antivirus and firewall, remove all peripherals (printers, scanners etc). Then go at Device Manager and disable any non-important device such as audio, SATA/SCSI controller without devices attached, TV tuner etc. Then press Win+R to load Run and execute msconfig. Go to Services tab and check the box to hide all Microsoft services. See the remaining third-party services and uncheck the box to disable anything non-important such as updaters. Then click on the Startup tab and click to open Task Manager. See all startup applications and disable anything non-important such as Java updater, Skype, QTtask and quick launchers. Now you should be able to run Setup without any issue.

Hi Guys

Ok, same problem for me. I get to the 40% mark (installing drivers and features) and get an error box pop up with the following:-

“Windows could not configure one or more system components. To install Windows, restart the computer and then restart the installation.”

Clicking ok then restores my previous version of Windows 10 and the following error message:-

“0xC1900101 – 0x30018
The installation failed in the FIRST_BOOT phase with an error during SYSREP operation”

I am installing from a mounted ISO (not a clean install) and for my last failed attempt I did all of the following:-

Disabled all non essential hardware in device manager, audio, camera, blue tooth, printers etc
Disabled all non Microsoft services from MSCONFIG
Disabled all non essential start programs
Switched off Windows firewall
Uninstalled AV
Disabled Net Framework 3.5
No SD card

If anyone has any further idea’s I will be happy to try. Worthy of note maybe but I haven’t been offered the update through WU and upgraded from Win7 to Win10 in September.

Thank you!

In Windows 8.1 you may also have to disable Fast startup. Open Control Panel, click View by -> Large icons to see all controls. Open Power Options and, from the left, click Choose what the power button does. Click on Change settings that are currently unavailable and uncheck the Fast startup box. If applicable, you must also disable secure boot in BIOS.

I haven't got secure boot as an option in my BIOS but have tried it all again with fast start-up disabled but still no good. Many thanks for the suggestion though, much appreciated!

For me, I solved it by unplugging the usb cable from my Dell SX2210 monitor from my computer that supported my mic and built in webcam. Then it worked. But now that I am upgraded, I get the BSOD whenever I plug it back in. Trying to solve here and on the answers.microsoft.com forums...

I haven't got any peripherals plugged in but just gave it another go, this time by updating some drivers, repeating all steps above and disabling wifi. Again no good. That was my 8th attempt and I think that I will admit defeat now, my laptop will not update from Windows 10 to erm.. Windows 10
