Now I will discuss a Windows 10 installation problem with you, as I experienced it on a customer’s computer. Next, I will offer your solution found in the case study. The problem is: when I try to configure Windows 10, its setup speed is extremely slow.

So let’s start with the problem, the problem is; once I start installing Windows 10 on a PC, the time when the computer boots from the USB drive (Windows 10 Bootable USB) is very slow. The first window of the delivery assistant appeared in approximately 45 minutes. After 45 minutes, the initial window will appear; after selecting the language in the setup wizard, it took 30-40 minutes to move to another window. I am canceling it because I have decided that it has some problem, as the typical installation procedure does not behave this way. The PC configuration is Intel i5 2300, 6GB RAM, along with 100MBPS of internet connectivity.

I didn’t know if the problem is with the USB drive or with the PC itself. So I start to spot your own solution, here are my findings. I even contacted Microsoft support about it, but they just replied that they updated the BIOS settings to default and created a new Windows 10 USB again in the media development tool and altered its USB or changed the USB port. I’ve done all of that, but these measures didn’t work for me.

Finally, I found out his real answer. I did a deep research on it and found that the problem is with the complicated disk connection. So the first thing you need to do is change the SATA cable to a different port on the motherboard. When it does not work, then the SATA cable / power cable of the hard disk drive breaks down or sometimes the SATA interface found on the motherboard does not work. Therefore, you will need to diagnose it yourself by modifying it for one. In case you have linked any external HDD or SSD (besides the configuration unit), please disconnect it for some time. Every now and then this kind of problem occurs on the external drive.


The first thing is obvious, the problem is in the hard drive link, so fix this problem and after that slow down the installation.

Solution 1: The SATA port that the SATA cable is connected to on the motherboard may not be working properly or not working properly. Modify the SATA port: Unplug the SATA cable in the current port and then put it in a different accessible SATA port on this motherboard. There must be 4 SATA interfaces that can be found on the motherboard.

Solution 2: Unplug the SATA cable from the ends and then reconnect them properly. Do the exact same thing with the power cord that comes with the power source.

Solution 3: Simply unplug the external hard drive or SSD (in addition to the installation drive) when connected.

Solution 4: Alter the SATA cable along with your own power cable, possibly both is getting faulty.

Solution 5: Change the BIOS settings.

Solution 6: It may be because your own RAM is faulty. Please connect some extra RAM to your PC. Or replace RAM if you only have one RAM in your computer.

Changing the SATA interface is the vital solution in my situation. In case you have connected another HDD or even an SDD with this computer for backup, please disconnect it for some time. So we hope it works for you too. We have clarified exactly the same in my step-by-step manual. Follow the steps to troubleshoot the windows update error 0x80070422.
