If the issue gets resolved in Safe mode, then perform Clean Boot:

A clean boot is performed to start Windows by using a minimal set of drivers and startup programs. This helps eliminate software conflicts that occur when you install a program or an update or when you run a program in Windows. You may also troubleshoot or determine what conflict is causing the problem by performing a clean boot. You must log on to the computer as an administrator to be able to perform a clean boot. Your computer may temporarily lose some functionality when you perform a clean boot. When you start the computer normally, the functionality returns. However, you may receive the original error message, or experience the original behavior if the problem still exists. If the computer is connected to a network, network policy settings may prevent you from following these steps.

Follow the steps mentioned in the following article.

Method 3:

1. Press and hold Shift key and click on Restart from login screen.

2. Click on Troubleshoot.

3. Select Advanced Options.

4. Select Startup Repair and follow the on screen instructions.

Hi

Thanks for the speedy reply. I actually got it to work, I got that the error was due to communication with some of my hardware and the BIOS.

I have the newest BIOS, so I started unplugging things.

USB devices - no effect

All other hard drives than boot - no effect

In the end, it proved to be the CD-ROM drive

Disconnected the CD-ROM drive, managed to boot and install from the USB. But the installation procedure was still unstable until I unplugged all the hard drives. Now I have manged to complete the install, re-attached all hard drives and everything is working fine. Haven't reattached the CD-ROM drive yet. 

And I am not sure that there are hardware problems, this setup worked without fault in Windows 8.1 and its working just fine in 10 now, bar the CD ROM of course.
