Windows 10 install boot loop after 75%
I tried to update my Windows 8.1 installation on my Thinkpad T61p to Windows 10. It went smoothly until it finished copying the files (75% complete). It is now rebooting in an endless loop (reboot -> Windows logo with spinning circle -> black screen -> Windows logo with spinning circle -> 75% complete message -> reboot) and I don't know what is causing the problem. I have installed the latest BIOS and tried various changes to BIOS settings with no effect. Does the installer write any kind of diagnostic log that would tell me the reason for the reboot loop? Has anyone managed to solve a similar problem?
