I am somehow very desperate. Since yesterday, my Lenovo Thinkpad L450 is not booting Windows 10 anymore. Instead, I only get a blinking white cursor in the top-left corner on an entirely black screen. This happens before I get any screen with a Windows Logo or similar, so I cannot enter safe/recovery mode.
I also tried booting from a USB stick with the latest Win 10 image. However, the laptop does not seem to boot with that at all...
Thinks I already checked/tried:
- The USB Stick with Win 10 should work IMHO. At least, it worked on another computer, i.e., I could successfully boot from USB, but not on my laptop.
- Ubuntu boots just fine from USB on my Thinkpad.
- All hardware checks running within the firmware-integrated Lenovo Diagnostics pass, especially also for RAM and SSD. (I think this is also confirmed as the Ubuntu live image runs fine and I could access all my files from it...)
I'm afraid I don't have any other starting points for what I could try and already spent hours on this. Does someone have an idea? I appreciate any help and comments!
