Thanks for your input natakuc4. I was somehow, after a lot of attempts, able to start in my laptop in safe mode. So, all good now :)
Hi,  My laptop is throwing up a Windows recovery error (Windows failed to start. A recent hardware or software change might be the cause).  I have tried starting in the Safe Mode, but that just leads to a blank screen with a white arrow. Choosing option 'Last Known Good Configuration (advanced)' or others too lead to a blank screen. I ran the diagnostics (after tapping F12) but it didnt give any error.  Any suggestions on how I can fix this??   Thanks a lot in advance for your help :)
