Windows 10: Unable to login to Windows using laptop computer from diagnostic mode.

Hi gentlemen!I appreciate your answers but also the beer, so here a heck of lot of duplicates giving me a problem. I returned the laptop with Windows 11 Pro to service, but got the message I could be having it on a stick when returning back here.The other becomes a second PC the vendor will not sell, probably because of a credit assessment.The problem I have is no sound, so using the tablet instead having two, except also my mobile phone.Just one thing for the other or not any back or forth, so trying on next Monday instead.Thanks!

Unable to login to Windows using laptop computer from diagnostic mode.

Hi

Welcome to Microsoft community.

It seems like you're unable to login to Windows using the diagnostic mode and you don't have the PIN code for Windows Hello.

Here are a few suggestions you can try to resolve the issue:

1. Reset the PIN: If you have access to your Microsoft account, you can try resetting the PIN code.
   
2. Use BitLocker recovery key: If your C: drive is locked by BitLocker, you can try using the BitLocker recovery key to unlock it. During the startup process, you should see an option to enter the recovery key. If you have the recovery key, enter it and see if you can access your system.
   
3. Boot from a Windows installation media: If you have a separate USB stick with Windows 11 Home, you can try booting from it to perform a repair or reinstall Windows. Insert the USB stick, restart your laptop, and press the appropriate key (usually F12 or Esc) to access the boot menu. From there, select the USB stick as the boot device and follow the on-screen instructions to repair or reinstall Windows.
   
4. Contact Lenovo Support: If none of the above solutions work, it's best to reach out to Lenovo support for further assistance. They can provide you with specific instructions based on your laptop model and help you resolve the issue.
   

Please feel free to let me know if you have any further updates, thanks.

Unable to login with Diagnostic Startup enabled

So I thought it would be harmless to start in diagnostic mode in order to troubleshoot a video driver and ran into this exact problem: login screen with no login text boxes or account picture. I tried every method listed here but I was unable to resolve
my issue. I even went so far as to attempt to enable the legacy boot option (good old F8), but could not seem to get that to work from the recovery console. Finally, I restarted the laptop and let it go to the blank login screen one last time and walked away.

An hour later I returned and there were the login picture and text boxes! It appears it was just a matter of patience while the computer ran whatever it needed in order to operate in diagnostic mode. Out of sheer morbid curiosity, I attempted to replicate
the process by re-enabling normal startup, restarting, and then enabling diagnostic startup again. Sure enough, after waiting about 15 minutes at a login screen with no login area, the picture and text boxes to log in finally appeared.

I'm not sure what processes were going on in the background which caused this painfully long delay, but I guess it's just a matter of patience. At least, that was the situation in my case. Keep in mind my laptop has dual display processors and an 8GB internal
SSD (which was used for fast boot in Windows 7, but does nothing in Windows 10), so those may have been what was causing the delay.

Hi

Thanks for your reply.

I'm sorry to hear about the difficulties you're facing with your Lenovo laptop. You're experiencing multiple issues, including being unable to log in to Windows, encountering system crashes during installation, and losing partitions with data.

1. Partition recovery: If you've lost partitions and important data, it's crucial to avoid further actions that could potentially overwrite the lost data. It's recommended to use specialized partition recovery software to attempt to recover the lost partitions. These tools can help you restore the partition table and recover your data.
   
2. Contact Lenovo support: If you've exhausted all possible solutions and are still experiencing issues, it may be best to reach out to Lenovo support for further assistance. They can provide specific guidance based on your laptop model and help you troubleshoot the problems you're facing.
   

Remember to back up any important data before attempting any recovery or troubleshooting steps to avoid permanent data loss.
