I am facing an issue with my Windows 10 on my laptop (Lenovo Y720 15-IKB). The boot manager does not start, there’s an endless loop of restarting and displaying the Lenovo screen again and again. To resolve this issue, I created a Windows 10 bootable USB to access repair tools etc. to see if they could help or not. I have already tried the following:
1) If I go to Startup Repair, it “logs” an error in the SrtTrail.txt file that there is a version mismatch and hence Startup Repair could not repair the PC. Most probably its because I had the latest Insider build installed and the bootable USB was of a slightly older version. I wonder if I can get a .iso of the latest build to resolve this issue.
2) If I go to “Reset” system, it says that the drive where Windows is installed is locked. Please “unlock” the drive and try again. How could I possibly unlock it, when it won’t even start. I can’t access the safe mode either.
3) I had created restore points earlier, to which I tried restoring to however, I received an error code 0x80070091. Afterwards I googled around and tried a few scripts (similar to those mentioned in this link System Restore Failed and Did Not Complete Successfully with Errors in Windows 10 - EaseUS) and the error changed to “An unspecified error occurred during system restore (0x80070780)”.
4) I finally narrowed down the problem via Command Prompt (when starting using a bootable USB and going to command prompt) to certain files and folders which “can’t be deleted”. I tried pretty much all techniques I could think of. These files were in the folder “C:\Program Files\WindowsApps”, one of them belonged to MS Office and another related to Lenovo. I have tried the following:
5) I have also tried “chkdsk” and “mbr” related repair strategies, none seem to work. Apparently, all is good based on the result of “Check Disk”.
Assuming a “Clean Install” is out of the question, what else could I do to repair / restore to a restore point?

I tried pretty much all techniques I could think of. These files were in the folder “C:\Program Files\WindowsApps”, one of them belonged to MS Office and another related to Lenovo. I have tried the following:
- Tried deleting the folder (and individual files), upon trying to delete a folder I get the message “The directory is not emply” and upon deleting a file I get “The file cannot be accessed by the system” and for other similar commands I also got an error saying “The file is being used by some other process”.
- Tried renaming the folder
- Tried changing access permissions (using takeown command etc. and retried the above)
- Tried moving the folders to another drive so that System restore could work for the C: drive
- Tried opening the folder etc. None of the above seems to work.
