1. I mistakenly deleted a profile from users on the windows 10 OS. Hp 840 G4
2. I decided to do a system restore point which I choose the last system restore point but still could not find any files deleted files on the missing profiles
3. I got another pc of hp 840 g4 and installed windows 10 OS in SATA hard disk and also installed software Recovery Data EaseUS.
4. I pulled out SSD drive that I mistakenly deleted the profile from the OS on the pc
and inserted it on the newly pc that has the data recovery, to enable me access the SSD and run the data recovery
5. After running the data recovery, I was able to get old files and not the recent files
6. Then I decided to insert the SSD drive to is own pc to undo the restore point but could no longer access the system with error message "No bootable device found.
Question
1. Please how can I gain access to the OS and do a system restore point, to the point were the profile was mistakenly deleted ?
