I have an old laptop running on Windows XP. It's very old so the battery's messed up (it needs to always be plugged in when in use - if the power chord accidentally got loose the computer will shut off). Yesterday I accidentally turned it on while the laptop was unplugged. So I replugged it but then found that Windows could not get started now - there's a blue screen flashing then an error message saying "We apologize for the inconvenience but Windows did not start successfully...", which upon my search on the forum seems many people here experienced this too. As the texts say to choose "Start Windows Normally" if the problem came from Power Failure issue, which I guess is the case here, I tried that but the Windows would not start now - it only took me back to this screen again. I am also not able to choose "Last Known Good Configuration" also. The only option I could do is to enter Safe Mode, but once inside I'm not sure what else could be done there too solve this problem as I am unable to get the Windows back to normal mode now (it does not seem like I can use System Restore too as it says it is only available in normal mode). I already accessed Safe Mode to back up all the important files in the laptop, but am still hopingto find a solution to resolve this matter without having to reinstall Windows once again somehow.
