(If you have one set.) When you are finished troubleshooting, you can exit "Safe Mode" restarting your computer.
On reboot its common to see symptoms such as No Boot, Stuck at the Dell Logo splash screen, stuck at the Boot Options splash screen or error messaging such as Boot List Missing in the BIOS after the OS crashes in Windows 8 and 8.1. Do not do a "Reset" as that will wipe all data you have on the laptop. This choice will keep your data, but any programs installed will be lost. NOTE: You will need to get into the "Advanced Options" in order to get the "Refresh Option". As soon as you see the rotating loading circle, press and hold the Power Button until the computer shuts off. Repeat this process a few times until you see the "Preparing Automatic Repair" screen. Now you want to let the laptop boot to the "Automatic Repair" screen. Click "Advanced Options" and then select "Troubleshoot". Here you want to select "Refresh your PC", if you do not wish to erase data, or "Reset your PC" to erase all data and restore your system. From here just follow the screen instructions until the recovery is completed.It goes to something that says recovery and it says your pc couldn't start properly..I tried your method 10 times and that's all it said. Well if anything was trying to update when the original problem occurred (Windows 10 updates no matter if you agree or not), the the computer will continue to try to access and install that update until it has no way to do so. If there is Wi Fi in the area, turn it off, or move to another area. If an update was part of the problem, that should resolve it. If it loads in "Safe Mode" then there may well be something on the computer that shouldn't be. If that is the case, you will need to find and remove the problem before you can start correctly.(In "Safe Mode" with "Command Prompt" starts Windows in Safe Mode, with a Command Prompt window instead of the Windows interface. If neither of the above help, and it is giving you this much trouble when it is new, then I would contact the manufacturer.This option is mostly only used by IT professionals.) Now sign in to the computer with your account name and password. Immediately after turning on the computer, or restarting it (usually after you hear your computer beep), tap the F8 key, repeatedly, in 1 second intervals. The computer will then display hardware information and run a memory test. They will either have a quick solution for you, or be able to repair/replace it.The troubleshooter works through its process and then lets you know whether it could identify and fix the problem.Most of the time, the troubleshooter can successfully remove a stuck update from the queue. Even if the troubleshooter says it couldn’t identify the problem, it’s possible that the actions of starting and stopping the service and clearing out the cache did the trick.
