Welcome to Dell Tech Support. Sometimes your system refuses to boot into Windows after starting up. In this video we will go through some basic troubleshooting to determine why your PC is not booting and help to resolve this issue. First we need to verify if you are experiencing what is called a ‘No Boot issue’ and not another type of failure. Check if the computer completes the POST which is the initial power up: it is the Power-On Self-Test. If the computer advances past the Dell logo splash screen, but then hangs when attempting to load the operating system, then it is most likely a No Boot issue. If this is the case, it is best to run a hardware diagnostic. Watch our tutorial on running the ePSA test which you can access at the end of this video (Diagnose Hardware Issues on your Dell Computer https://youtu.be/rMBIyeelQA0 ). If all the diagnostic tests pass, reboot your system and take note of any specific error messages. If there are some, contact us and we will help you with a resolution. You can also check to see if the peripherals are causing interference. With your PC off, unplug all external devices, such as USB drives, printers, cameras and phones. For desktop computers, it is okay to keep the monitor, keyboard and mouse connected to the system. You should also remove any external media like DVDs and CDs and memory cards. Restart your PC to see if it is able to boot. If it can you are good, but you should check which peripheral is the culprit. Test each separately by restarting the system with only one connected at a time. Another thing to try is to reset the BIOS back to default values. Restart the computer and repeatedly press the F2 key at the Dell logo until you enter the system setup. Look for an option reset to default settings. Then save and exit. If your system is still unable to boot into Windows, you can reset your PC or restore it to factory settings. Watch these topics for information and access these at the end of this video (How to Perform a System Restore https://youtu.be/j5OZPb0Wdp4 and Creating a Recovery Drive in Win10 https://youtu.be/FQA2LrSvMtg ).

I am booting my computer then I restart my computer but it can't open it shows a black screen

Subwaytacoman says:

Can you please reply and actually help instead of ignoring us cause I'm mad and I don't know what the freak you are saying we don't work at geek squad can you put it a simple way?

tellfile says:

Mine just stayed on the Dell splash screen where it says press F12 at the top. Nothing happens on F12 or F2. In my case it was just something went bad in the hard drive. I exchanged it with another hard drive (same operating system) expecting configuration problems, but it booted on it without issue. I put the suspected bad hard drive into other computer and got nothing. So it was hard drive and not hardware.

Mileena Kahnum says:

Just wanted to put this out there,this is the last email I sent them after 30 messages,just today:This is a Master Bios Password/Hard drive lock that my friends mom either put on there or does not remember,She got this from a friend that they (DELL) needs info from and she does not have that info.Email to DELL:I am most likely just going to have her come pick it back up tomorrow,as you cannot give me the master bios password regardless of the situation.This is the absolute worst support I have ever come across with any support,and you guys are the only ones I have ever had to get in contact with.Because everything else is so easy,except this.I have been doing repairs now for about the past 12 years,and I have never come across this.Example 1:Lets say I had a friend named Larry,and Larry passed away,and his mom said that he wanted me to have his laptop.How would I get the info that I needed to get back into it,if he had a bios protected password?I wouldn't because you guys are extremely backwards.Example 2:Lets say some prank hacker was to go into Walmart and somehow get into the BIOS and password protect it,now what? They cannot change their settings or maybe overclock if they wanted to,nothing without the password.Or for God sake register it in their name,oh man now they are crap out of luck eh?Example 3:I get it at a yard sale/garage sale and the original owner has it BIOS password protected? now what pay 200.00 to get it? Or most likely buy another cause isn't that what you want anyway.[end of email] Now me myself would ask before I got any kind of device from someone.
