Fix No Boot Issue After Windows 10 May 2019 1903 Update on Dell PC
Overview: Many Dell users are facing no boot issue after updating windows 10 to the 1903 version. Today in this post we will troubleshoot no boot issue.
So, let’s start with the real user’s practical scenarios!
Practical Scenario: May 2019 Update, Won’t Boot
Was waiting for the new May 2019 Update from Windows 10. They had an Update assistant and I thought if there was anything that did not work or not correct it would now allow my computer to be upgraded. I read about the issued with an external USB device attached so I just disconnected my external HD. Now I tried to start the computer after installation. The computer got past the Dell splash screen then hung with the spinning dots. I shut the power off and tried to start again except pressing the F2 key. I got the bios and reset it to load factory settings. I exited and tried to restart again. Nothing. I clicked F12 and got the recovery options. I went into advanced options and went to safe mode. It started in safe mode and afterward, I had the computer do a normal restart and it came up after being in safe mode. I also tried an in-place upgrade to win 10 with the same May 2019 media creation tool. Everything installed with no problems but the same boot issue. Any suggestions? I have reset the bios to defaults as well. Please help!!

Hard Reset
Unplug all external devices, try unplugging all devices from your computer. The only devices you should leave connected to your computer are your monitor, mouse, and the keyboard, if the computer is a desktop. Now Shut down your desktop and unplug the power cable from the desktop.
In case of laptop unplug the charger and remove the battery if applicable.
Now press hold the power button down for approximately 15-20 seconds then plug in the power cable back to the desktop and plug in the battery and charger back in case of the laptop and start the system. Most of the time performing hard reset fixes the issue. In case the issue still persists move on to the next step.

Run a Hardware Test to Determine Any Hardware Failure
In order to run the hardware test, start your PC and immediately keep tapping F12 key on the keyboard. It will take you to the Boot menu, use the down arrow key on the keyboard to select Diagnostic and then hit Enter on the keyboard. Make sure the charger is plugged in if you have Dell laptop. In case if you receive any hardware failure message then get the hardware replaced. I have seen cases where hard drive failure is responsible for no boot issue.

Reset BIOS to Default
Start your PC and keep tapping F2 on the keyboard to enter the system setup. Depending upon the type of BIOS the BIOS screen will be different as shown below.
If you have this BIOS screen as shown in the pic above then click Restore Settings or Load Defaults whichever is mentioned.
Make sure BIOS Defaults is selected or confirm to load the defaults and click OK.
Click Exit.
The system will restart now.
If your BIOS looks like above pic then press F9 on the keyboard to Load Optimized Defaults or Load Optimal Defaults and then press F10 on the keyboard to save and exit.
The system will restart now. If the system does not boot after the BIOS reset then follow the next step.
Correct the Windows Boot Manager Entry Under the Boot Sequence in BIOS
We have seen this solution has worked in 90 % of the cases approx. where the error is “Operating System Loader Has no Signature. Incompatible with SecureBoot. All bootable devices failed Secure Boot verification”. So, following this step should resolve the issue.
Start your PC and immediately keep on tapping F2 on the keyboard to get into the BIOS. Once you are in the BIOS
Expand the General option and then select Boot Sequence as shown below
Now Click on Add Boot Option under Boot List Option
A new window will pop up, under the Boot Option Name type in Windows Boot Manager and under File Name type in /EFI/BOOT/BOOTX64.EFI and then click on the small box which has three dots in it in front of the file name as shown below in the pic. Now click on OK, all entry will go away do not worry click on OK and then click Exit on the bottom right of the screen.
The system will restart now, it may take some time but it should load the Windows now. In case the issue still persists follow the next step.
Change the Boot Sequence
Sometimes changing the boot sequence in the right manner fixes the issue.
Start the system and immediately keep on tapping F2 to go to the BIOS.
Under the General select Boot Sequence and check the Boot List Option, is it set to Legacy or UEFI. If it is set to Legacy then set it to UEFI and hit Apply on the bottom right. Sometimes UEFI is greyed out. In that case, you have to make sure that under Advanced Boot Options “Enable Legacy Option ROMs” should be unchecked and Secure Boot should be enabled. You have to hit Apply after every change you make on the bottom right of the screen. See the pic below to understand it better.
After making the necessary changes hit Exit on the bottom right. The system will restart and it should load the Windows.
Sometimes doing vice versa also fixes the problem i.e.
Boot List Option- Legacy
Secure boot- Disabled or off and
Load Legacy Option ROMs – Checked
In case the issue still persists then jump to the next step.

Reset Windows 10 Using Advanced Boot Options
If somehow system files have gone corrupt then resetting the Windows will fix the issue. If you see the Advanced Options on the no boot screen then we can reset the Windows using Advanced options.
In case Advanced Options is not there then you have to let your system fail to start at least 2 or 3 times to trigger the Windows Recovery Environment.
Steps to go to Windows Recovery Environment:
- Press and Hold the power button to shut down your PC.
- Press the power button again to start your PC.
- On the first sign that Windows has started (for example, when you see a Dell logo) hold down the power button for few seconds to turn off your PC.
- Press the power button again to Start your PC.
- When Windows restarts, hold down the power button for few seconds to turn off your PC.
- Now press the power button again to start your PC.
- Doing this will allow your PC to restart in Windows Recovery Environment-WinRE. In case it does not take you to WinRE mode, try repeating the above process again till it boots to Windows Recovery Environment.
On the Choose an option screen, Click on Troubleshoot
Now click on Advanced options
On Troubleshoot screen, select Reset this PC or Factory Image Restore– Factory Image Restore option takes less time if this option is available then go for factory image restore.
On the Reset/ Factory Image Restore screen, select Keep my files/Remove Everything– It is recommended to select remove everything because if the system files are corrupt it may not work, please note that you will lose all the data on the system.
It will take some time to Reset/Factory Image Restore. RESET will take longer. Once it is done you have to set up the Windows 10 and start using your PC.
Reinstall Windows 10 Using USB Flash Drive
Many times, it is seen that the system does not go to the Advanced Options or Windows Recovery Environment in that case you have to reinstall the Windows 10 using the USB flash drive. In order to reinstall the OS, you need another working computer with internet access (to download windows 10 and create media on the flash drive) and at least 8GB of empty USB flash drive. Please note that reinstalling the Windows will remove/delete all the data on the system.
