Hi RICHSVEN,

Since you have mentioned that system is not booting up normally and stuck at Dell logo, you can change the settings in BIOS page. Please follow the steps below.

Tap ‘F2’ as soon as the computer starts to enter the BIOS

Please ensure that you are able to see the headings ‘Main’, ‘Advanced’, ‘Wireless’, ‘Security’, ‘Boot’ and ‘Exit’ on the screen

Use the right-arrow key to navigate to ‘BOOT’ menu Change Secure Boot to disabled, and Change Boot List option to Legacy. You can go to advanced options Ensure SATA mode is set to Intel Smart Response Technology click on Exit save changes and Reset

Once you restart the computer you should get the Intel Option, Rom option will come up in the screen. At that point Press Ctrl + I at this window and Press R to disable acceleration. Press 6 to Exit

Tap ‘F2’ as soon as the computer starts to enter the BIOS. Go to Boot option and Change the Boot List option to UEFI and Change Secure Boot to Enabled. Click on Exit save changes and reset. Restart the computer and system should boot up normally.

You can go ahead and update the BIOS and the other drivers which is available for your laptop. Please use the link below to update the drivers.

In this link please punch in the system service tag or express service code and choose the appropriate operating system (windows 8 64 bit) and download the drivers. You can also change the Windows Update settings. Please follow the steps below.

Press the Windows key and R >Type in control (You should get the control panel) >Choose System and Security > Windows Update > Change Settings > check for updates but let me choose whether to download and install them > under the recommended updated > check the box (give me recommended updates the same way I receive important updates) and click on ok.

I hope you find this useful.

Hi Senthil, thank you for your answer, I called the technical support service today and the problem was on the Bios setting, we changed the SATA mode from Smart Response Technology to AHCI after loading the default/optimal setting. The root of the problem was that the Windows 8 OS is installed on the SSD drive and the system wasn't checking this drive when booting. The laptop is working fine now.

Hi all,

I had the same problem with my new XPS14 and I called the italian Dell support but they were't able to give me an explanation and even to solve the problem.

They suggested to me of buying Window8 and transfering it into an usb key in order to install again the operative system.

But I didn't trust in their suggestions...furtanately!!! And then I found this post and I followed the technical support service suggestion qnd it worked!!!

THANKS A LOT!!!!

Cheers

Hi Marianna_Italy,

You can refer to the above post and follow the steps to resolve this issue. In case after trying the above steps and it’s not working, please reply with the exact error message.

Hi Senthil

I had the same problem with my new XPS L421x and tried the steps as outlined by you. Everything worked except the secure boot option, it does not allow me enable the secure boot after the entire process in the BIOS. What do u I do from here.

The PC works perfectly but I'm worried about the secure boot being disabled.

Please advise asap.

Hi Thefuhrer,

Please let us know when you are trying to enable the secure boot; do you get any error message? In case there is an error message, please send us the error message preferably with screenshot.

Hi visaster ,

Kindly run the Dell Diagnostics and revert if any there are any errors.

Kindly find the steps below to perform the H/W diagnostics.

Turn the computer off >restart the computer

At the Dell logo screen, start tapping the F12 key a few times until you see the ‘One Time Boot Menu’ appear.

At the one time boot menu, press the down arrow key to highlight ‘Diagnostic’, and then press Enter to begin the PSA diagnostics.
If the test fails, please make a note of any error codes listed. You can also refer to the link below.

Any further to this issue? My Secure Boot is also Disabled and can't be Enabled also...

Thanks 

After power on, press F2 before the logo appears.

This will take you to the BIOS.

Use the arrow keys to get to the BOOT tab

Change SATA mode from Smart Response Technology to AHCI

Press F10  to save and exit and voila!

Good luck

Hi RICHSVEN, You comment just saved my loads. I think everyone with this problem should simply follow this solution.

Thanks mate.

So what happens when you turn it on?

Hello, I am having the same problem, Except I am not able to go to bios or diagnostic screen, pressing f12 and f2 makes no difference
