Windows 10: Blank screen after logo at startup

Hi,

I have a Lenovo Flex 2 15 Model 20405. Yesterday, I decided to reformat my laptop to Windows 10. On the near end of the installation, it prompted me to restart the computer (it restarted itself after 10 seconds), but after the Lenovo splash screen, I get a blank black screen.

I recently came from an Ubuntu OS, not sure if it changed the BIOS settings.

I have tried the following instructions bellow. I was successful in rebuilding the BCD, but when I restarted my computer I am still stuck at blank black screen.

Code: bcdedit /export C:\BCD_Backup c: cd boot attrib bcd -s -h -r ren c:\boot\bcd bcd.old bootrec /RebuildBcd bootrec /fixmbr bootrec /fixboot Remove the Rescue CD and try rebooting now.[/quote]
Other things I have done so far:

• I've checked the hard drive from BIOS, it's reading it properly.
• I've tried resetting BIOS to defaults.
• I've run chkdsk.
• I changed the boot order priority (HDD first), I tried other boot order as well.
• I switched between UEFI and Legacy Support
• Pressed F8 (or FN + F8 ) to bring up Safe Mode, but nothing showed up.
• I can boot from Windows Installation disk. I tried all troubleshooting options like Refresh and Reset, but I get the message "This option is not available in the OS you selected" - must be because Windows 10 did not finish up during installation so there's nothing to refresh or reset.
• I have tried installing other Windows OS like Windows 7 and 8 but still getting the same black blank screen.

The laptop has a built-in battery which is why I couldn't remove it to reset CMOS settings.

I have been working on this for 3 days now, any help would be greatly appreciated.

Thank you

:)

 

Blank black screen when I turn the computer on

[*]Did you tried force shutdown? I forced shutdown
[*]Are you able to see Manufacturer logo during Startup?
At startup the manufacturer's logo appears along with "F1 Setup" and "F2 Boot Options"
[*]After Windows logo, will it goes to black screen? After the blue Window's logo, the screen goes blank/black
[*]Did you see any error message along with Black Screen?
There is no error message.
[*]Have made any changes prior to the issue? I made no changes prior to the issue other than clicking on the link to download Windows 10.


I don't know what a recovery drive is and am pretty sure I don't have one.

Thank you.
Andrea

 

Blank screen on 10 install

Have installed windows 10 on my laptop with no problems but on trying to install windows 10 on the wife's laptop, both running windows 7, the screen has gone blank (yes, it still has power) and does not move on. Have powered off and rebooted and Dell's
front screen appears for a few seconds then a blue screen with the new Windows logo comes up with the working circle running but after about 30 secs screen goes blank although still illuminated. A message came up at one point saying error occurred at startup,
restarting, but still stuck on blank screen after being left overnight. Seems to be stuck in a reboot loop

 

Hi carlofontanos. Welcome to the TenForums @carlofontanos

I would first recommend you follow this tutorial to clean install. Note the two BIOS settings you have to adjust, secure boot and Fast Boot.

Clean Install Windows 10

I would also suggest so that there is nothing to conflict or interfere you do this.

Boot the computer from Windows 10 installation USB flash drive or DVD. When the first screen comes up press shift + F10. In the command window that opens run the following commands. This will erase the entire hard drive!

diskpart
List disk
select disk 0 (In this example disk 0 is where you want to install windows, adjust to your needs.)
clean
Convert gpt (if you plan to boot UEFI)
exit
exit

Of course only run the above if you no longer want any of the info on this drive. Let Windows assign partitions needed.

To get the process kicked off to get to safe mode, future reference, hold shift down and click restart. You can also power up Windows and when you see spinning dots hold power key until it shuts off. Repeat again. On third try it should boot to advance startup menu. Link to tutorial
