BIOS not appering after installing UBUNTU

Hi Paresh. I'm Greg, 10 years awarded Windows MVP, specializing in Installation, Performance, Troubleshooting and Activation, here to help you.

I will give you all possible steps to troubleshoot Windows installation failure that I've given to thousands of others in this situation and which work in about 90% of cases. If not we'll go from there:

Follow the gold standard Clean Install steps in this tutorial which compiles the best possible install that will stay that way as long as you stick with the tools and methods given: http://answers.microsoft.com/en-us/windows/wiki...

I am the author of this Clean Install tutorial which has been used by millions of consumers in Windows 7 and 10, and helped popularize Clean Installs with consumers over the past decade. In addition I've helped troubleshoot tens of thousands of cases of install failure and never had one fail to get installed if there is close cooperation. So let's get started:

Make sure all other drives and peripherals are unplugged. Update the BIOS or UEFI firmware to latest, or reset to Defaults, making sure (if you have it) UEFI is enabled, CSM or Legacy BIOS disabled, Windows Boot Manager set first to boot, if necessary disable Secure and Fast Boot until after install, set SATA controller to AHCI, Save changes and Exit. Access BIOS/UEFI Setup as shown here: https://www.mydigitallife.net/comprehensive-lis... https://www.groovypost.com/howto/reset-pc-bios-...

Create the latest Windows 10 Installation Media by installing Media Creation Tool and following the directions here: http://windows.microsoft.com/en-us/windows-10/m....

If you're using another PC to do this uncheck the box for Recommended Settings to choose the exact version and bit rate for the target PC only. Insert media, boot it by powering up PC while pressing the BIOS Boot Menu Key: https://www.sysnative.com/forums/hardware-tutor...

If the media won't boot you may need to enter BIOS/UEFI Setup (pressing key given in chart in link above) to turn off Fast Boot or Fast Startup first. If you can start Windows enter UEFI firmware here: http://www.isunshare.com/windows-password/four-...

The media may also be bad, so confirm it boots and queues up per these steps in another PC, or else recreate it. You can also try a DVD, or the alternate download site from MS TechBench here: https://tb.rg-adguard.net/public.php. Burn to DVD using WIndows Image Burner or create bootable flash using one of the options here: https://www.tenforums.com/tutorials/2376-create...

Choose the boot device as a UEFI device if offered, on first screen press Shift + F10 to open a Command Prompt, type the following commands, each followed by Enter key:

DISKPART

LIST DISK

SEL DIS # (replace # with the disk # of the Windows disk from list in previous command)

CLEAN EXIT

Close Command Box, on second screen choose Install Now, then Custom Install, then at the drive selection screen choose Unallocated Space, click Next to let it create needed partitions and start install - this makes it foolproof.

Make sure to follow the setup steps in the first link tutorial to complete your install. Drivers are important enough that those steps are printed in red. If installation stalls or won't complete, try disconnecting from the internet. You will get and keep the best possible install to the exact extent you stick with the steps, tools and methods in the first linked tutorial. It's a better install than any amount of money could buy and a great learning experience that will make you the master of your PC.

Failures and errors during the Setup phase can often be overcome by disconnecting from the internet, e.g. unplug router.

If all else fails you can move the hard drive to another PC to do the install with it plugged in alone. Windows 10 is remarkably adaptive to new hardware without needing adaptive restore. If it will start it will swap out all drivers requiring several restarts. You can also try applying a same-version System Image to the intact SSD/hard drive.

Please report back the results of each step so I know what else to suggest.

Sir,

I have followed the above steps in para 1, Still unable to get bios screen. The only thing i get is the ubuntu grub menu. All problems will be solved if only i get an acess to BIOS. please help for the same. Thanks

If you cannot trigger BIOS from it's hotkey given on first screen or here:
http://www.mydigitallife.info/comprehensive-lis...

then reset the CMOS which normally will free it up to be accessed:
https://www.maketecheasier.com/how-to-reset-cmo...

Then see if you can trigger media via Fkey given earlier.

If that doesn't do it then unplug the drive that GRUB has corrupted. If you can then get into BIOS to change boot order to the boot media first, plug drive back in to see if you can then start into media to wipe the drive per my earliier steps.

If not then slave the drive to another PC to wipe it with Clean Command, move it back to continue with install troubleshooting steps.

Greg my brother. I have successfully got the bios screen with your help. I have set the bios to start from the usb. But it just brings up the grub command line screen. Please suggest

Paresh -

Isn't GRUB on the hard drive or SSD only? That means that your media is not interrupting the hard drive starting. It must not be correctly created. You can test this on another PC to see if it will interrupt the normal startup and load, queue up to the Install Windows > Custom Install and show the drives.

If not then it is not good media. Go back to the steps I wrote for Troubleshooting install to create the media properly on another PC. Then continue with those steps to clean the drive and reinstall Windows.

There are also these methods to remove GRUB from hard drive when it is blocking boot:

If nothing else works then slave the drive to another PC to wipe it with Diskpart Clean Command.

I will definitely try that and let you know the result. Forgot to thank you for helping me get the bios. Thank you soo much❤️

I am always happy to help Paresh. Keep me posted on your progress as I will be here to help until the case is resolved.

Back tomorrow late morning, California time.
