HI Praveen. I'm Greg here to help.

I understand you cannot start Windows 11 due to Green Screen Stop code: UNMOUNTABLE BOOT VOLUME. I will give you the fixes for this crash, then all other ways to start WIndows when it won't start, and how to report it to Insider program when you get back into Windows.

First look over and try the fixes you can for Green Screen Stop code: UNMOUNTABLE BOOT VOLUME:

Use whichever method works in this link to get into Repair Mode so you can try the necessary repairs or do a Reset:

https://www.elevenforum.com/t/boot-to-advanced-...

Easiest is to force shutdown by holding in the power button. Do this twice. The third time you power on it should start into Repair Mode. Once in the Repair Mode try the numbered steps below.

It may be necessary to create bootable media on another PC to access Advanced Startup Options to try repairs, a Reset or do the Clean install. The bootable media has it's own set of files so that repairs or Reset might work better, doesn't require a password, and you'll have it to if necessary do the vastly superior Clean Install.

To create Windows 11 Installation Media on another PC install Media Creation Tool and follow the directions here under Create Installation Media, expand the link for "Before you get Started:" https://www.microsoft.com/en-US/software-downlo...

Insert media, boot it by powering up PC while pressing the BIOS Boot Menu Key given here: 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.

Choose the boot device as a UEFI device if offered, on second screen choose Repair Your Computer, then Advanced Troubleshoot Options, then:

1. Try a System Restore to a point before the problem started, working backward.
2. If that fails try Uninstall Updates button as far back as necessary to see if this was caused by an Update,
3. Open the Command Prompt to:

a) run System File Checker following Option Two here: https://www.elevenforum.com/t/use-system-file-c...

and DISM: https://winaero.com/how-to-repair-windows-11-wi...

b) run a full Disk Check: https://allthings.how/how-to-run-chkdsk-in-wind... which fixes glitches in the file system and can also signal a bad hard drive.

c) trigger Safe Mode with Networking (for internet) or Safe Mode following https://helpdeskgeek.com/windows-11/how-to-star... to roll back Updates & Drivers in Windows Update History, update your drivers from the PC/Motherboard manufacturer's website and try the other numbered repairs.

You can also create a new Local Admin account to replace yours: https://pureinfotech.com/create-local-administr...

d) From the Command Prompt enable the built-in hidden Admin account using Option 5 here: https://www.elevenforum.com/t/enable-or-disable..., sign in leaving password blank, create a new Local Admin account to sign into, set up, move your files over, when ready delete the old account to convert the new one to MS Account:

https://pureinfotech.com/create-local-account-w.... Then hide the built-in Admin again.

4. If those fail then go back to Troubleshoot Options to do a Reset. Choose to Save Nothing so it creates a new account (Rescue files if necessary first from Step 6 below) and Cloud Option to download latest fresh installation files instead of using corrupted onboard files.
5. If that fails choose Install Now, then Custom Install, then at the drive selection screen delete all partitions down to Unallocated Space to get it cleanest, click Next to let it create needed partitions and start install - this makes it foolproof. Everything needed to Clean Install is here:

https://www.windowscentral.com/how-do-clean-ins...

Create the Bootable media following the steps under Create Installation Media, clicking to read the link "Before you Start" at https://www.microsoft.com/en-in/software-downlo....

Make sure during the booted install to unplug all other drives, boot the media as a UEFI Device, choose Custom Install, delete all partitions down to Unallocated Space to get it cleanest, choose the Unallocated Space, click Next to auto-create and -format the needed partitions and begin install - this makes it foolproof.

After install expedite all Windows Updates including Optional until no more are offered. Then import any drivers from the PC maker's Support Downloads web page for your model that are newer, or branded instead of generic. The most basic thing we need to learn to maintain a PC is how to keep the latest manufacturer's drivers current. Windows drivers are rarely enough.

6. If you have files that aren't backed up you can use the same bootable media to try to rescue your files using these methods: http://answers.microsoft.com/en-us/windows/wiki...

Keep in mind that Insider builds are unstable by nature and for fixing bugs. It should not be on a PC you rely upon, only a test machine. If you want to leave Insider program and switch to a stable build see here:

https://www.howtogeek.com/758075/how-to-switch-...

If you will report Insider Build bugs using the Feedback Hub in Start Menu, you may be able to help improve this product/experience - especially if you are willing to share logs and other requested information. While they will probably not see this here in the forums, Microsoft developers DO read feedback from customers that comes in via the Feedback Hub, so that is a great way to share your thoughts on how to better serve you as a customer.

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
