Hello @Aritra Basu

The blue screen error message indicates that the underlying OS for the VM is not booting properly.

To fix it,

please go to the Azure Portal, select the affected VM, then navigate to Help > Redeploy + Reapply. First, click Re-apply on the VM, and then Redeploy the VM. This process often resolves OS and host issues that can prevent the VM from booting.

Faster way;

If you have a backup of your VM from before the blue screen error, you can restore the VM to that previous state using the backup.

Additionally, please confirm:-

What OS is running on the VM?

Are you able to connect the server/website running inside the VM?

BSOD error: NTFS_FILE_SYSTEM on Windows Server 2016. This usually indicates OS disk corruption.

Steps to fix:

Stop the VM from Azure Portal.

Detach the OS disk:

VM → Disks → Select OS disk → Detach.

Attach the OS disk to a healthy Windows VM as a data disk.

On the healthy VM, open Command Prompt as Administrator and run:

chkdsk X: /f /r

(Replace X with the drive letter of the attached disk.)

After it completes, run:

sfc /scannow /offbootdir=X:\ /offwindir=X:\Windows

Detach the disk from the healthy VM.

Reattach it back to the original VM as OS disk.

Start the VM.

In most cases, chkdsk fixes the NTFS_FILE_SYSTEM blue screen.
