    Hi @jihad majed

    Typically occurs due to the following reasons:

    1. Disk Size Limitations:

    a) For Generation 1 VMs, the maximum size allowed for the OS disk is 2 TB1.

    b) For Generation 2 VMs, the maximum size allowed for the OS disk is 4 TB2.

    1. Disk Type:

    Ensure that the disk is a fixed-size VHD. Azure does not support dynamically expanding disks for OS disks1. - Most Common error.

    1. Disk Preparation:

    If your OS disk exceeds these limits, you may need to resize it. This can be done by shrinking the volume within the operating system and then using tools like Hyper-V Manager or PowerShell to resize the VHD file3.

    1. VM Generation:

    Verify that the VM generation is compatible with Azure. Generation 1 VMs are more commonly supported, but Generation 2 VMs are also supported with certain limitations2.
