To expand the VHDX file via Hyper-V, follow these steps:

1. Ensure there are no Checkpoints

Before proceeding, make sure your virtual machine has no checkpoints.

2. Navigate to Settings

Go to Virtual Machine > Settings... > SCSI Controller > Hard Drive.

3. Edit the Virtual Hard Disk

Press Edit under Media > Virtual hard disk.

To expand the /dev/sda size, follow these steps:

1. Install Required Package

2. Find the Virtual Disk Name

Use fdisk to find the name of the virtual disk.

In the output, you should find the device table:

Device      Start      End  Sectors  Size Type
