How to create Virtual Machine in Azure Free Services without cost

Question

Azure says here that

750 Hours of B1S VM and 64 GB X 2 Managed Disks, 2 P6 SDDs

and some others are free each month for 12 months.

On VM create in Azure Portal, There are Basics, Disks and other tabs, In Basics, I could able to select Image Size to B1S VM but in Disks tab, there is no option to select Managed Disk of 64GB of P6 SDDs.

There are only three options i.e Premium SSD, Standard SSD, Standard HDD. Whatever I select and proceed further, VM takes default of 128 GB C Drive and 4 GB of Temp Drive and starts billing.

Where can I select that free 64 GB X 2 Managed Disks, 2 P6 SDDs.?

Answer 1

I don't think you can change disk os disk size at all (only increase it), but there are Windows images called smalldisk; those have 30gb disk. You can use those, they should work just fine.
