Started work on EasyOS graphical installer
Still a lot to do, but here are some snapshots. The startup window:

Install to entire drive help:

For frugal install, the Installer cannot do everything. Just like the mainstream installers, such as Calamares, some things have to be done in a running MS Windows. Especially these days, as it seems most Windows installations in modern computers have encrypted drives, using BitLocker.
So, I will need to revise and improve the instructions for
defragmenting and shrinking the main C: partition, and turn off
Fast Startup. After that, there will be free space in the drive,
and gParted can be used to make a ext4 partition, and maybe
another FAT partition. Though, Easy Installer could also be coded
to do this.
