How to break Microsoft's monopoly

I believe that desktop/laptop computer OEM's should be required to ship their machines configured in one of the following ways:

A) Windows is installed with Linux in a dual-boot configuration

B) When powered on for the first time, the user is offered a choice: - install only one of them - install both of them

C) Regardless of the above, have the 'Recovery Partition' contain the tools necessary to install either, with the option to switch the OS at some time in the future.

It's a dream I have.

Cool feature of btrfs file system

Fun fact:

You can convert an existing EXT2/3/4 file system to 'btrfs' in-place.

(Of course you still want to make a backup...)

No.

WTF is that, and why should I care?

Yes - hardware RAID controller

Yes - Windows - RAID1

Yes - Windows - RAID5

Yes - Intel 'Soft RAID' (some consumer motherboards)

Yes - Linux - kernel RAID (mdadm) + FS directly on RAID device (e.g. /dev/md0)

Yes - Linux - kernel RAID (mdadm) + LVM + FS on LV (logical volume)

Yes - btrfs - RAID1

Yes - zfs - RAID1, RAIDZ1 (1 parity disk), RAIDZ2 (2 parity disks)

There are two kinds of computer users. Those who have lost data, and those who are about to.

Do you make backups?

Yes - data only - paid cloud (Amazon S3, Backblaze, etc.)

Yes - data only - local removable media / second HDD/SSD

Yes - data only - local NAS

Yes - full system - file-by-file

Always thought it would be fun to have a worm that modifies the boot drive to add a small partition, drops a bare-bones Linux install that then gradually migrates their Windows install to Linux with a Windows UI.
