Did you 2 just have a shared "jerryleecooper" moment? 

[What programming language to learn?]

there are Linux c# and python compilers...

That's like saying anal sex is better because it works with all genders.

[Booting with no Keyboard...]

I've noticed the BIOS to print such a redundant message, but an operating system typically doesn't.

Plug in a keyboard, disable the check for the keyboard... I hope you installed a USB mind reader though.

[Hard Drive Problems]

BSD slicing just seem unnecessary some how, i don't get how slicing a partition helps any thing tbh.

While it may seem, "unnecessary" to you. .  it's necessary for BSD users.

BSD partition labels predate the IBM PC's MBR partitions.

One really cool benefit is the ability to create up to 16 partitions per drive, each of which can be mounted with separate options:

/dev/wd0a / ffs rw 1 1
/dev/wd0g /home ffs rw,nodev,nosuid 1 2
/dev/wd0d /tmp ffs rw,nodev,nosuid 1 2
/dev/wd0f /usr ffs rw,nodev 1 2
/dev/wd0e /var ffs rw,nodev,nosuid 1 2

In this case, I can prevent devices/setuid root files from being used inside various mount points.

I typically backup a few things from /etc and /var each month then start fresh, preserving only my home partition. .  :)

Oh, And hello everyone, this happens to be my first post.  8-)
