Count me in as a linux user !
If anyone needs help understanding some basic functionality of linux,bash or C language,needs a simple script, work with disk partitions,setup a grub2 bootloader for booting multiple systems, install windows,linux or a macos hackintosh,setup virtual machines I can try to help.
My experience is that generally linux is the best operating system for efficiency,resource usage, customizability,availability of a huge amount of free software and tools both graphical and command line, coding flexibility and last but not least the linux itself is open source and free to install;i found the LUBUNTU linux the best tradeoff of a mainstream distribution (ubuntu is typically the most widely supported distribution) with smallest footprint for good performance and at the same time quite fully featured.
I attached some notes and explanations in the file linux.txt
and 2 more files in the following post
