I have tried casper-rw and ext2.

The following questions are where I'm at:

  1. Can I use a Linux boot stick to check the desktop windows partition for viruses and/or rootkits? If not, why?

  2. How is a casper-rw file different from a casper-rw partition (or is it the same thing?)

  3. What are limitations of a persistence Linux boot stick that I might (and most probably are) not be aware of?

    kali? Don't think the kali distro is a good place to start for the linux novice... Linux boot will allow you to do most anything needed on your Windows partitions. Commented Jan 28, 2019 at 18:28

    @jc__ I agree with Kali Linux not being the best option to get to know the Linux universe. Then again I usually drive on curiosity as a motivator - so sometimes I don't go the obvious/convenient way. I'll keep it in mind though. Commented Jan 29, 2019 at 12:19

    @K7AAY 1. Mostly virus /rootkit scans or data rescue 2. understood 3. That's what I meant - thanks for clarifying. Will check out the links you provided >> Commented Jan 29, 2019 at 13:36

    @GAD3R thanks! I guess it's not hard to see I'm new to this. Is it "acceptable" if I just edit it down to one question in this case? Obviously I don't want to cross any rules. Commented Jan 29, 2019 at 17:23

1: Can I use a Linux boot stick to check the desktop windows partition for viruses and/or rootkits? Yes, you can. Examples include Bitdefender, AntiVirus Live, and numerous others.

2: How is a casper-rw file different from a casper-rw partition? Same thing, a casper-rw file is treated as if it is a writable partition, and is used to store your changes and additions to the filesystem.

3: What are limitations of a Linux boot stick with persistence that I might (and most probably are) not be aware of? They boot slower, and most LiveUSB creation tools (one example), if they offer persistence, are limited to a maximum of 4095 KB in persistent size. See https://www.pendrivelinux.com/what-is-persistent-linux for an overview and, for an explanation of how to exceed that normal limit, see https://www.pendrivelinux.com/create-a-larger-than-4gb-casper-partition .
