I want to install (not a live ISO) Slackware 14.1 onto a flash drive so that I can boot it via plugin to a port. Can I install it from the ISO I have on DVD?

I got involved with a pre-installed (never again) Windos 8.1 laptop and think I have a death grip on it as I hang from the cliff. Now I have real problems!
I have taken off the fast boot capability in case I need to re-install the Windos. What can of worms have I opened?

My understanding is that to install 14.1 I need to disable secure boot. Now M$ says it has software to protect from "bootkits" infecting Linux OSes (thus addressing concern of keefaz) but don't know if that will work with Slacware to provide the necessary certificate for the UEFI.
I read that the instructions say just turn off 'secure boot' but that leaves the system exploitable. What is the scam on this or is there any solution?

Thirdly, will Slackware protect against "rootkits" post UEFI booting in phase 2 of the booting. Or is it necessary to run rootkit after each bootup?

You need to disable secure boot, Slackware has no bootloader signed by Microsoft (AFAIK )

uefi rootkit detection feature cracked in 2013:

Regarding certificates. My take on this M$ software (found in M$'s "Securing Windows 8 Boot Process")is that it creates the certificate by examining the Linux system and puts the certificate of authenticity where only the UEFI can access it during secure booting and thus prevents installation of bootkits, i.e. thus "secure boot" can remain enabled. I understand that Ubuntu oriented Linuxes are leaving secure boot enabled. This may be a consequence of being Linux Standardization LOL. Please correct me if I got it wrong cuz it was a very quick scan of M$ help article.

Thanks 4 the update on cracking of rootkit. Disappointing.
