If you really would like to try Vector linux then the first step is understanding your hardware. if you have a fairly new computer it likely employs uefi. or secure boot options. If you installed linux mint to the hard disk then the procedure may be similar. If you dual booted with windows then the procedure may be differant again. perhaps you have a second hd or need to disable secure boot. If the computer is five or six years old then you have a better chance of installing with a few mouse clicks. even ubuntu is not immune to the kleenex boxs that look so great on the table but are full of disposable fluff. Perhaps you are well versed and have discussed this in other threads. just a thought in passing. Best of luck
