    SonicBlue,

    The part of your earlier post that I did not understand was:

    Actually I prefer MBR for the dual boot situation, as where if you wish to access the other os is not possible with GPT.

    GB - obviously a typo.

    To be pedantic, it is 2 TiB (2.2 TB to one decimal place).

    Of course you can dual boot with other OSs in UEFI - it simply depends if other OS is UEFI/secureboot compatible.

    e.g. Many linux installs can handle uefi/secure boot.

    Yes that is true but can you access the other OS from within the other?

    Be careful if you use this utility. It only applies to a non system disk (ie. data only). If you convert for Windows disk, you won't be able to boot.

    If you wish. You can try this procedure for Windows system disk:

    UEFI only support GPT. In most cases, you will be fine with either MBR or GPT. It is only when you need to have a partition bigger than 2TB, that you need to use GPT, or convert MBR to GPT.

    I use both MBR and GPT on my main rig. Windows 10 10586 on GPT as my day to day OS and Windows 10 Insider Preview on MBR. I prefer this setup because the 2 don't see each other whatever mess I make with the Preview OS. I don't get boot issues at all. Totally independent of each other. But I guess it depends on motherboard. I have an ASRock Z97 Extreme6. The GPT disk is a 2100MBps Samsung SM951 M.2 SSD while the MBR is just a regular Samsung Evo SSD.

    This is not a dual boot setup. I select a boot device on start up.

    Hi there

    Secure boot is a "Go and do something that rhymes with Duck" word - especially if you want to test / run alternate OS'es / boot from USB sticks etc.

    UEFI enabled boot does not need to have secure boot - but it DOES require GPT so that's a good reason to start with. Most people though usually have a small SSD (up to say 256GB) and reserve that for OS and applications so it really doesn't matter if it's MBR or GPT.

    For HDD's > 2 TB you will have to have GPT in any case. The only reason I still bother about MBR is that if you have something like a bootable rescue USB and several computers including some older ones having a BIOS MBR boot makes the device more flexible.

    IMO though for most people stick these days with GPT - but forget SECURE BOOT unless you are forced to use it -- it's a real pain when you need to backup / restore a system with external media / boot devices.

    BTW Rootkit viruses (as are most viruses in general) so "Last Century" -- Criminals get much more money by simple SCAMS these days that just rely on Lack of Brain Power of the average user -- such as "Fake websites", emails with dubious attachments, emails from what looks like official bodies requesting money / passwords etc.

    I've used some sites (not allowed to be mentioned here - but Felines and ships with black flags and skull and X-bones might be mentioned !!!) to get TV / movies that are "Geo-Blocked" and aren't likely to be shown where I live --Happy to PAY for content but if the Movie people won't see sense then the alternative is the only option - and THEY lose money !!! -- and can say never got anything nasty from those places.

    By all means install / use AV software to protect your system --but threats from "Technology" aren't anything like as dangerous as those hideous scams that people fall into every day.

    Remember --The price of Education is expensive -- but the price of Ignorance is Astronomical " -- anon --don't know who quoted that but it's so very true.

    Cheers
