What are you hoping would be revealed? Why don't you just explain what you mean?

I already know the basics of UEFI and GPT. And I know what a boot manager is. And I'm quite familiar with multibooting using a BIOS and MBR partitioning scheme.

I just don't have a clue why you posted that image or what relevance it had to the purported difficulties in multibooting using UEFI.

you said "What's the difficulty in multi-booting using a UEFI-based motherboard? (I haven't used UEFI myself.)"


when you set a machine up using uefi on win 10 you will see it creates 4 partitions instead of the normal 2


why not locate a UEFI board and try multiboot , you will find that if using uefi to advantage win 10 , it will severely hamper multibooting into other os


MBR is a max of 4 partitions , gpt is the way to go , check that your other os,s like gpt

How does that cause a problem with multibooting? :huh:

And, from the image you posted, I can only see three entries representing two devices: a Western Digital hard drive and a Sandisk SSD. How does the screenshot demonstrate a problem with multibooting with UEFI? :huh:

Hey! Why not give me a board to practice on?

I still don't understand what it is about UEFI that "hampers" multibooting. What do you mean by "hampers"? You mean it's difficult to set up, but possible? If it's possible, what's so hard about doing it? How does one overcome these difficulties? :huh:

You may only be able to have four physical partitions with MBR, but you can replace one physical partition with an extended partition. Inside an extended partition, you can create a (theoretically unlimited?) number of logical partitions.

To the OS, primary and logical partitions behave identically.

ok heres instructions , so easy for the average man on the street http://www.zdnet.com/article/hands-on-linux-uefi-multi-boot-my-way/


so to answer the OP , its not Microsoft that are "writing" to the bios , its newer machines with uefi that are causing problems due to lack of detailed instructions

Le_Kirk

To summarise: -
It's not MS that is preventing dual booting.
It is newer machines with UEFI that is causing the issue BUT: -
it is only because of lack of detailed instructions preventing it being done.
I followed the link in post #16 but it is for Linux and I was discussing W10/W7 dual boot.
I don't actually want to do it (yet) was just advising someone that a possible way out of some old software not working under W10 can be overcome by dual booting W10/W7.

I was not suggesting they are, what I wrote was I had read it on a couple of recent threads

That's OK, I'm just pointing out that what you read was nonsense.
There's no problem at all with multiboot including Windows 10 with UEFI BIOS or old fahioned BIOS. Some people seem to just like to make things up when they don't know how to work computers it seems!
