Trying to install windows 10 on an hdd, I’ve formatted the partition I’ll download windows on but I get a message saying “Windows cannot be installed on this disk. The selected disk has an MBR partition table. On EFI systems, windows can only be installed to GPT disks.”

Then you need to start over, and reformat the drive during the install.

I read it but does that mean that I'll have to format and delete or partitions then divide them again? and is there a way to backup before doing that? I can afford to lose the data but I'd rather not.
 


You're installing this on a drive with data already on it?
Why?

That NEEDS to be backed up somewhere else.

You can't partition some of it MBR and some of it GPT.
Doesn't work that way.
 


I'm upgrading my pc, I replaced everything except the GPU and HDD. From the research I did I knew I had to reinstall windows, I've installed windows before on the same hdd without formatting all of it so I thought I could do that again. I don't need the data on the drive plus I dont have anything big enough to back it up it'll be too much of a hassle to back it up, so with that decision do I just format all partitions and delete them then redivide them?
 
Yes you will need to delete the partitions, no need to create them yourself. During the windows installation, let the installer specify and create the partitions for win10. There are many ways to perform a backup, something everyone should be doing anyway. Windows includes backup software depending on what version you are currently running.

Now the whole drive is unallocated space and I can press next onto installation, I'm just afraid that it'll be setup with only 1 partition which has windows on it. I can create new partitions and still press next on installation, should i create the partitions or will the setup give me atleast two partitions?
 


Windows setup will create the needed partitions.
 


By default, te OS install will use the whole drive space, creating what it needs.

If you really want, you can use only some of it for the OS.
What size is this drive, and why multiple partitions?
 


I installed windows with the partitions I wanted, I prefer having 3 partitions, 1 for windows and 2 to be devided between games and documents, movies, etc. It's just a preference I guess.
Thank you both you've been very helpful with instant replies.
