I recently tried to install the windows 10 preview on my computer. I needed to dual boot, so I made a bootable usb with the .iso on it and restarted to boot from the USB stick. That's all fine, but when I got to the stage where you select the partition to install 10 on, it said something along the lines of 'you cannot install windows on a mbr drive. Convert to gpt'. How do I do that? And since I only and running one hard drive, will it erase all my data from other partitions or will it still be there afterwards? As well, for anyone out there who is using or has used windows 10, is it any good?

So it will totally format the drive?
 
Yep I got the same error I had a small 500 gb drive laying around so I installed 10 on it so if you have a drive laying around that would be the way to go I wasn't going to format my entire drive to give win 10 a test drive.

When I tried to install it it told me I couldn't install it on a GPT partitioned drive. Is this because you can't dual boot it, it wants the entire drive to itself?

GPT is a newer partition standard and MBR is the older one. GPT will require you to format your whole driver its not about windows wanting the whole drive it's just the way Partition standards work

The OP said he couldn't install because his drive was MBR. What needs to happen, does Windows have to format the drive? My GPT drive wouldn't work, and his MBR doesn't. What's the solution? Not to hijack this thread...

During the windows install
Delete the Drive
Format drive or new
Then use that drive
Or
Use these commands in the Command prompt also in the install disk
diskpart
list disk
select disk <disk number>
clean
convert gpt
exit

I also would like to know if it will blank the entire drive, or just the partition I want to use for Win10. I want to keep my Win7 on the main partition, but want to try Win10 on my blank partition.

I got it to install on a separate partition just fine, and I'm dual booting windows 7 and 10. It will only wipe the partition you want to install it on, unless you tell it otherwise in the installer.

Yes it will completely reformat the drive, destroying all data.

I know I'm late to this party but I just got though the original OP's very issue. Easiest solution which DOES NOT DESTROY DATA, is to create a bootable USB drive using your WIN 10 ISO image and RUFUS bootable USB utility....http://rufus.akeo.ie/ When creating the image on the thumb drive, under "Partition Scheme and target system type" dropdown, select "GPT partition scheme for UEFI computer". Keep the file system as FAT32 and create the bootable ISO image...It wiil take several minutes, so go grab a cup of joe. When it's done, make sure you adjust your BIOS to boot from USB drive first...It will go through the install and allow you to install WIN 10 on your GPT Partition like normal, without destroying data. Hope this helps someone.
