Hi,You already have four partitions
10 can't install another one just for the 10 installer 450mb system recovery so the install will likely fail with disk issues.

Is MBR's limit 4 partitions or 4 primary partitions?

Best to use another ssd.

Why? What's wrong with the SSD?

Mini tool can make it gpt.
How to Convert MBR to GPT without Data Loss in Windows 7/8/10

Should I format it as GPT or leave it unallocated?

Hi,
Yes read the tutorial too though by @Brink might say something important you might not want to skip or miss

Pretty sure it has to be a gpt disk

HI,
Been through that one
Op obviously wants the perk in performance of the ssd on both os's

Since you will be dual booting with Windows 7, it would probably be best and easiest to just select a separate unallocated disk to install Windows 10 on while having the Windows 7 disk connected.

If I leave the space unallocated, will the W10 installer make the SSD a GPT disk? Is it a problem if you have both MBR and GPT disks?

Hi,
Installer will not change the disk format from mbr to gpt.

The tutorial says to:

5. In the disk (ex: Disk 1) that you want to convert to a GPT disk, right click on each partition and volume on the disk and click on Delete Volume until the whole disk is unallocated space. (See screenshot above)

6. Right click on the disk (ex: Disk 1) that you want to convert to a GPT disk, and click on Convert to GPT Disk. (See screenshot below)

Is that safe to do? I read "right click on each partition and volume on the disk and click on Delete Volume" and my heart skipped a beat! I'm not criticizing. I'm just asking.

Hi,
I haven't done it personally win-7 as far as I know isn't compatible with gpt unless some kung fu is done before the install.

As a storage devise gpt is nothing for 7 deal with.

How was the mini tool instructions ?

Do you have a system image of 7 disk now ?
