I have only one hard disk running Windows 7, and it is an MBR disk. I want to install Windows 10 on this disk, but the computer pops up a warning showing that Windows cannot be installed to this disk. On UEFI systems, Windows can only be installed to GPT disks. Therefore, how can I convert it to GPT? Can anyone help me?

According to your description that you say how can I change an MBR disk installing Windows 7 to GPT, I can learn that you need to convert your disk running Windows 7 from MBR to GPT, and then you can install Windows 10, which allows the UEFI partition to live anywhere on the disk.
So how can you achieve the conversion of the disk running Windows 7 from MBR to GPT? Here are some ways for you to follow.
The first way is to use a third-party tool: EaseUS Partition Master. It can help users convert the disk from MBR to GPT. In addition to that, it can also finish the conversion of the disk from GPT to MBR. Moreover, it is perfect software in a simple and operable way. Compared with other methods, users do not need to delete all the files and partitions on the disk, especially for your disk running Windows 7; it is more suitable and easier. You can try this software.
Of course, if you are still afraid of losing some important data on the disk, it is recommended that you need to make a backup of your important files. Here are some steps for you as follows:
Step 1. Download EaseUS Partition Master on your PC and launch it.
Step 2. Go to Disk Converter, select Convert MBR to GPT, and click Next to continue.
Step 3. Choose the hard disk that you tend to convert to GPT, and click Convert to start the conversion.
Besides the above function, the EaseUS Partition Master can also help users achieve some other functions, such as:
In a word, it is a perfect choice for users to convert the hard disk running an operating system from MBR to GPT, especially for those novice users. You can choose this software to have a try.
The second method is to use Command Prompt to fix your problem. Compared with the first method, this way is more difficult and unsuitable for inexperienced users. At the same time, you must make a backup of all your important data on the disk in advance because using Command Prompt will delete all your files and partitions on this disk. Therefore, do not forget that.
And here are some detailed steps for you:
Step 1. Type CMD in the Search box. Select Command Prompt, and then you should choose "Run as administrator." If CMD is unavailable, you can use PowerShell to replace it.
Step 2. Open Command Prompt, type DiskPart, and then you need to press Enter.
Step 3. Type list disk and press Enter. (You have to note down the number of the disk you want to convert)
Step 4. Type select disk #. (Replace the # with the number of your disk)
Step 5. Type clean and press Enter. This command will delete all the files and partitions from your disk.
Step 6. Type convert gpt and press Enter.
After the above steps, it is believed that you can achieve the conversion of your disk from MBR to GPT. Comparing the above two methods, it is suggested that you can choose the first method as the second one is more difficult and unsuitable for computer beginners. Now you can try to fix your issue.
