Here's how to Fix The selected disk has an MBR partition table.

Here are some possible solutions to the error "The selected disk has an MBR partition table" when installing Windows:

1. **Make sure that the BIOS is set to boot from the USB drive.** To do this, you will need to access the BIOS setup. The BIOS setup key is different for different computer models. You can find the BIOS setup key in your computer's documentation.

Once you have accessed the BIOS setup, you will need to find the boot order option. The boot order option is usually located in the Advanced or Boot tab. Change the boot order so that the USB drive is the first device in the list. Save the changes and exit the BIOS setup.

2. **Convert the disk to GPT.** To do this, you will need to use the Diskpart command-line tool. To open Diskpart, press `Windows`+`R` and type `diskpart`.

In Diskpart, type the following commands:

```
list disk
select disk 0
clean
convert gpt
exit
```

3. **Use a different USB drive.** If you are still having trouble, you can try using a different USB drive. Make sure that the USB drive is at least 8GB in size and formatted in NTFS.

4. **Contact Microsoft support for help.** If you are still having trouble, you can contact Microsoft support for help.


i. Here are the steps on how to change MBR to GPT:

1. **Back up your data.** Converting MBR to GPT will erase all data on the disk. Make sure to back up all of your important data before proceeding.
2. **Open Disk Management.** You can open Disk Management by pressing `Windows`+`R` and typing `diskmgmt.msc`.
3. **Identify the disk that you want to convert.** In Disk Management, each disk will be assigned a disk number. Make a note of the disk number for the disk that you want to convert.
4. **Select the disk that you want to convert.** Right-click on the disk number and select "Convert to GPT Disk".
5. **Click "Yes" to confirm the conversion.** The conversion process will take a few minutes to complete.
6. **Once the conversion is complete, the disk will be formatted in GPT.** You can now create partitions on the disk and install Windows.

Here are some things to keep in mind when converting MBR to GPT:

* Converting MBR to GPT will erase all data on the disk. Make sure to back up all of your important data before proceeding.
* Not all computers support GPT disks. Make sure that your computer's BIOS supports GPT disks before proceeding.
* If you are installing Windows on a GPT disk, you will need to use a 64-bit version of Windows.

ii. There are a few reasons why you might not be able to install Windows 10 on an MBR partition table.

* **Your computer's BIOS is not set to UEFI mode.** UEFI (Unified Extensible Firmware Interface) is a newer standard for BIOS that supports larger disks and more partitions than the older BIOS standard. If your computer's BIOS is not set to UEFI mode, you will not be able to install Windows 10 on an MBR partition table.
* **Your computer's hard drive is larger than 2TB.** MBR partition tables can only support disks up to 2TB in size. If your computer's hard drive is larger than 2TB, you will not be able to install Windows 10 on an MBR partition table.
* **Your computer's hard drive has more than 4 primary partitions.** MBR partition tables can only support 4 primary partitions. If your computer's hard drive has more than 4 primary partitions, you will not be able to install Windows 10 on an MBR partition table.

If you are unable to install Windows 10 on an MBR partition table, you will need to convert the partition table to GPT. You can do this using the Diskpart command-line tool. To open Diskpart, press `Windows`+`R` and type `diskpart`.

In Diskpart, type the following commands:

```
list disk
select disk 0
clean
convert gpt
exit
```

Once the conversion is complete, you will be able to install Windows 10 on the disk.

iii. Here are the steps on how to convert MBR to GPT without deleting partitions:

1. **Back up your data.** Converting MBR to GPT will erase all data on the disk. Make sure to back up all of your important data before proceeding.
2. **Download and install a third-party partition manager.** There are many different third-party partition managers available, such as EaseUS Partition Master or MiniTool Partition Wizard.
3. **Open the partition manager.** Once the partition manager is installed, open it and identify the disk that you want to convert.
4. **Select the disk that you want to convert.** Right-click on the disk number and select "Convert to GPT Disk".
5. **Click "Yes" to confirm the conversion.** The conversion process will take a few minutes to complete.
6. **Once the conversion is complete, the disk will be formatted in GPT.** You can now create partitions on the disk and install a 64-bit version of Windows.
