You can solve the problem by setting your computer's default boot disk to the hard disk where the D drive is located as the first boot disk in the boot BIOS.

Cause analysis: If the situation you described occurs, it means that your computer has two hard disks, in which the old system is installed on the hard disk where the C drive is located, and the new system is installed on the second hard disk where the D drive is located. In the BIOS configuration of your current computer, the hard disk where the C drive is located is used as the first boot disk by default, and the disk has been formatted by you, so the system cannot find the boot file.

Solution: Go to BIOS settings and set the hard disk where the D drive is located as the first boot disk. Depending on the computer brand, the specific way to modify the BIOS is different, please find the corresponding settings according to your computer brand.

The steps are as follows: 1. When the computer is turned on, press F10 or F12 (the keys are not the same, find the corresponding button of your own brand), you will see the following options, that is, you will be asked which device you choose to boot on, generally your computer will choose one of the hard disk devices by default (this is the hard disk where your current C disk is located by default);

At this time, you need to change the default selection to another hard disk of your computer (use the up and down arrows on the keyboard to move it to select, press enter to confirm);

2. If the above interface does not appear when you boot up, you can also press "Delete" or "F2" to enter the BIOS settings (similar to the following interface), and then find "Startup", (or similar to "Boot Device", "Boot Order");

3. After finding an interface similar to the "BOOT" boot list, you will see a lot of devices, such as "HDD", "ST", etc., which are basically hard disk devices, at this time, you can use the up, down, left, right arrows or shortcut keys of the keypad to move your hard disk device through the prompts below, and move it to the first place.

4. Note: There are various types of BIOS, and detailed and accurate screenshots cannot be provided. Some computers have clear words such as "1st", "2nd", and "3rd", and "1st" represents the first boot and sets the hard disk where your D drive is located"1st", and then save to exit.
