These are command-line instructions for the "Diskpart" utility in the Windows operating system: 1. **diskpart**: Launches the Diskpart tool, which allows users to manage hard disks and other storage devices through a command-line interface. 2. **list disk**: Displays all the disks connected to the system. This will show the number, size, and other information for each disk. 3. **sel disk 0**: Selects disk 0 as the target for subsequent operations. The number 0 refers to the first disk. You can change this number to select a different disk based on your needs.

Run a disk partitioning utility to start repairing your UEFI errors.

Step 2: When Disk 0 is selected, type list vol and press Enter.

Select the disk and volume for which you want to set the volume ID:

Now, Diskpart will display the complete list of volumes on your computer. Find the UEFI volume: The UEFI partition will be on Volume 2.

• sel vol 2
• set id=c12a7328-f81f-11d2-ba4b-00a0c93ec93b

• When the process is complete, type exit.

2. To repair the boot record, open CMD and type in the following command lines:

< li >< strong > bootrec /fixboot

• When the repair is complete, type exit.

2. When you're done, type exit in the command prompt and restart your computer.

With the UEFI boot issue resolved, your computer should now be able to boot into Windows 11/10/8/7 without any problems.

Method 4: Change Your BIOS Settings

You need to choose the boot mode according to the disk type in your system. If you're booting from an MBR system disk, you can select Legacy support instead of UEFI in the boot mode. If you're booting from a GPT system disk, you'll need to choose UEFI.

How to Enter BIOS: Common keys to enter BIOS are “F1,” “F2,” “F10,” “Delete,” and “Esc.” On older machines, a combination like “Ctrl” + “Alt” + “Esc” or “Ctrl” + “Alt” + “Delete” may be required. Press one of these keys while your computer is booting up to access the BIOS screen.

Method 5: Add a Disk Drive to Fix Windows 11/10 Boot

When you replace a RAID with a different controller, or swap in an NVMe SSD for a SATA or IDE disk, you may run into boot problems. You can manually add the driver to the Windows recovery image using the following Windows command-line procedure.

Add a driver to an image using the Dism command: /Image:X: /Add-Driver /Driver:"Y:\Z.inf" Here's what each parameter means: - `/Image:X:` specifies the directory where the image you want to modify is located, with X: representing the target drive letter. - `/Add-Driver` is the command used to add a driver to the image. - `/Driver:"Y:\Z.inf"` denotes the path to the driver's INF file, with Y: being the drive letter of the drive containing the INF file, and Z.inf being the name of the INF file.

(X stands for the character of the disk where the Windows boot partition is restored, and the path to the Inf file of the driver is within the double quotes.)

Method 6: Fix Windows 11/10 Boot by Changing SATA Mode

After restoring an old version of XP, blue screen or cyclic startup may occur. You can try to switch to IDE mode to start up.

If you encounter boot issues after upgrading from an old HDD to a new SSD, ensure that your BIOS is set to enable AHCI boot. If it's set to RAID mode, make sure the correct RAID driver is added to the cloned system.
