Preface
Why does this problem occur?
Previously, the PC was equipped with Windows+Ubuntu dual system. Since Centos was configured under the virtual machine, I uninstalled the Ubuntu system. Unexpectedly, the Windows boot entry was deleted by swiping. as the picture shows:
Initially, Boot Manager showed that Boot Manager is Missing, and the EFI USB Device was taken later when the system was reinstalled.
solution:
Download the system image from Microsoft's official website, use Microsoft's official reinstallation assistant, and reinstall the system through a USB flash drive.
Solution steps:
Create a Windows 11 installation:
Download the official creation tool:
Download link: https://www.microsoft.com/zh-cn/software-download/windows11
Here, we choose the second option: bootable USB (specific requirements are as shown in the figure, please make sure your computer can run Win11)
Installation process display:
Here, we choose to create media using a USB flash drive
Because the home Chinese version was pre-installed on the computer before, and Windows has been associated with a Microsoft account, I chose this way.
Wait patiently, it will take about 10 to 20 minutes. Do not eject the USB flash drive in the middle.
Enter Boot Manager mode (Lenovo Xiaoxin series: Restart + F12)
After completing the creation of Win11 media, restart the computer and enter Boot Manager mode, select the USB boot item to enter the reinstallation page;
Note: Different brands of computers have different keys to enter Boot Manager;
Set to suit your preferences
Note that here I deleted the C drive and D drive, and then the unallocated space appeared. Just select the unallocated space.
If your computer's non-system disk contains important data, please do not delete the non-system disk and operate with caution;
Two solutions for drive not found:
Notice:
If the computer does not find the drive at this time, it is most likely caused by the Intel Core 11th generation equipped with Intel VMD technology;
At this point, you have two solutions:
Option One:
1. Go to the official website of your computer brand to download this driver: IRST driver
2. Then extract only the driver to the USB flash drive:
Choose to decompress only
Add this driver folder to the USB flash drive
Then restart and enter the installation program;
If the problem is still not solved, please adopt the second option:
Option II:
1. Restart the computer and enter the BIOS settings: (Lenovo Xiaoxin: Restart + F2)
2. Enter the system settings: 1. Turn off the Intel volume management device; 2. Select AHCI (disk boot) for the SATA controller
3. Then restart +F12 to enter Boot Manger and repeat the process.
Post-installation settings:
suggestion:
1. Add another American keyboard;
2. It is best not to name the device the same as before to prevent confusion;
Regarding Windos activation issues:
Please log in to your computer's previous Microsoft account and automatically activate Windows online;
