When encountering the problem of "Unable to delete partitions", first confirm whether you have entered the correct installation stage and have administrator rights; secondly, check whether the partition is occupied, whether the disk is a dynamic disk, whether there is a hardware error or BitLocker encryption; then try the following methods to solve it: 1. Use DiskPart to clear the disk; 2. Convert the dynamic disk to a basic disk; 3. Turn off Secure Boot in the BIOS or enable Legacy mode; 4. Replace the hard disk interface or data cable to troubleshoot hardware connection problems; 5. Adjust the order of deleting partitions or formatting before deleting the volume; If it still cannot be solved, it may be a failure of the installation media or the hard disk itself. It is recommended to replace the USB disk or ISO file for further troubleshooting.
When installing Windows systems, it is common to encounter the problem of "unable to delete partitions". It usually occurs when you are trying to clean up your hard drive, repartition, or prepare to install a brand new system. The root causes of this problem are diverse, but in most cases it can be solved with some simple methods.

Preparation before using disk management tools
Before trying to delete the partition, make sure you have entered the installation interface correctly and select the "Customize: Install Windows only (Advanced)". If you don't see this option, you may not have reached the stage where you can operate the partition.

Also, make sure you have administrator privileges. If you are using a USB flash drive to start the installation, also make sure that the installation media is complete and not damaged.
Why can't the partition be deleted?
There are several common reasons why you cannot delete partitions:

- Partitions are occupied : such as system reserved partitions, recovery partitions, etc. The Windows installer sometimes restricts you from deleting them directly.
- The hard disk is in the dynamic disk state : If it is a dynamic disk, regular partitioning operations will be disabled.
- There is an error or a bad disk : Hardware issues may also cause the partition table to be modified.
- BitLocker encryption is used : the encrypted disk needs to be decrypted before partitioning is performed.
If you see a prompt saying "This partition cannot be deleted", don't rush to force operations and troubleshoot these common reasons first.
Summary of solutions
Here are a few practical operation suggestions that apply to most situations:
-
Use the DiskPart command line tool
On the installation interface, press
Shift F10
to bring up the command prompt and enter the following command:diskpart list disk select disk X (X is the disk number you want to operate on) Clean
This command clears partition information of the entire disk. Note: This will delete all data, please back up important files in advance.
-
Convert to basic disk
If your disk is a dynamic disk, you can convert it to a basic disk in other systems. Or use a third-party tool to process it before trying to install it.
-
Turn off Secure Boot and enable Legacy mode
Some motherboard settings affect partition recognition. Try turning off Secure Boot in the BIOS or switching to Legacy boot mode and re-enter the installer.
-
Replace the hard disk interface or data cable
If you suspect it is a hardware problem, you can try replacing the SATA interface or data cable to troubleshoot problems caused by unstable connections.
Small details that are not complicated but easily overlooked
Sometimes the problem lies in the partition order. For example, if you format a partition first but cannot delete it, it may be because it is the currently selected system boot partition. At this time, it is recommended to start deleting from the last partition and gradually move forward.
There is another trick: After clicking "Drive Options (Advanced)" in the installation interface, try "Format" the partition first, and then "Delete volumes", which can sometimes bypass the restrictions.
Basically these are the methods. Most of the time, using DiskPart to liquidate is the most direct way. If it still doesn't work, it may be due to hardware problems or the installation image itself, you can try changing a USB drive or ISO file.

Force shut down three times to enter the recovery environment, try to start repair or enter safe mode to troubleshoot driver and software conflicts; 3. Check the hard disk bad channel, clean the memory gold fingers and replace the slot to test the hardware problems; 4. Finally, you can try to reset the computer or install the system in a brand new way to solve it, and give priority to using the official website pure ISO mirror.

Connecting a second monitor when installing a Windows system will not affect the installation process, but the following things need to be paid attention to to ensure that the dual screens work normally: 1. There may be only one screen display during the installation process, and the main display device in the BIOS can be adjusted or the interface can be replaced; 2. After the installation is completed, select the display mode through Win P, and adjust the resolution, position and main display in the display settings; 3.
