A required drive partition is missing" Error in Windows](https://www.datanumen.com/blogs/wp-content/uploads/2018/05/unable-to-reset-pc.jpg "\"Unable to Reset PC. A required drive partition is missing\" Error in Windows") ## 1. Run CHKDSK First off, your computer disk may be very likely to suffer some errors, such as bad sectors. In this situation, you need to check and repair disk errors via CHKDSK. It demands you to reboot your PC from an installation media. Then, you can access “Repair your computer” > “Advanced Options” > “Command Prompt” by following onscreen wizards. Later, in Command Prompt, you can use the “CHKDSK /c” line. ## 2.

This can be accomplished by the snap-in tool- [System File Checker (SFC)](https://www.datanumen.com/data-recovery/guides/system-file-checker/). Like the above solution, get access to Command Prompt and use “sfc scannow” command line. ## 3. Change Active Partition As the error message suggests, the require drive partition is missing. Therefore, it is essential and a wise idea to change active partition, which is the one that BIOS will detect it as the booting partition. Now, you can trigger Command Prompt and take the following steps. 1. First off, in Command Prompt, enter the following commands: “diskpart” > “list disk”. 2. Then, select the specific disk, such as “select disk 0”. 3. Next, input “list partition”. 4. Later, select the specific partition, such as “select partition 0”. 5. After that, mark it active partition, use “active” and hit “Enter”. 6. Finally, type “exit” to exit “diskpart” and Command Prompt. ## 4. Run Bootrec.exe Tool In addition, there is a chance that the MBR or BCD file is corrupted. In this case, it is essential to correct, repair and even rebuild the file. You can undertake the task with the bootrec.exe tool. You can run command prompt as usual. Then, make use of the command lines in turn – “BOOTREC /SCANOS” > “BOOTREC /FIXMBR” > “BOOTREC /FIXBOOT” > “BOOTREC /REBUILDBCD”. ## 5.
