Q: How to delete the 200M hidden partition created by Win7?
A: Users who have installed Windows 7 will find that the system will automatically draw a partition with a size of 200MB. This is a hidden partition. It is cumbersome to delete it. If you use DM and other partitioning tools to delete it, it will damage the partition table of the hard disk, causing other partitions to disappear (the drive letter is not displayed). Even if you use Windows 7's own tools to delete, it will cause the hard disk partition table to be in an error state, and there is a problem of missing files.
To delete this 200MB hidden partition, the correct way, please follow the steps below:
First, use WinPE boot system with partition tool, be sure to use WinPE boot on CD or U disk, do not Boot with WinPE installed on the hard disk.
Second, use a partitioning tool such as WINPM, delete the 200MB hidden partition, and then merge this deleted partition into another partition. Then set the installation partition where Windows 7 is located, such as the C drive, as the active partition.
Third, click “ start & rdquo; menu, select “ program & rarr; command prompt & rdquo;, enter “c:\\windows\\system32>bcdboot c:\\windows /sc:” and enter, Fix booting of Windows 7.
Fourth, restart the computer into Windows 7, the problem has been solved.
Tip: Do not delete the existing partition of the hard disk when installing Windows 7, and do not create a new partition. Be sure to select the existing partition to install. Only in this way can you avoid the 200M hidden partition automatically created by Windows 7. If it is a new hard drive, you can use other Windows systems or partitioning tools to divide the hard drive into zones. It is best to use another Windows system to install the partition, after the zone is divided, you can exit the installation and restart, and then use Windows 7 to start the installation.
