How to partition a hard drive with only one partition without redoing the system

Just find a simulated partition software.

Resizing a partition affects files from other partitions depends on how it is used.

There are two ways to resize partitions: lossy and non-destructive.

Deleting a partition and recreating it is a lossy way. This method is definitely the fastest, but all files will be lost, and you need to back up in advance, which is a lot of work.

Using partition tools to perform lossless adjustments, such as adds, can resize partitions with data, but they are relatively slow and take much more time.

You can also use a professional disk management tool to partition, such as the latest version of the didkgenius partition tool, it has a lossless partition size function, after adjusting the size of your D drive, and then divide the other space into another partition, pay attention to saving after the end, you can do it, it will not affect the data of your D drive. Note that you want to select lossless resize the partition.

Look at the actual situation.

Generally speaking, there is no absolute guarantee of data.

Important things are moved to other partitions first, and resizing the partition may result in data loss from that partition.

Adjusting the files of other partitions with the built-in functions of the system will affect them. You can try software that supports lossless partitions.

It doesn't affect it, it's the most basic function.

No, it's all non-destructive now.

Generally, there is only one main partition, and you can also set up 4 main partitions, but there is only one active partition, and the operating system is generally installed in the active partition, which has boot information, and can take over control after booting the hardware self-test, which is what we call C disk.

As long as you don't repartition, don't overwrite other partitions, etc., just reinstall the system on the C drive, then it won't affect other partitions. In order to prevent incorrect operation, it is better to back up important files.

In addition, it is recommended that the size of all partitions should be different, and the volume labels should also be different, so that it is easier to identify which partition is when formatting and installing the system, and reduce wrong operations.

Reinstalling the system does not affect the other primary partitions.

With DiskGenius software, you can convert the primary partition to the logical partition losslessly.

Win7 will not (support 4 main partitions, including hidden partitions, a total of 4), XP has not tried (it is estimated that it will scramble the partition table), just format the C disk (bar C disk important data backup to the rest of the disk).

Whichever disk you install will format the disk, and the new partition will only be formatted if you want to start from a new partition. But then you are the main partition, so how do you save some of your large files?

No, the main partition can be set to four, and the one that needs to be started is set to the active partition, and the system will default to the drive letter of the active partition as c, that is, if you set the 1:4 partition as the active partition, then the system that starts the main partition will change the drive letter to c: When installing a dual system, it is best to install it in C:

d: Two disks, many software can share ......

Generally, a hard disk can be divided into four primary partitions, but there can only be one active partition.

You can set up two primary partitions, but you need to set up the boot partition.

Yes, if you want to install a dual system, you must use two hard drives.
