Are you looking for a guide that can help you to extend C drive from another disk? On this page, we'll be showing you the complete procedure in expanding SSD system drive to another drive without losing any data or booting issues.

When to Extend C Drive from Another Disk
In some of EaseUS's previous articles, we mainly discussed how to fix the listed issues here with free or unallocated space on the same disk:
- Extend C drive without formatting
- Extend C drive in Windows Server 2019/2016
- C drive is out of space
- Merge C drive with D drive
- Merge disk 0 to disk 1, etc.
You can efficiently resolve the problem by extending the C drive with unallocated or free space or increasing the system drive. When there is no unallocated space or free space on the target disk, you can even convert two disks to dynamic and merge them as one to fix the problem.
However, when you are with the listed case here, you'll need a solution to expand SSD C drive across disks:
- SSD has only one system partition.
- There is no unallocated space left on the system SSD disk.
- The SSD C drive is running out of space.
- SSD C drive becomes read, or computer warns with low disk space error.
So how to expand C drive from another HDD or SSD? Follow the full guide below, and you'll successfully get rid of the SSD C drive full issue with ease.
#1. Prepare or Add a Second Drive to PC
Note that if your system has a second disk configured on the computer, you can directly jump to the second part and continue.
However, if your computer only has one SSD configured as the system C drive, you'll need to add and set up a second hard drive or SSD. And here are the steps:
Step 1. Purchase a new hard drive or SSD.
Note that the second hard drive or SSD should own equal or even bigger storage space than the system SSD drive.
Step 2. Install and configure the new HDD or SSD to your PC.
- Move the computer case, insert the new disk to the PC via the SATA and power cables.
- Close computer case, enter Disk Management, right-click the new disk, and select "Initialize Disk".
- Configure the disk type as the same as the source system SSD - MBR or GPT.

After configuring the second drive on your computer, it's time that you turn to reliable disk manager software for help. EaseUS Partition Master, with its newly released feature - Expand C Drive is here to help.
