It's necessary for some users to know how to upgrade the C drive, here we'll provide you with detailed instructions.

│Before you do

Before your migration, you should pay attention to the following things and do some preparation:

✍ Connect the HDD/SSD to PC: If your computer is a desktop, you can install the HDD/SSD directly. If your computer is a laptop, you must prepare an external SATA to USB adapter in advance to securely connect the new hard drive and the laptop.

✍ Adjust the partition style: The partition style must be compatible with boot mode (UEFI and Legacy BIOS). To avoid changing the boot mode after cloning, you’d better make the partition style of the HDD/SSD consistent with the partition style of the source disk. So, please convert the SSD to GPT or MBR (if necessary). 

✍ Check the space of the destination drive: The free space of the destination must be larger than the current OS partition, or the migration will fail.
