What Does the System Reserved Partition Do?
When it comes to moving system reserved partition to another drive, the first thing you need to know is what does the system reserved partition do. This partition contains two important things:
- The Boot Manager and Boot Configuration Data: When your computer boots, the Windows Boot Manager starts up and reads the boot data from the Boot Configuration Data (BCD). Your computer boots the boot loader off the System Reserved partition, and it boots Windows from your system drive.
- The startup files used for BitLocker Drive Encryption: If you ever decide to encrypt your hard drive with BitLocker drive encryption, the System Reserved partition contains the necessary files for starting your computer. Your computer boots the unencrypted System Reserved partition, and it will decrypt the main encrypted drive and boot the encrypted Windows system.
When do you need to move system reserved partition?
There are two situations you may want to move system reserved partition.
Situation 1: The system reserved partition and C drive on the different disk.
Sometimes, you may forget to disconnect the other drive when you install Windows 7/8/10. Then, you may find your C drive on disk 1 and system reserved partition on disk2. So you may want to move system reserved partition to your disk 1.
Situation 2: The system reserved partition on the disk experiencing smart error
After you use your disk for a period of time, you may find this disk experiences smart error. And your system reserved partition is on the disk. So you may want to move system reserved partition and system partition to a healthy disk.

Move system reserved partition with Windows built-in tool
Whatever problems you encounter concerned to your computer, the first option you may choose Windows built-in tool. And the most attractive of Windows built-in tool is that you can use it without costing you a cent.
Now, let's see the specific steps.
Step 1: Create a repair disc. Once your computer cannot boot successfully, you can use a system repair disc to perform Startup Repair.
Step 2: Create a new simple partition (around 100MB) on the disk 0 with disk management. To open disk management, you can click “Win+R” and type diskmgmt.msc in the run box. Then right click the unallocated space, then choose New Simple Volume. If you do not have an unallocated space on the disk 0, you can shrink partition first.
Step 3: Assign a drive letter for your newly simple partition (Z:)
Step 4: Copy everything from the system reserved partition to your newly simple partition (Z:), Including Boot folder, bootmgr, BOOTSEC.BAK

Step 8: Restart your computer and see if it can boot successfully. If it fails, run Startup Repair.
After it can boot successfully, you are supposed to remove the old system reserved partition on the disk 1.

Do not worry about it. And I will provide you another way.
Another way to move system reserved partition to SSD
Directly move files or folders from a partition will directly leave some problems, especially when you copy files or folders from a partition concerned to system related partition.
So it's time to find a new simple way. I recommend you to use a disk cloning software AOMEI Backupper. With it, you can move system reserved partition effortlessly without leaving potential problems.
Now, let's see the specific steps:
Step 1: Download AOMEI Backupper standard, install and launch it.
Step 2: Select Partition Clone on the following interface.
Step 3: Select System Reserved partition on the disk 1, then click Next.
Step 4: Select the unallocated space on your disk 0. If you do not have an unallocated space, you can resize partition first. After that, click Next.
Step 5: Preview the Source Partition and Destination partition. To prevent you delete System Reserved partition mistakenly, you need to click Edit the size of partition and set Drive Letter as None, then Create the unallocated space as Primary Partition. Only the primary partition can be set up as Active. Aside by that, you need to tick Align Partition to optimize for SSD if your destination is SSD disk. This feature can accelerate the reading and writing speed of your disk. After set up all settings you need, back to Operation Summary interface and click Start Clone.
After that, you need to mark your new System Reserved partition as Active. If you mistakenly set System Reserved partition as Logical Partition, you need to convert it to primary partition first.
Then restart your computer and check if it can boot successfully. If your computer successfully boots, you have succeeded in moving System Reserved partition to another drive. Then you can delete the old System Reserved partition.
You can successfully move System Reserved partition another drive with disk management and system repair steps, but this method may leave some potential problems. To avoid unnecessary trouble, you would better choose the second way to move your System Reserved partition.
