The reasons and fixes for "Windows 10 couldn't be installed"
When upgrading to Windows 10, it's not uncommon to encounter errors like "We couldn't update the system reserved partition" or "Failed: 1 update". These issues can be caused by insufficient free space for the system reserved partition or problems with the Windows update process. To resolve these errors, you can try freeing up space on the system reserved partition or check for issues with the Windows update process, depending on the specific error message you receive.
Way 1. Free up space on system reserved partition
1. To open the Disk Management console, press the Windows key + R to open the Run dialog box, type "diskmgmt.msc" in the box, and then press Enter.
2. At the Disk Management screen, right-click on the system reserved partition and select "Change Drive Letter and Paths".
3. At the next screen, choose "Add" and enter "G" for the drive letter.
4. Click "OK".
5. To perform a disk cleanup, type "disk cleanup" in the search box and select Disk Cleanup.
6. In the pop-up Drive Selection window, select the G: drive and click "OK".
7. Follow the instructions to complete the disk cleanup.
After upgrading to Windows 10, there should be sufficient space on the SRP to upgrade. Be aware that you should change the drive letter to "None" before trying to upgrade to Windows 10. If Windows 10 couldn't update the system reserved partition after running Disk Cleanup, you can extend the SRP.
Way 2. Extend system reserved partition
To extend the System Reserved Partition (SRP) without losing data, you can use free partition software like Qiling Disk Master Standard. This tool can help you extend the SRP even when it's right behind the system partition (C: drive), which is typically the case. By using Qiling Disk Master Standard, you can safely extend the SRP, making more space available for your system without compromising your data. You can download and follow the steps provided by the software to achieve this.
1. Right-click on the C: drive, select "Resize Partition", and proceed with the process, taking note that a fresh Windows 10 install on a blank disk may only require a few hundred MBs of unallocated space.
2. To allocate the unallocated space next to SRP, drag the slider bar from left to right. This will ensure that the unallocated space is adjacent to the SRP partition.
3. To finalize the partition layout, click on the "Proceed" button. This will apply the changes and finalize the partitioning of the drive.
When the upgrade process is completed, you will be prompted to restart your computer and complete the operations under PreOS Mode, after which your computer will reboot and allow you to upgrade to Windows 10.
If you had partitioned your hard drive before installing Windows, you wouldn't have had a system reserved partition, which could be a solution to fix the Windows 10 installation problem. Alternatively, you could merge the system reserved partition into the C: drive, but this is not safe and not recommended by Microsoft. Another option is to use a disk management tool to add space to the system reserved partition from another partition on the same disk.
Way 3. Stop and restart the Windows Update Service
Step 1. Press "Windows" + "R" to open "Run" window.
Step 2. Input "services.msc" and hit Enter to open "Services" window.
Step 3. Locate "Windows Update" services, right-click it and choose "Stop".
Step 4. Close this window and open "Services" window again;
Step 5. locate "Windows Update" services, right-click it and choose "Start".
Way 4. Delete "Rollback" in Registry
Step 1. Open "Run" window, input "regedit" and click "OK" to open Registry Editor.
Step 2. Navigate to the following path:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\OSUpgrade\Rollback
Step 3. Right-click "Rollback" and choose "Delete".
