System Reserved Partition Recovery in Windows 11/10/8/7

If you accidentally delete the system reserved partition in Windows 10, it can cause boot problems or system update issues, such as the "We couldn't update system reserved partition" error when installing Windows 11/10. However, don't worry, as there are effective solutions to recover the deleted system reserved partition and resolve the boot errors on your PC.

Method 1. Restore Deleted System Reserved Partition Windows 11/10 with WinPE Bootable Disk

If you've deleted the system reserved partition in Windows 11/10 and are unable to boot, creating a WinPE bootable disk can be a lifesaver. This disk should be created beforehand, or on another healthy computer, to help recover and repair the system reserved partition. By creating a WinPE bootable disk, you'll have a reliable tool to troubleshoot and fix the issue, allowing you to restore your system to a working state.

Qiling Partition Master allows you to create a WinPE bootable disk, which can be used to reboot the system and recover the deleted system reserved partition using the Partition Recovery feature with ease.

Step 1. To create a bootable disk of Qiling Partition Master, prepare a storage media such as a USB drive or CD/DVD disc, and correctly connect it to your computer.

Step 2. Launch Qiling Partition Master, find the "Create bootable media" feature on the tools page and click on it.

Step 3. You can choose to save the ISO file to a USB, CD/DVD, or local drive, and then proceed with the process.

After creating a Qiling Partition Master WinPE bootable disk, you can successfully manage your hard disks and partitions through the bootable drive whenever your computer fails to boot normally. This means you can perform various disk and partition operations, such as creating, deleting, resizing, and formatting partitions, all from a bootable environment. This can be particularly useful in emergency situations where your computer is unable to boot up normally.

In a WinPE environment, if you have RAID drives, you need to load the RAID driver first by clicking on "Add Driver" from the menu bar. This is because some devices, like RAID or specific hard disks, may not be recognized without their respective drivers installed.

After creating the WinPE bootable disk, you can proceed with restoring the system reserved partition deleted by following the same steps in Method 2.
