Resetting reinstalls Windows 10, but lets you choose whether to keep your files or remove them, and then reinstalls Windows. You can reset your PC from Settings, the sign-in screen, or by using a recovery drive or installation media.
Reset your PC from Settings
Select the Start button, then select Settings > Update & Security > Recovery .

Note: The option in Settings to go back to your previous version of Windows is only available for a limited time after upgrading.
Info for Windows Insiders
If you’re an Insider and the current preview build isn’t working for you, select the Start button, then select Settings > Update & Security > Recovery . Under Go back to the previous version of Windows 10, select Get Started. This won’t remove your personal files, but it’ll remove recently installed apps and drivers, and change settings back to their defaults.
Going back to an earlier build won’t remove you from the Insider Program. When the next preview build is ready, it’ll be installed on your PC.
This option takes your PC back to an earlier point in time, called a system restore point. Restore points are generated when you install a new app or driver, and when you create a restore point manually. Restoring won’t affect your personal files, but it will remove apps, drivers, and updates installed after the restore point was made.

If you don’t see the restore point that you want to use, select the Show more restore points check box to see more restore points.
If you’re not seeing any restore points, it might be because system protection isn’t turned on. Here’s how to check:
In the search box on the taskbar, type control panel,andthen choose it from the list of results.
In the Control Panel search box, type recovery.
Select Recovery > Configure System Restore > Configure and see if the Turn on system protection option is selected.

If the Turn on system protection option is selected, continue with step 6.
You’ll see a list of items that will be deleted if you remove this restore point. If you’re OK with the deletions, select Close> Next > Finish.
Top Two Ways to Recover Lost Partition in Windows 10, 8, 7
Partition gets lost or missing in Windows 10? Here we share two ways to help you recover lost partition in Windows 10 easily and effectively.
By Ivy / Last Updated January 13, 2021
“Oops! I’ve accidentally lost my partition!”
Generally, you should partition a storage device into one or more partitions before you use it to store data. A partition can be created either during Windows installation, in Disk Management, by using the DiskPart command, or through a specialist third-party tool. However, sometimes you might find your partition is lost, and you are unable to see it in Windows File Explorer. In Disk Management, the lost partition will appear as extra unallocated space rather than the original partition.
«I have a Windows 10 computer and I have made a big mistake! I have a hard drive that stores all my media files, but I accidentally deleted the volume and all files are gone! It now shows “Unallocated”! Is there any way to recover the deleted volume on Windows 10 and get back my files?”
This is a real example from my friend. Once a partition gets lost, deleted, or corrupted, all files in that partition are likely to be lost at the same time. In this case, you have to recover lost partition in Windows 10 and then your files will be restored.
Tip: If you want to avoid further data loss before recovery, you should pay attention to the following things.
в–ё Do not perform any operation on the hard drive.
в–ё Do not reformat the hard drive.
в–ё Do not add new items to the partition.
в–ё Do not rebuild the partition table.
Why does a partition get lost in Windows 10?
Before trying to get back the lost partition, you may want to figure out why a partition gets missing.
Corrupted partition table. Due to user error, or a virus, the partition table may be damaged or corrupted, and then led to partition loss.
User error, such as through incorrect DiskPart clean commands.
Power failure.
Bad sectors. If your partition was damaged due to a bad sector, your computer may not recognize it and then show the partition as unallocated space.
Repartition hard drive. If you repartition the hard drive, all the existing partitions will be deleted.
Loss of the volume label, drive letter, or partition name.
Hard drive changes due to an upgrade.
Is it possible to recover lost partition in Windows 10?
The majority of users think the partition is gone forever after deleting or cleaning. But you still wonder if it is possible to recover deleted volume in Windows 10 because you cannot afford data loss owing to partition loss.
Fortunately, you can recover deleted partition using a professional partition recovery tool, because your computer recognizes a partition by its partition table and boot sector. When you delete a partition on the computer, the system just removes partition information (eg: partition type, size, location, file system, etc.) from partition table rather than wiping the area occupied by the deleted volume completely. At last, you just cannot see that partition in Disk Management or File Explorer.
How to recover lost partition in Windows 10?
As mentioned above, partition loss can be caused due to a variety of different reasons. You can try the following methods — hopefully, one will work for you!
Method 1. Recover a lost partition using CMD
If you think your problem was caused by the loss of the volume label, drive letter, partition name, you can try this method to assign a drive letter to it and make it visible again in File Explorer.
Step 1. Find the lost partition in Disk Management. You can press “Win + R” and type “diskmgmt.msc” in the Run window, and then press OK to open Disk Management. If a partition is deleted, the disk space will be marked as Unallocated. Remember the partition size.
Step 2. Run CMD as administrator.
Step 3. Type diskpart in the window and press Enter.
Step 4. Type list disk and press Enter key. After that, you will see all disks on the computer.
Step 5. Type select disk # and press Enter (Replace # with the number of the hard drive that contains lost partition).
Step 6. Type list volume and press Enter.
Step 7. Type select volume # and press Enter (replace # with the number of lost partition).
Step 8. Type assign letter=# and press Enter (Replace # with an available drive letter).
Step 9. Exit this window and see if you can access that partition.
Method 2. Recover Windows 10 lost partition with an easy way
If the partition is deleted and then get lost, you can use a professional recovery program like AOMEI Partition Assistant Professional to recover the missing partition. It is one of the market-leading partition recovery products. It is designed to recover lost partitions in Windows 10, 8, 7, Vista, and XP with an easy step by step process that anyone can follow. To recover lost partition in Windows Server 2019, 2016, 2012 and more, please use AOMEI Partition Assistant Server.
вќ¤вќ¤вќ¤вќ¤вќ¤
AOMEI Partition Assistant Professional is a versatile partition manager, with which you can easily manage your disk partition. It not only has the basic functions that Disk Management offers like “create partitions, delete partitions, format partitions, change drive letter, shrink partition, extend partition”, but also has many advanced features such as “convert MBR and GPT without deleting partitions, move partition, clone partition, merge partition, format large hard drive (over 32GB) to FAT32, allocate free space from one partition to another, clone hard disk”.
To recover lost partition in Windows 10 via AOMEI Partition Assistant Professional, follow the steps detailed below. (PS.: you can download the demo version for a free trial).
Step 1. Find the lost partition in Disk Management. Install and open AOMEI Partition Assistant.
Step 2. Click the disk you want to recover and select Partition Recovery Wizard on the left panel. When you get into partition recovery wizard, select a disk that you want to recover. Click Next.
Step 3. Select Fast Search. It is recommended that you select this option the first time as it is faster than Full Search. If you are unable to recover the lost partition using Fast Search then I recommend you try the Full Search option.
Step 4. Select the lost partition and click Proceed.
Step 5. Click Finish to exit this window after you see the congratulations message.
Then you can go to Windows File Explorer to check if the partition is restored. If you did not make any further operations on the partition since it is deleted and lost, the inside data will also be back and accessible now.
The way forward
In most circumstances, you can recover lost partition in Windows 10, but you should make sure you fully understand the reasons why the partition was lost to avoid it happening again in the future. If you have followed all the above steps and you still can’t use the files in your partition, then you should check for bad sectors. You can do this via the Check Partition function in AOMEI Partition Assistant.
I always suggest that you create a backup image for your partition in case anything happens. Once something goes wrong it’s far easier to restore your computer back to its previous state with a system image.
