Is it possible to recover deleted/lost Windows partitions
Partitions function as containers for the data kept on a storage device. The partition table, also known as the Master Boot Record (MBR), the GUID Partition Table (GPT), or something similar, contains information about the partitions, including partition type, size, location, file system, etc.
Using the partition table and boot sector, the computer can identify a partition. On a computer, when you delete a partition, the system doesn't totally erase the space used by it; instead, it only deletes the partition information from the partition table. In addition, other causes such as power failure just damage the partition table, file system, and other info, and the partition data remain intact.
Only if the deleted/lost partition hasn't been overwritten, you can recover it. Hence, you should perform partition recovery on Windows 10/11 immediately once you find the partition lost and stop writing any data to the drive to the partition/drive to avoid data being overwritten.
