I had a 250GB SATA SSD and 500GB SATA SSD. I first used Ubuntu OS installed on the 250GB SSD and used the 500GB SSD to store my other files. Then I decided to dual boot Windows 10 to use Office package.
I got another 500GB NVMe and installed Windows on that. After installation I saw thet 500GB SATA SSD its not listed in "My PC" because its ext4 file format.
I found it in Disk Management but it showed as "Unallocated". I logged out from Windows and logged in to Ubuntu, and saw that the ext4 drive was formatted and had a new 16MB partition type shown as "Microsoft Reserved". I deleted it and created again full ext4 partition. I tried using disktest but no help.
Is there any other way to recover data from that ext4 drive?
