When starting, the tool finds this partition only: Disk /dev/sdb - 128 GB / 119 GiB - CHS 15566 255 63 So, first question: is Intel partition type a MBR? Why does EFI GPT not work even if the disk label is GPT?

I tried searching for partitions with both types, but only Intel was successful. I tried running testdisk, which identifies the partition table type to be Intel (and not EFI GPT). fdisk report the disklabel type to be gpt. So, in the disk with the OS, /dev/sdb, 128GB SSD, there is no partition table. The BIOS still detected the disks properly, so I started a LiveDVD to see what's going on. And with that 640GB HDD, I only have set that disk as locator to store my TimeShift backups, but locked it with TimeShift and I forgot that password/passphrase as well.So, somehow the partition table on my disk went bananas: at the next boot the system would not start, I got repeatedly kicked in the BIOS and I had no viable boot options. I have done nothing with the main disk, after deleting the partitions and recovering the data with DDRescue-GUI. My question is very simple and straightforward: how can I restore my files from my main disk, and/or backup disk? Then I found Testdisk and now that program is trying to read that *.img, which put out a lot of 'invalid FAT boot sector' messages. So I mounted it successfully with Disks Utility, but I did not have succes in reading that *.img-file. Next I tried to mount and read that *.img by DDRescue-GUI and unpack it on another 2TB HDD (Samsung2TB), but it was unable to mount it.

After installing Mint on a 2TB HDD (WD2TB), I found DDRescue-GUI, with which I created a full 1TB *.img from my main disk. So I went on a new journey on how to recover data. So, I deleted first my back up, forgot that and deleted also my main disk and then remembered that I already had deleted my backup.

Because just before that I had a copy of my files also on another disk (640GB HDD), but I forgot that I already had (just) deleted these files on that HDD. In order to rearrange multiple OS' (M20C, W10-64b, Ubuntu Studio), I was to eager in deleting the partition on my main 'disk', a 1TB Samsung 970 Evon Plus.
