Hi R121567,
Sorry it took a couple of days to answer, I caught a bad case of the flue these last couple of days.
hope this can still help you:
Choice 1) You should choose the largerst partition to recover from. No point in chosing the whole drive.
That’s number 4, all the way down on the first choice.
Choice 2) The file system should be ext4.
Choice 3) This is the foilder you want to recover TO. so you should know where your external drive is. If you’re not sure you can have a look using “mount” (assuming it mounted correctly)
If you still need any help just let me know .
And if you feel like I helpd klick the star
