2 questions: [1]Does fastboot need to be off , [2]disappearing backups

[r0n]

Thank you for the feedback!

I hope you can identify the root cause of this issue and share it here, as it will be helpful to other users. Thanks.

Sorry the explanation below might not make sense I highly suggest to do the "My advice" part below to just avoid any problems issues.

I think I have found the issue.
In windows when I right click the drive (the drive with the issue) > properties > Security > 'Group or usernames'  -> "Users" was set to read & execute only. I added the read and write permissions to it. Then rebooted into linux-live and saw that the drive this time was actually read AND write.

I checked this in the linux-live environment by right clicking the drive and then properties, It showed a bit different then the other drive on which I made image succesfully, but still the 'write' was now present on the drive that had the issue.

I then booted hasleo backup through usb and tried again to make the image on the drive that had was set to read only originally.
Now it succeeded! I'm almost sure this is a permission issue I do not know how/when the drive had it's write permission outside windows removed. And I do not advise to follow my solution unless you know what you are doing.

Still two strange things:

• The drive on which I could make the backup successfully has set the "Users" permission for 'write' unchecked in windows(not set!!!) However in linux-live environment it shows read/write allowed .......
  
• When doing a backup in hasleo on the drive that was only 'read' the backup succeeds and validation of the backup also succeeds BUT when booting in windows the backup does NOT exist...
  

 
MY ADVICE:

• Just do a test-backup on the drive(s) you plan to do backups on, if backup exists in windows then everything should be fine.
  
• If backup is "gone" in windows then start checking/doing things like: encryption, drive-check, drive permissions etc...
  
• And don't use very long path's and filenames.
  

I used this linux live environment on an usb:
https://www.linuxliteos.com/

The latest version is 3GB contains all the necessary tools you might need and (in my case) booted old pc's (11+ years old) and a new pc (1 year old). But use whatever works best for you, there might be better distro's, this just worked for me.
