My Dell laptop is throwing up a red alert for an impending HDD failure, currently operating with Ubuntu 20.04. I have acquired a new 500 GB SSD for dedicated Linux use, before the above old HDD actually fails and causes data loss. I also possess a Ventoy multi-ISO pen drive with ISO files of 5 flavors of Linux applications downloaded and in ready-to-use condition. I need support for:
(1) How to clone the entire HDD with all its updated Ubuntu 20.04 software features for copying to the SSD to recreate its exact copy, along with other files and folders?
(2) How to make two auto-boot partitions (specifying their recommended sizes) in the SSD, with the primary partition dedicated for exclusive booting of Ubuntu 20.04 on start-up, and the secondary partition by choice when needed, for auto booting of any of the 5 chosen Linux applications from the Ventoy multi-ISO pen drive; whether by “Disks” partitioning tool or from the command line is recommended?
(3) I also possess a 'Timeshift" backup of my Ubuntu 20.04 system on another pen drive.
(4) Any other alternate recommendation/suggestion?
Being new to Linux, technical support for the above shall be highly appreciated, with details of commands (if command line option is suggested) for either of the two stated options, to prevent a goof-up with a new SSD.
