    Why else would it erase the disk ... It's an installer ... Yes, Ubuntu will automatically be installed on the selected disk after erasing it and will auto partition and occupy the whole disk. ... "erase disk" means exactly what it says and can be dangerous if the wrong disk is selected. – Raffa May 05 '23 at 18:29
  • Okay that means ubuntu is smart to add its files engine on ssd not on hdd – Abdallah May 05 '23 at 19:45
  • But if I while installation type I select something else option that will delete my files on original old disk I don't want any data to be on old drive also if ubuntu not delete old data can I delete it after installation – Abdallah May 05 '23 at 19:47
  • Yes, you can even format the old HDD from within Ubuntu after installing it on the SSD. – Raffa May 05 '23 at 19:50
  • I got this error /run/user/999 is not owned by us – Abdallah May 05 '23 at 19:59
  • Is that mean the ssd is invalid I just purchased it last two week – Abdallah May 05 '23 at 19:59
  • This error is be displayed with two installation type erase and something else – Abdallah May 05 '23 at 20:00
  • Know I continue but Know I see install window with title everything you need for the office – Abdallah May 05 '23 at 20:04
  • Please see: https://ubuntu.com/tutorials/install-ubuntu-desktop#1-overview for help – Raffa May 05 '23 at 20:05
  • I did all that but now it's take a lot of time – Abdallah May 05 '23 at 20:15
  • I just wait in install window with title everything you need for the office and can use slider just mouse load and load why this time I think the new ssd is not valid – Abdallah May 05 '23 at 20:16
  • Last question please if I select hdd not ssd ubuntu will be installed on ssd – Abdallah May 05 '23 at 21:20
  • Some of the advice here applies to **`ubuntu-23.04-desktop-amd64.iso`** and **`lubuntu-23.04-desktop-amd64.iso`** but not to for example `ubuntu-23.04-desktop-legacy-amd64.iso` and `xubuntu-23.04-desktop-amd64.iso`. Iso files with the installer Ubiquity will write the EFI boot structure into the first internal drive, while the new Ubuntu 23.04 and the current Lubuntu iso files have other installers that can focus completely on a second (for example external) drive. - If the installer does not 'see' the second or external drive, wipe it (remove the partition table) for example with **mkusb**. – sudodus May 10 '23 at 07:42

I have once cloned my hard disk to a brand new SSD of the same size by using a dd command.

sudo dd if=/dev/sda of=/dev/sdb bs=4K status=progress

In my case it took 3,5 hours and it was successful. But beware not to make an error on the cloning direction!

The if= and of= designations were taken from the results of

sudo blkid

and I did it all with a system booted from a USB stick, because I wanted to be sure that neither the installed hard disk nor the installed SSD are mounted. None of the two file systems were mounted during this cloning operation. The number of sectors of the source and target were indentical.

If they differ, one would first have to re-size partitions on the source drive and then move partitions on the source device such that to be used content becomes consecutive (but there may be empty space within the partitions). It all has to fit to the target device.

The disadvantage of this approach is, that the partitions on the cloned hard disk have exactly the same UUIDs, and DiskLabels and so on as the original hard disk. On one hand this ist very good, because all references within the disks remain consistent. But on the other hand, having disks with identical UUIDs and DiskLabels bears much potential for destroying the content on the original hard disk and on its cloned image on the SSD!

Therefore I shut down the computer immediately after this cloning operation and physically removed the hard drive from it.

My hard disk originally had a swap partition (which actually does not make sense on a SSD). I re-sized other partitions to regain this space of the SSD later. Unfortunately I did not write down, how I achieved this step.
