I need to install Ubuntu on my Windows 11 computer, basically I want to replace Windows 11 with Ubuntu LTS (the recent one), but I have some questions.

My aim is to install Ubuntu on my SSD, by using the option "erase disk and install ubuntu" on the installation wizard, and all of personal data is stored on secondary HDD, having two partitions under GPT scheme, so will my data that is stored on SDD be safe and accessible after installing Ubuntu?

Second, I got a pop-up while running the wizard saying

The installer has detected the following disks have mounted partitions " /dev/sda, do you want the installer to try to unmount the partitions on these disks before countuning, if you leave them mounted, you will not be able to create, delete or resize on thesedisks, but you maybe able to install to exisiintg paritions there.

What does that means? And what should I do here. I don't want to loose any data that is stored on the HDD, and the SSD doesn't have any data.

First: If you will choose erase every thing it will delete the whole hard disk data so you have 2 choice:

1- Choose the option of some thing else and delete only the space the you don't need and create a new 2 partitions on it first one make it as swap it's depends on your RAM random memory make it the same space or double, the 2nd partition for the system choose format type as EXT4 , name it as / and you are done.

2- You can erase every thing as you want and after that you can make data recovery, but first 1 is better.

Second: Your mount partition will make the partition unable to be write able on it, so you have to unmount it if you will erase all disk to don't get error, don't use any partition on hard disk will the setup running on "Try Ubuntu", you can do other stuffs Online or play Ubuntu simple games that loaded on the USB or CD.
