hello how i can remove manjaro from my ssd hard that i also installed windows on but in different partition
and install another linux instead manjaro ?
can i just boot another linux and install it on the partition that i installed manjaro on it?
… so you don’t want to remove it, but replace it with something else 
Instruct the installer of whatever you want to install to use the same partitions that the previous install used - re-format those partitions, then install.
No guarantees whether it will mess with your ability to boot Windows - what and how “they” do it is dependent on whatever variant of linux you use.
and as always: have a backup (plan) and a way to deal with possible glitches

my only backup is deleting everything
Bit rude asking one Distro Forum how to replace said Distro with another.
Now, if that is not cryptic then I don’t know what is … 
Say what?
There are many non-native speakers around, hopefully they’ll have a better job understanding this statement (",)
To ‘replace’ Manjaro on, say ‘sda’ then you can simply install to ‘sda’.
If you install something to a partition with an exisiting partition, then it will be re-formatted.
Yes, simply boot with the other Linux’s live USB and install it over the same partition Manjaro is in.
Assuming you have three partitions in your disk:
/boot/efi - Boot efi
/ - root partition of Manjaro
[windows partition]
In the installation wizard simply select “Custom partitioning” option and set the existing /boot/efi and / as your new boot-efi and root partition respectively. It should replace Manjaro and set up a new Grub with your new Linux and Windows options.
