I dont have much time.Please send help asap.

OK, how did you create the USB? Did you format it first ot FAT32 file system? Can we have some specs of your machine please? Did you install manjaro using USB?

I formatted (erased all the usb) in gnome disk tool (or sth like that) then i writed iso file with isousb.I installed many os' with that usb (Ubuntu, Ubuntu Mate, Fedora, Antergos (was a bit tricky but i've been able to solve it) and Manjaro.)they didn't gave me any errors.But Zorin ... my computer ignores it.

Zorin OS is a bit different regarding the Live-USB. You have to format the USB stick as FAT32 and then use unetbootin to create the live stick.

Just creating the USB with DD as for Manjaro, etc. doesn't work!

unetbootin wont work for me.I tried it how do i format it as FAT 32 (im a linux newbie sorry)

Unetbootin says "Usb couldnt connect to the connection point ..."(It is Turkish im trying to translate)

wait it is now ... i just reinserted the usb after formatting ...

It is completed i will try it tomorrow ..

Hope it works i did what you said
1)Formatting usb with Gparted into FAT32 ---Done
2)Installing Unetbootin ---Done
3)Trying to write/burn the iso file but fail ---Done
4)Reinsert the usb and try again and success ---Done
**5** Try to boot ---Will do it tomorrow its too late now (In Turkey)
and hopefully i will get Zorin OS.

My preferred tool is MultiSystem and as you already have GNU/Linux distro installed I find it by far the best USB installer.

Good Luck!

The last point "reinsert the USB" is needed for Unetbootin to recognize the Device. Without reinsert the USB is not mounted after formatting.

Thank you very much guys.I finally installed Zorin Os 9 !
This is what i did :
1)Format the usb into FAT32
2)Install Unetbootin (Unetbootin will not work until its FAT32 [well mine didn't on other formats])
3)Write/Burn the Zorin .iso into you're usb with Unetbootin.
4)Restart you're computer and open the BIOS Menu.
5)Select you're usb and it should boot Zorin.
("Well if you're from Japan or Russia or etc. you should not select your Language in installation, or it will give you error.It must be English" i read this from a website i don't know if its true but i did it.Maybe it is true...)
