ok
i tried UNetbootin and it did very well
i booted successfully
but i had another problem with my old GPU AMD radeon 7450
only complete boot with the option " safe graphics" other options make the monitor turn off with " no signal " message
even with safe grapgics options
i later have another message "
radeon error
and reolution is only 900*400
Are you able to take a screen picture without flash?
Did a websearch of "No UMS support in radeon module! Ubuntu" and found these:
Even after that error you can use your usb to boot , i tried it with ubuntu and it worked with no errors
thank your for your concern..
i read these topics well
but the problem here is i can't install the system
to make these changes..
even the safe graphics mode
the resolution is low
so the wizard is not completely shown
and i can't see or choose all options
From this screen, are you able to tap the e key in order to enter the grub editor? (Or... what happens if you tap tab?)
We need to try adding the grub parameter radeon.modeset=1 prior to you trying to boot Zorin OS.
thanx i tried
radeon.modeset=1
and radeon.modeset=0 also
both the same result monitor goes off no signal sign
i even tried to write the parameter without the line
but it didn't do anything it returns me to the grub menu
also tried the parameter
radeon.dpm=0
but same result

Do you have an intel integrated graphics card and a Radeon dedicated card?
Using nomodeset will fall the graphics back to the integrated card.
If the OS is not able to use the drivers for Radeon and it cannot fall back to the integrated card, nomodeset will not work.
However... I notice in your screenshot that you have Secure Boot enabled. That should be disabled in your BIOS settings.
this motherboard and CPU don't have integrated GPU.
just a dedicated GPU is used..
secure boot i couldn't find it in BIOS.. i think this MB doesn't have it
secure boot is greyed
this means it's not supported by bios
IF THI'S SUPPORTED IT'D BE RED OR GREEN
disabled or enabled

Sadly, in the past whenever I have encountered this type of "locking in" by a manufacturer, installing Linux in general has been very difficult, even "impossible" by the standards of the average user. Even Windows decreed that Secure Boot must be accessible to the user (Prior to Win 11. MS Windows now requires Secure Boot).
You may not be able to install Linux on this particular machine. They are built for Windows.
Even if you do get it installed, with only a Radeon Graphics driver, an update that has a regression in the AMD drivers could unexpectedly crash the build, leaving you in the same position you find yourself in now.
i already installed manjaro on this system
but i just want to try zorin
anyway
thank you all guys for your concern
but
don't you think this is strange as zorin says always
zorin lite is for old computers
Yes, it won't always halt the install. Secure Boot being enabled won't always be an issue.
Microsoft signed and validated many Ubuntu and other Distro packages in order for them to work with Secure Boot. But... MS did not sign them all. Which means that with Secure Boot enabled, some packages will work... and some will not. Usually confusing you when they fail.
I have installed Zorin OS and Zorin OS Lite on many old computers without any issues.
But nothing is ever guaranteed... If a manufacturer cut some corners in using cheaper hardware - or you are installing on an old Chrome Book or the computer has only a dedicated graphics card... Some computers resist Linux because they are built only for Windows.
ok thank you my friend for your time and effort
i may change this |GPU or change the whole computer
