hello guys so after i installed zorin and tried to do the restart to boot up into zorin it shows me
Minimal Bash-like line editing is supported for the first word TAB lists possible command completions anwhere else TAB lists possible device or file completions
i followed guides on videos but it did not help what can i do in that case and when i try to boot into the boot loader my USB stick isn't shown on the list
You might want to go into the BIOS and make sure that you have options such as Fastboot or Secureboot disabled. From there, you should also be able to determine the boot order so that your USB is selected first, and even select it manually as the target.
once everything is installed and the system told me to restart i did click restart but instead of booting up and showing zorin Logo booting up that GRUB error showed instead
If you're only planning on using this computer for Zorin OS, I think it'd be better to let the installer deal with the partitions. You can do this by selecting the "Erase disk and install Zorin OS" option when asked about the installation type.
As a precaution, you might want to also check the integrity of the downloaded ISO file to ensure that there is nothing wrong with it (in case it got corrupted during the download, for example).
These articles might come in handy if you need some reference material:
the thing is that i don't really want to make a complete fresh install since i have a personal data stored in a partition with a big enough storage for it and i don't really have any other device to back it up
That's a dangerous game you're playing, then. All drives fail, eventually. I highly suggest you get your hands on one as soon as possible, if nothing else to keep your personal data safe. It would also have the nice side effect of solving your problem with the installation... which you might want to hold off until you can solve this problem first.
With that said, try to boot into the live USB where you have the Zorin OS ISO and take a screenshot of your drive layout as shown by the Disks application.
For reference, you can follow a schema similar as I described in this post below. The main difference is that I'm using the entire drive (you would only use the 200GB partition) and I'm also adding a /home partition, which you can omit if you want. As for the swap space, you don't really need it and in fact it might actually contribute to wearing down your only drive quicker, so you might actually want to disable it altogether (there's also a swapfile created automatically that effectively works in the same way).

I know you said that you made a partition for your boot, but when you were installing there should be a dropdown at the bottom of the window to select where to install Grub to. Did you tell grub to install specifically to that partition, or did you leave it (or not notice it, it's honestly fairly easy to miss) to the drive itself, which could lead to a situation like you're running into now.
no i did not get any drop down notification after the install i just found that it tells me that the installation is sucessfull once i rebooted it got stuck in that Black screen Grub error instead
tbh i just did not notice it at all since i was just letting the installation process finish so i wasn't really keeping track of anything while the system deploys it's files
