I’m having a bit of a problem. Could you give me a help?

The first time I discovered Zorin OS was about two years ago, and honestly, I loved the experience. It felt smooth, clean, and just really enjoyable to use.
For some reason I removed it back then, but now I genuinely miss it and want to come back to it again.

Right now I’m stuck with a modified version of Windows 11 on my system:
OS: Windows 11 Ghost Spectre
RAM: 4GB DDR3
Processor: 1st‑gen Intel Core i5 vPro
Graphics card: AMD Radeon HD 6450
Storage: A One hard drive 1TB HHD

To be completely honest, these modified Windows builds have been giving me a lot of trouble.
I’ve been dealing with random issues, weird bugs, and constant headaches — and I’m honestly exhausted from all of it.
That’s a big part of why I’m really looking forward to switching back to Zorin OS.
I’d love to install Zorin OS alongside Windows this time.
Last time, when I removed Zorin OS, my Windows installation got messed up, and I really don’t want to go through that again.
I just want to set everything up safely, smoothly, and without losing Windows at all.
Thank you so much to the wonderful Zorin OS support team — I truly appreciate your help and the work you do!

As a quick start:

Zorin OS and Windows OS will be (and must be) installed on separate partitions.
From the computer's perspective, this is like them being on different planets.

So the element of risk in this would be the EFI partition, where bootloader files are shared.

Since you are using a debloated Ghost Spectre copy of WIndows, this does introduce uncertain variables - including what the modifications are to their Bootloader.

First, make a BackUp of your Windows Drive data and installation.

You can use this thread to reference if you get any errors by stopping activity and relaying the error here before continuing.

or proton?
i just using wine for it.
just stable version

The EFI boot partition would be located on one of the hard drives.
It appears, based on your comment, that it was located on the hard drive you had Zorin OS on, which meant that when you tried to boot Windows OS, the bootloader was not found.

Plugging the drive back in should have restored that ability.

Yes, you can install on separate hard drives. There is no need to unplug one. Leave both plugged in, and boot the Zorin OS LiveUSB stick.
From the Install wizard, do not select to Install Alongside Windows OS.
Instead, select to Manually choose where to install.

This will open a partition manager.
From the drop down menu arrow for the drives - select the drive you want to install Zorin OS on.
In GnuLinux, drive Identifers are shown logically, instead of how Windows labels them as a;, b;, c; - so feel free to post screenshots to confirm Driver Identifiers.
