The disk is MBR. That is another issue in itself (as I mentioned previously). You can change a primary partition to a logical partition (like the data partition) without losing data.
When you format a partition, you erase the area that indicated what all was in that partition. The data still exists, but you need special software to recover the table that held all the information for that partition and it will take a long time, even with a fast computer.
There is no undo once you click the green check apply button. If you didn't, and closed the window it did not write the operation (Linux gparted acts this way, windows disk manager does not). Close out gparted and reopen it... it shouldn't have changed, if this is the application you used to make that change.
In gparted, nothing actually changes until you hit the green check (apply button).
On any of the partitions that don't contain bootable info, say sda4, you can click it's name, click the cog, expand flags and uncheck boot.
After each change I recommend applying that change. This will help ensure that each modification happens as it should and you don't get ahead of yourself.
Where do you want the 83GB of unallocated? Is that too be added to your Linux partition, Linux data partition... it will matter where it is depending on what you plan for it.
Moving space and partitions is difficult and should be determined now before you do anything else.
This is because your risk is set to MBR and all of the primary (bootable) partitions are consumed. The data partition doesn't need to be bootable, so remove that flag as I outlined above and you'll get the option. This will most likely only use the unallocated 83gb though. Use something else as outlined in Partition & Install but not before performing Before You Install
Isn't it necessary to convert from MBR to GPT, since after searching it turned out that Linux is not compatible and will not work properly and the possibility of losing everything with MBR, not to mention that the Windows 10 version
Since it took 4 days to complete the system installation and the delay in response and the inability to wait due to the need to use the device, I had to make efforts while being careful not to mess around and I failed to pass this step
If you set the partition to mount on system, your home and swap would be a part of that unless otherwise specified. It you attempted to install without changing the disk from MBR to GPT, if may not see the device to write to it. You may need to either convert or turn on legacy mode in bios. If you don't complete the Before You Install, prior to attempting to install, it may not work either.
I outlined in a previous post to remove the boot flag, which is what differentiates from primary and logical. You can also do this in windows, without losing data, i believe (it's been a while since I've done it). In gparted, select the partition you are changing, select the cog, options and flags. Uncheck boot.
The Windows system is on the disk and I see it, but it is defective and does not work, and I cannot run it due to a defect that does not need to be mentioned, and for fear of waiting too long, so I decided to ignore it and go ahead and install Zorin in an empty space knowing that Windows does not boot, whether it is booting from a portable flash Or a hard drive, because the machine doesn't support UEFI running the default Ventuy because it doesn't see Windows during boot so I can disable fastboot or hibernate
Use the something else method to install. Choose the partition and set the mount to /. Overwrite the windows boot manager partition (900mb) with grub 2. This should resolve your issue.
If you chose alongside windows, it would have created a partition, doing the same thing, but maybe not as you had expected.
Make sure one of the other partitions, at least, is changed to logical or it won't work.
You know that I use a compiler, and I can understand the theories clearly only through practical applications, and that is step by step, for example, distinguishing the basic disk from the logical one or converting it, and to avoid this problem, just diagnose the problem, mention it, and let me find the solution
I cannot do without one of the four main sections that contain Windows and my things, I am afraid that the mentioned section will be important when I try to repair Windows
