I was downloading zorin os then it failed so it restarted making my windows 10 bootloader to corrupt. I reinstalled windows then i go n disk managment to see a 80gb logical drive but i made a 80 gb drive in zorin os installer, it wont let me get rid of the drive and extend it to my c: so is there any way to fix it.
Welcome to the forum!
Do you have any screenshots you can give us to sort of go off of? If you reinstalled windows, I would've figured you would use the drive to go back to square one and start again, unless I'm misunderstanding?
That will help us to figure out what's going on a little bit better.

Ok, ill just send it soon
The logical drive is the one zorin os created during install but the install failed. I cant manage to extend my drive back to its orginal storage because it wont let me and the zorin os partition (the logical drive) was off my normal c:.

Can you clarify what is your goal? Delete that last partition, set up dual boot, ... ?
Out of the 4 partitions/volumes you see there, both of the last 2 are made by Zorin install.
Thus, you can delete both of them, then extend your 2nd (C:) partition.
a) graphically in Disk Management: right click on either of them, "Delete". If it's greyed-out, then try with the other volume/partition. If still so, proceed with the command line
b) command line. Open comand window (cmd.exe), type
diskpart
A new cmd window will open, for which you will need admin rights/password.
Caution! Proceed at your own responsibility!
Back-up important data.
If you type the wrong commands or ID in the commands below, you can end up with erased hard drive and you will need to re-install windows again.
list disk
see the number corresponding to your hard drive disk (based on size...)
Assuming it is N:
select disk N
list partition
It will list all partitionsyou have on the disk.
Based on your picture, you will likely see listed 5 (not 4) partitions, the extra one being called "extended" ( a virtual partition, as a containner for other, "logical" partitions), which contains the 80GB one.
Now, carefully, pay attention to the number (ID) of the partitions you want to delete.
If you decided to delete partition N:
select partition N
delete partition
If it says something like it cannot delete, then retry as:
delete partition override
To see the effect:
list partition
Then go back to Disk Management and check that the volume/partition now appears as "unallocated", black color.
In your case, you will need delete either 2 or 3 partitions, depending on whether the "extended" one will be delete automatically when you delete the partition inside it.
When done, in the "diskpart" cmd window:
exit
After you finish, in disk management you'll see just the first 2 windows partitions (original) then "unallocated" black space to the right.
Then you should be able to right click on your 2nd,main partition (C:) and select "Extend volume...". A wizzard will pop up guiding you.
If you need more references:
At "diskpart" prompt: ? lists all options

Hi and welcome.
I was a bit concerned about the location of the EFI partition as this is normally the firsf partition on a Windows installation. Before messing, I would backup all your data and take a look herev
I find it bizarre that Zorin OS should create an NTFS partition as it normally requires Ext4 FS to install to and wonder if this was caused by the USB installation software used to install Zorin. I would recommend that you use Ventoy over any other USB installation method, and when dual-booting, use Disk Management within Windows to shrink the C:\ partition first and install Zorin to the free space created.
I'm sure he wants to recover back to Windows and wants to extend his main Windows partition over the Zorin Partition.
I've encountered this issue a lot of times so I can understand this issue 
In conclusion, delete the Zorin partition and extend the windows partition.
By the way @klm, did you Delete (or Erase option) all the partitions till it got combined into one huge partition when you were installing Windows? If that wasn't possible, then fixing this issue would take a bit more time.
If you can try reinstalling Windows again, you can check this tip out!

On the logical drive I only get shrink and delete and I delete it but still can't extend my c drive
Delete the last partition.
That's the thing I can't extend it even deleting the zorin os partition to unallocated won't let me
If need I can record a whole installations n of windows
That's on a UEFI /GPT based disk, not MBR/ legacy BIOS based one.
I'm pretty sure @klm has the latter, from my own experience recently installing (dual boot too, then reinstalling Windows too) on MBR disk, and based on these 2 microsoft references:
@klm , you cannot extend the C: partition until you only have "Unallocated" free space immediately on the right of it.
So you need to delete the 3rd partition as well.
One reason it may not allow you to do it in Disk Management right-click options is that it is marked as "Active". Try to unmark it and mark only the Ist partition as "Active" then try to delete 3rd again.
If still not, then you have my cmd.exe "diskpart" instructions above.

unallocated dosent work and the cmd one dosent either i can boot into zorin os installer and see if i can fix it from there
If you show us exactly what you tried and didn't work, perhaps we'll be able to make it work.
By the way, my install of Zorin also didn't work the first time; eventually, it installed and works fine...

Yes, that doesn't wok because between Your C Partition and the Free space, You have the EFI Partition. To expand Your C Partition the free Place have to be directly beneath the C Partition.
