To put in a nutshell: Try to disable Secure Boot:

• How can I check in Windows if Windows is installed in UEFI mode with Secure Boot ?
• How can I change UEFI firmware settings from Windows ?

Long version: If Secure Boot is enabled (default value of Windows 8, 10, 11,...), it is necessary that all boot loaders and system drivers are signed.

1. Wubiuefi has signed its boot loaders with a MOK (see here).
2. Ubuntu has signed its default kernel and drivers on ISO image with keys which are verified by Microsoft.
3. But some individual systems drivers should be signed during installation with a key that is generated for your device.

Probably, the signing of individual system drivers do not work.

Thanks for Contributing for the issue,

I checked and i got result like these

I have already UEFI mode and Secure mode is disabled

But i m using Zorin OS via doing some tweak
1. I press F12 for Boot Menu
2. Select Wubiueif , rather than windows Boot Manager
3.

Then Zorin OS loads from there and this is working so good, and i have to do this every time when i need to switch in ZorinOS but some problem, i will explain this problem at last

Reason for works after this integrity: Problem Loading X.509 Certificate -65 Error on Finishing installation of Ububu 22.04 or Zorin OS 16.2_, is
let suppose i manally reboot at time t=0,
and installation will start at t=30sec,
and after time t=15min installation is finished,
and at that time PC is going to reboot by self, and then ERROR come. But keep in mind that Installation is Complete, means all files are present in Wubi Created virtual Partition

Some Problem that i m facing with Zorin OS now, it is off-topic as per the issue, but if These anyone have Solution then please Comment
Note: I m using Zorin OS 16.2 Pro and My System is up-to-date

1. I m unable to fire CTRL + S, CTRL + K, CTRL + M, I m 100% sure that My Keys are working, because in Windows they are working perfectly fine
2. I got Console Screen with some text (Background logs of Kernal like stuff), when i try to put in Long time sleep, or sometime it appear for manually Sleep via power button, Unable to write command in the Screen at that time, No GUI or Something, it is Pure Console with White text and Black Screen, I unable to Get my GUI screen, i final Option left is from manually Shut donw from the long press of power button
3. Sometimes Touch pad is not reacting well as it working cool in Windows, or Sometime i feel it lags

I am glad that you solved the originally reported issue. To be honest, I misunderstood your report. I thought it was a boot issue, but now it sounds like the known issue on reboot from e,g. r345

Known issues:

• Manual reboot is necessary after second part of installation.

There are often other non-fatal errors displayed. But the issue is only that the shutdown part of the reboot does not work automatically.

But i m using Zorin OS via doing some tweak

1. I press F12 for Boot Menu
2. Select Wubiueif , rather than windows Boot Manager

It is similar to "Where is my Ubuntu entry in Windows Boot Manager for UEFI ?"

My Problem about ZorinOS get solved, if anyone got same type of issue please you can solve using this

1. I m unable to fire **CTRL + S**, **CTRL + K**, **CTRL + M**, I m 100% sure that My Keys are working, because in Windows they are working perfectly fine

Solution: These combination not working because i set key combination in Zorin Connect but They are working Globally, thats why they prevent to fire these combination, after removing the combination shortcut , i am able to fire these combination again

2. I got Console Screen with some text (Background logs of Kernal like stuff), when i try to put in Long time sleep, or sometime it appear for manually Sleep via power button, Unable to write command in the Screen at that time, No GUI or Something, it is Pure Console with White text and Black Screen, I unable to Get my GUI screen, i final Option left is from manually Shut donw from the long press of power button

Solution: I recently installed the NVIDIA Driver for my GPU and after unistalling the driver my issue is gone

3. Sometimes Touch pad is not reacting well as it working cool in Windows, or Sometime i feel it lags

Solution: Due to GPU cursor stucked sometimes, now it is pefectly fine
