Windows 10: Asus Laptop Q325UA Secure Boot Violation

Hi everyone I'm having a secure boot violation issue with my Asus Q325UA machine, which is just over a year old.


Its CPU Intel Core i7 8550U 20

SSD 512 GB

Ram 16GB


was running the unit as normal and left it on overnight and restarted the next morning. Upon restart the following message was displayed

"Secure Boot Violation

Invalid Signature Detected Check Secure Boot Policy in Setup"


So i was able to enter asus bios setting and disable the secure boot feature, click save and restart.

When booting back up, the unit gets stuck on the Asus Logo Startup screen and nothing else happens.


Went back into bios and disabled the cdm option and again the same thing happened on restart - frozen on asus logo Startup screen


There are no other options i can find in the asus bios version 308 that would allow me to get at the UFEI option and get into windows. Even creating a bootable windows usb drive and using that gets me to the asus logo startup screen and I see a circle spinning under the logo and then the screen just goes dark and nothing else happens. I can't get into windows environment at all


Took it to a friend of mine who removed the ssd to mount it externally and it shows the ssd is bitlocker encrypted. Now i bought the machine from bestbuy as an open box item, and upon using it, I never saw anything pertaining to a bitlocker key or even an option to turn on bitlocker. All i can speculate is that previous owner turned on bitlocker and bestbuy didnt wipe the system properly and i am now stuck without any keys nor can i get into windows to attempt to do anything.


I dont want to wipe the hardrive as I'm a student that has impt files on there ( and no I didn't have a image backup--my fault) Anyway I would greatly appreciate any insight someone may be able to offer on this matter.


Thanks

:)

Can't access BIOS Secure Boot Violation

Nothing worked, I'm having issues with running windows 7 probably because I can't get into bios to change bios to be friendly with windows 7. Secure boot should still be enabled but I do have CSM enabled. I had to wipe windows 7 and reinstall windows 10 to get past the secure boot violation and boot up.

 

secure boot violation

My laptop had a critical update which was downloaded automatically.

I asked it to restart after installing the update.

After the "MSI" welcome screen a message came up saying"

Secure Boot Violation

Invalid signature detected. Check Secure Boot Policy in Setup

It is the first time I received this message and can't make out what i should be doing.

Any help would be appreciated.
