Recently, some friends have consulted the editor about what to do if a blue screen appears after the Phoenix system is restarted. The following is a specific method for everyone to deal with a blue screen after the Phoenix system is restarted. Friends in need can come and learn more.
Some UEFI-booted users have a blue screen prompt after installing the Phoenix system and restarting: Verification failed: (15) Access Denied, enter Windows directly after pressing Enter and cannot enter the Phoenix system.
This is caused by Secure Boot being turned on in Bios. Just enter Bios to turn it off.
What is Secure Boot?
Secure Boot is a sub-rule of UEFI, its function is to prevent malware from intruding. The implementation method is to build in some paid public keys when the motherboard leaves the factory. Any operating system or hardware driver that wants to be loaded on this motherboard must be authenticated by these public keys, otherwise the motherboard refuses to load.
But UEFI does not stipulate which public keys are reliable, nor does it stipulate who is responsible for issuing these public keys, leaving it to the hardware manufacturers to decide. Microsoft forces motherboard manufacturers to build in the Windows public key, which means that operating systems that have not paid Microsoft cannot run without turning off SecureBoot.
How to turn off Secure Boot?
You only need to enter Bios when booting up and turn off Secure Boot (set it to "Disabled")
Different manufacturers have different BIOS styles. For details, you can consult Baidu or contact the customer service of the respective device.
The above is all about what to do if a blue screen appears after restarting the Phoenix system. I hope it can be helpful to everyone!
