After installing Zorin Os, no boot menu appears and boots into windows

So, I tried to install zorin os on a dualboot with windows 10, everything in the installation went well, there were on errors, except on some "file or directory does not exist somethingx25.plist" , but when I clicked restart now, it just booted into windows. When I tried the boot repair, it just gave me an error:
" The current session is in BIOS-compatibility mode ". But I already disabled CSM
and the only options to disable secure boot is "Windows" or "Other OS".

In your BIOS Settings, are you set to AHCI or to RAID?
Did you install Zorin OS as Legacy, though Windows is installed with EFI?

CMOS Was dead, so It didn't save the CSM option.
