Question Pc won’t boot to windows after upgrade

[Sweetsammiches]

I installed a new intel i9 9900k into my MSI z390 gaming motherboard and when I booted up it said it detected a new cpu then froze when trying to boot up when I restarted it said it was running a automatic repair and then keeps freezing

check your bios version and make sure it supports the 9900K, there are two Steppings - so 1 may require the later bios
