Changed cpu, Crashes kn boot

[Liniz00]

Yesterday I changed my cpu from a i5-9400F to a i5-9600K and suddenly my computer wont boot, and it says it’s missing winboot.efi, anyone knows why?

Head into BIOS and change the boot priority. It probably reset the BIOS settings and changed the boot drive to another one.

When i select the SSD where I have windows installed it just says “Reboot and Select proper boot device”

Go to bios and choose proper boot method. UEFI or legacy, depends on how your installation was made.

Select "UEFI only" at first then try.

If you want to choose boot order in case UEFI+Legacy mode, use "Windows Boot Loader" as priority drive, not just drive where your system is located (because UEFI+Legacy boot in bios will show you your devices both - as possible to boot in Legacy or UEFI mode, and you probably selected Legacy mode device).

 

Sorry for not so great explanation, but I hope you'll change it proper.

We can say for sure its a UEFI installation as its using the EFI Boot Loader.

If the above instructions don't work boot from your installation media, click Repair My Computer then select Boot Repair and see if Windows will repair it or not. If not then its BCD editing which in my experience rarely works.

Ay, that is a head ache and needs reading and understanding a lot of commands in command line. But it does work.

Easier (and probably faster)  would be doing an automated repair or refresh-install, keeping settings and files if it is possible, of course.

Repair Windows or reinstall or anything like that is not necessary - especially when OP only replace processor. Accidentally resetting BIOS settings is what happend (95%). Some BIOS-es gives option like "load default settings" in case something was changed in hardware. If OP do not skip that but choose that option - the only he should do is to proper re-configure BIOS.

It turned out the 9600k where broken from store. It wouldn't even go into bios when they tested it in the store
