Changed mobo+CPU+RAM = SSD won't boot

[beeq]

Hey,

I changed motherboard, CPU and RAM, but decided to keep rest of the build untouched.
I ran into an issue, that the system won't boot from SSD, where I have Win10 installed. (Actually this was very expected issue anyway)

BIOS recognizes the correct amount of RAM, the CPU, and the SSD model (Samsung 850 EVO), but when I save and exit BIOS, computer restarts, and goes into the BIOS again.

The motherboard is ASUS Maximus VIII Hero, and it has a Q code display on it. The code usually stopping on 'b2' for a second, then lights up the (possibly) boot device led, and continues to BIOS, and then Q code display showing code '99'. Could this be just some UEFI / Secure Boot / Whatever issue?

The primary (and currently only) boot device is set to that SSD.

I know I shouldn't boot into that windows anyway, as it might not like the hw changes I've made, but currently I have no Windows CD/DVD, and I have lost my serial key for it.. So clean Windows install currently is not possible.

Basically I have some clue what to look for, but thought to give it a shot opening up here, if someone have had experiences on this sort of issue. It might be just a setting somewhere, a tag to be untagged, or vice versa..

Solution: I installed a new copy of windows (8.1) on that SSD, and everything have been working just fine with it \o/
