Question Windows won't boot from ssd

[Leronus]

Hey guys, just built my new computer.
I used the ssd from my ild computer which has windows & games on it. The computer turns on with all components running and boots into the BIOS automatically. It does so everytime though. The SSD is the only drive I have installed. It detects it as you can see in the image below, but it won't boot. Any suggestions?

If your motherboard has the option, change the bios to 'Legacy' or 'Legacy + Uefi' mode, and also enable CSM.

But don't be surprised if windows still won't boot. You have old drivers trying to run on the wrong hardware now.

Thanks for the reply,
I ended up doing a clean install of windows from a USB flash drive. Wasn't able to find the Legacy + Uefi mode, could only set it from Legacy to RAID or whatever, which pretty much caused the whole thing to crash lol. So yeah it did cause me to lose all my files but I didn't have anything useful on there anyways.
