Windows 10 boot issues

[UnrezolvedKaos]

I just installed several drives to add extra space (two 1tb hdds and 1 480 ssd) and now when I boot up I have to go into the bios and override boot from my main ssd. What is causing this and how can I fix it?

How are you overriding boot? Do you mean boot priority? Boot priority setting your os drive as first boot should stick.

Make sure that your boot load order is set correctly in the bios; if it is and this is occuring then you can try this: https://pureinfotech.com/repair-master-boot-record-mbr-windows-10/ . No need to download any files if you have your install disk; just just boot from the disk and run the commands in the repair/troubleshoot/advanced/command prompt from your disk.
