Advice on how to get out of a boot loop on my Windows 10 PC?

[MnMWizard]

I'll try to make this as easy AP to read:

- We have an office PC with Windows 10 (has 3 1TB hard drives in RAID 5, don't think that matters though).

- I have a USB that is able to boot a full copy of Windows 10

- I forgot I left the USB in the PC, and in the morning my dad tried to use it, and asked why the computer was saying log into a different username (it booted from the USB rather than the RAID array). I took it out and turned off the PC.

- Now the computer gets stuck in a loop of: power on > gets to blue windows on black screen to load windows > BSODs and collects error info > I choose restart in the following options screen > repeat.

Any advice? Did something bad happen to the RAID array? Thanks!

1. Reset CMOS

2. Boot to BIOS and look at array

Sorry for being a noob, but would that not corrupt the array? It's a h97 board with raid support, and I'm not the one who set it up. Just want to make sure I'm not going to screw anything up by taking out the little battery because we have some pictures on it that we didn't back up recently.
