How to fix if NT-Loader is missing?

Hello there!
I am having a problem with my computer and I am hoping you could lend me a hand. You see, I formatted my Acer Aspire 5670. After I finished formatting and turned on the computer, I saw an error message saying “ntldr is missing”.
I tried looking for answers online but I still could not figure it out. I tried restarting my computer and then I pressed F2.
When I did, a menu saying Phoenix Bios Setup Utility flashed on the screen, of which I don’t understand anything about.
I hope you can help me figure this out. Thank you.
