Question Mobo not booting after converting ssd to Gbt from Mbr.

[15YrOldCaptain]

Okay so I did something really dumb and converted my sdd to gpt from mbr with easeUS when my motherboard only supports legacy bios (I think). Its a lexar SSD and the pc is dell precision t3500. That was my only drive and had my data and windows. Now my mobo does recognize the ssd but once I boot nothing happens and if I press any key the pc beeps.
Help please ;(. TIA

Were you using UEFI BIOS prior to converting the drive to GPT?

Nope. And I dont think I can since I cant find the option in my bios anywhere to boot an UEFI device. My ssd was mbr before.
