Hi all, i apologize if this is posted in the wrong place but i decided to reach out to this forum because i have no clue whats going wrong. Here's the situation: I switched from a 450w psu to a thermaltake 600w. It works fine and my computer is operational. The problem arises when i turn my comp on only to find that windows is not starting up. It tells me to insert a boot device and try again. I checked my bios (my mobo is an MSi Z97 gaming 5) and it clearly detects my hdd (a WD 1tb) and i have changed my boot priority to the hdd to no avail. Upon booting Windows 10 it wont even let me do a fresh install or re-format because my hdd is "locked". This has been driving me up a wall for days and any help would be appreciated! Thanks!
