i tried using a recovery disc but to no avail. it displayed 'Reboot and select proper boot device. or insert boot media in selected boot device and press a key'
So i went to download winsetupforusb and reformatted my thumbdrive and did everything as per instructions. But when i attempted to boot into the thumbdrive. All the monitor showed me was a "_" key that was blinking. i decided to let my computer do its thing (for around 8hours). but the screen stayed the same.
(the usb is working as i've tried to boot from it from my laptop) i also noticed that during the startup sequence, there wasn't a hard drive that was detected.
so today, i bought a 1tb hdd but the same thing happened.(for both the thumbdrive and the cd drive, but my new hdd was detected though)
So i'm wondering what might the cause be.
