Reboot and select proper boot device. Harddrive or something not so bad, or something far worse?
I Have a Asus-G73jh rbbx05, Im wondering if there is any hope?
I have had a lot of problems in the past months.

my battery died 1 year ago, i have no plans on buying a new one.

My computer sometimes wont turn on if it gets unpluged accidentally or power goes out, So i have to unplug power cord from the wall then plug it back in after 1 minute and it starts up fine.

About 1 month ago my computer froze with google chrome, i guess bitdefender was updating, My computer Blue Screened and then i first received this reboot and select proper boot drive. i googled around and found to f2 and load defaults and that fixed this problem, i blue screened on startup twice, then it loaded up fast and fine. i tried to do a chkdsk 1st time it said i had a bunch of unreadable files and comp powered off after 25 min, 2nd time bunch of errors and computer and comp powered of after 25 min, 3rd time worked (put a fan on my computer since this laptop overheats in safemode/ect.) it fixed a couple errors i defraged (19%)
Computer was fine it blue screened a couple times b4 the 3rd chkdsk worked, also bitdefender got corrupted i guess wouldnt install or uninstall and cntrl alt delete would blue screen me, i never tried to cntrl alt delete or mess with bitdefender since 3rd chkdsk.

anyway it was working fine faster than before, i was even playing aion max graphics while watching twitch.tv in the background np.

then all of the sudden while watching some tv on my comp, it partally froze when i alt tabbed it showed all 3 of my open tabs in those 3 little windows and the video was playing fine but the start bar was unresponsive. so after a couple minutes i held the power button and shut it off.

Then i got "reboot and select proper boot device" i tried the load defaults but that didnt help.

i know its too be expected for HD it to die after 4 years of 4-12 hours a day.

anyway is it 100% my harddrive and a simple replacement will have my comp running fine again, or something else.
If it is the HD would this be a good one/place to buy one

i was planning on building a desktop for like 3-4k in 5 months after im done moving around and i want to use this laptop for college purposes only at that point. So i dont want to spend more than 100$ on a HD.

Im not the most computer savy person, just a fyi. and thank you for your time.
