There may just be a god afterall!
OK so after the installment of my sister's old hdd didn't work, I decided to try using my dad's (which is a Maxtor 80GB IDE hdd, a bit better than the quantum lol). Now at first I was kinda getting the same problem. I would boot up and then this time it would actually get to the windows loading screen, but then it would just restart without the blue screen, so I'm pretty pissed. I try it again though, and this time it asks how I wanna start windows since there was just an error obivously and I choose safe mode, well what do you know, this works! So I'm in safe mode and I go to the computer management thing and what not and choose to format the messed up seagate and voila, it's currently reformatting! Now all I gotta do is sit and wait for it to finish and hope that all goes well and then I'll be set. But then again knowing my luck with this computer of mine I'm sure something is bound to show up, but for now, I'm a happy man! Thanks everyone!
EDIT: I'm using my sister's comp to post this BTW. You can never have too many comps.
EDIT 2: Well just as I said above, something showed up. I set the boot priority to read my cd rom first with the windows xp disc in and it still wouldn't read it, instead it skipped along to my hdd and even when it did, it said NTLDR missing, press ctrl+alt+dlt to restart. Now I'm hoping that's just cuz I don't have an OS on it yet, but if it's a general hdd problem then wtffff? And the thing that's pissing me off most now is why my cd rom won't boot. I even switched my cd rom to the primary IDE master (it was the second previously) and it still won't do it. Then I even FORCED it to boot from the cd rom (set everything in the boot priority to cd rom) and then it gave me a message saying disk boot failure, enter the system disc and then press enter, even though it was already in, and then when I took it out and put it back in and pressed enter, it still wouldn't work. WTF? This makes no sense. Can anyone help me out???
