Ok, so I had some issues with a MB and just got the new one today... Now I'm having some crappy hard drive issues. I bought a case, 2 GB of Kingston RAM, 2.2 Ghz Brisbane dual core AMD processor, and now i have an MSI MB. I already had a CD drive and 80 GB HDD. Here goes the story... I put in the processor and ram, which I bought from Newegg and then I put in a cd drive that I already had and an 80 GB hard drive I already have with windows XP Pro installed. I tried to boot it up and it told me the NTLDR was missing, so it wouldn't let me. I messed around in BIOS and checked the hardware and what not, and it finds everything just fine and it's set up correctly, was running at 36C. So I put this hard drive back into the computer I am on now (I don't have two with a working OS on them) and it works fine on here. I tried to get the fix for the NTLDR thing and burn it on CD, but for some reason it won't burn (I used Alcohol 120%, as the file is an ISO.) I don't have a floppy, so I can't do that, so I'll borrow a jump drive from a friend tomorrow and try that version... Anyway, I found out that only way that XP Pro is working is when I have it as a slave with my 4 GB hard drive as the primary, which is how it was set up in this computer. The 4 GB hard drive is old and ghetto, but it had Windows 2000 on it, so I just put in the 80 GB, booted up 2000 and installed XP on the 80 GB drive and it worked to boot up just like that. I don't actually have an XP disc right now, so I can't do a new install, but I have Windows ME so out of curiosity I tried to install it on the 80 GB drive while it was in the new computer and it started to do some crap and then told me no and restarted... After it restarted, it tells me it can't install because of an error in the partition, so I tried to format the drive and it tells me I CAN'T format it. Something like, "program has caused a divide error" or something weird like that. So I put it back in this computer and it didn't work, I got a blue screen so I tried again in safe mode and then fixed it so it works again... I realized that for some reason, this drive only works as a slave with the 4 GB as a master (although it doesn't have Windows 2000 on it, since I started formatting it, but for some reason it never finished and left traces, so it still gives me the option of WIndows 2000 or XP at boot up.) Anyway, after I fixed XP, I put both hard drives in the new computer and it found the NTLDR this time and gave me the option to boot up Windows XP or Windows 2000, so I tried to boot up XP and it gave me the Blue Screen of Death... So I tried safe mode, and it still gave me the BSoD. I realize this whole situation is totally screwed up, but when I put the drives back in this computer it works fine. To be totally honest, I dunno what to do. I don't have money right now to go buy a new hard drive.
