Solve : Laptop OS fails to load?

Answer» <html><body><p>I'm trying to fix a Lenovo 3000 N200 Model 0769 with a pentium dual core processor, a WD 160Gb #WD1600BEVS-08RS hard drive, and 2Gb RAM <a href="https://interviewquestions.tuteehub.com/tag/running-1192206" style="font-weight:bold;" target="_blank" title="Click to know more about RUNNING">RUNNING</a> Windows XP sp3 Home.  Could not find the restore CD, but have a copy of the OS on CD.<br/><br/>A few months ago, the system crashed while I was using the computer and would begin this endless loop of trying to restart windows and then failing.  I suspected a failing HD, so I tried to put the drive into an external enclosure and plug it into my desktop PC.  It was not seeing the drive, so I bought a tested one (same model) from the internet.  Later, I was <a href="https://interviewquestions.tuteehub.com/tag/successful-1231881" style="font-weight:bold;" target="_blank" title="Click to know more about SUCCESSFUL">SUCCESSFUL</a> in bringing the OS back up again and immediately began copying files to a backup drive.  Every so often, while copying image and video files, the OS would crash again and I'd restart successfully. I suspected corrupt files or bad HD sectors.  <a href="https://interviewquestions.tuteehub.com/tag/eventually-976663" style="font-weight:bold;" target="_blank" title="Click to know more about EVENTUALLY">EVENTUALLY</a>, it quit loading Windows altogether.  I received the purchased replacement drive, however, when I plugged it into the laptop, it didn't seem to find it and I guessed that it had not been formatted yet.<br/><br/>I took it into work where we publish a software database and plugged it into the Windows 7's mother board SATA plug and successfully detected and formatted the new drive.  I also plugged in the "failing" drive, which it detected  and ran a scan on it, <a href="https://interviewquestions.tuteehub.com/tag/automatically-2451134" style="font-weight:bold;" target="_blank" title="Click to know more about AUTOMATICALLY">AUTOMATICALLY</a> detecting and fixing any bad sectors.  It seemed to complete successfully and when I plugged the drive back into it's laptop bay, the OS loaded fine.  I resumed backing up the rest of my files and continued using the computer for about another month.  The problem has since reoccurred.  It would simply crash.  Upon restart, I get the following blue screen error <a href="https://interviewquestions.tuteehub.com/tag/message-25597" style="font-weight:bold;" target="_blank" title="Click to know more about MESSAGE">MESSAGE</a>:<br/>A problem has been detected and windows has been shut down to prevent damage to your computer<br/>UNMOUNTABLE_BOOT_VOLUME<br/><br/>This message flashed so fast, I had to take a video and stop it at the exact moment to read it.<br/><br/>And after a few attempts to reload windows in the last known good config I got this one:<br/><br/>A problem has been detected and windows has been shut down to prevent damage to your computer<br/>A process or thread crucial to system operation has unexpectedly exited or been terminated<br/>...<br/><br/>Technical information:<br/>*** STOP: 0x000000F4 (0x00000003, 0x8933F020, 0x8933F194, 0x0805237A8)<br/><br/>I've not recently installed any new programs.  I was running Avast and have had no recent virus activity that I was aware of.  The only new hardware I added was several months ago when I spilled a bit of beer on the keys and had to buy a new keyboard for it, however, while the keyboard wasn't functional I simply plugged in an external one and everything was fine until this recent crashing issue.<br/><br/>I've tried starting the OS normally, in all of the safe modes, and with the last known good config and none worked.  Then I tried to install the new hard drive and install Windows fresh onto it, but I get a message saying that no hard disk drive was detected.  I returned the old drive and was successful at getting a Reatogo boot CD to run its CD-based OS and was able to start a new task through the Task Manager and ran a command prompt window.  I was able to read the old drive's directory via DOS.  I couldn't seem to get chkdsk /r to do anything...I'd type it, hit enter, and it just entered to the next line and sat there doing nothing.  I also tried fixboot, again with the same result.<br/><br/>Any help I can get would be very much appreciated.Sometimes the Win error messages loop a few times.<br/>Put the new HDD in and do a few cold boots...then change the boot order to CD 1st...put the Win OS CD in and re-boot.Put in new drive, and turned power on.  Power light comes on, fan cycles up, hard disk light comes on for a few seconds then goes off and nothing else happens.  Power light stays on though.Then you're 1/2 way there...<br/>Now put the Win CD in...set the BIOS to boot to CD 1st and re-boot.Thanks patio.  The reason my laptop couldn't find my hard drive was simply that the new hard drive wasn't set as IDE!  Case closed...windows installed!     Cool Beans...<br/>Good sticktoitiveness on your part.</p></body></html>
