problem booting after hard drive replacement?

It is probably simply a problem with the hard drive, like the computer says. Check to make sure that the connections are all good, and if this does not work, send it back for a replacement.

Reboot into safe mode... defrag then disc cleanup/repair. If you can get through all that and see that your harddrive has no bad sectors, then run virus scan. Some viruses connect themselves to the boot sector so wiping the harddrive doesn't get them.\n\nIf all is successful but you still have the problem, use your installation disc to either reinstall the operating system. I know you did this already but do it again after you have done all of the first part.

your harddrive has either failed, or needs reseating, if it is removable, take it out and put it back in, and try again, if you get the same message, it is time for the repair shop, unless you can change it yourself

Is the drive you are trying to format still the 'boot' disk?\n\nYou need to be booting on the new drive before you can format the 'old' disc.\n\n///

I think one of two things may have happened.  Either some of your system files got corrupted on the hard drive, which would be fixed with the restore disk.  Or you are having hardware problems that start when windows tries to talk to the hardware for the first time.  \n\nIf you know somebody that can loan you a windows install disk you might try it to see if windows will load.  If that works, the restore disk would probably install without any trouble, but if the same thing happens you might need a part replaced before you can run the restore disk.

may be your sestem boot from CD Rom or Floppy first of all you change the boot sequence from BIOS setup. Select the Hard Drive in First Boot.

need more info than that to diagnose.  make sure your cables are plugged in tightly?  is the jumpers on the hard drive on the correct pins?  can you hear it booting up. when does it stop?\ntoo many variables

1. Unplug all computer connections.\n2. Take off computer case.\n3. Find the cord going from your existing hard drive to the motherboard. There should be a free connection there somewhere.\n4. Plug in the new hard drive into that empty slot.\n5. You should see a 4 prong power cord coming from your existing hard drive. Find another one coming out of your power supply and plug it into your other hard drive.\n6. Screw in your new hard drive.\n7. Shut case and plug cables back in.\n8. Restart computer. Your computer should recognize the hard drive regardless of OS.\n\nPlease note that while these instructions work fine for installing hard drives on my computer, they might not work very well for yours. I'd get a second oppinion before you go tinkering w/ your computer if you've never done it before. Also, consult your computer manual for more detailed instructions.

Hmm think maybe you deleted an important sytem file like startup.ini or something. Asking for the disk means it wants a floppy. I would check the BIOS settings and make sure it is booting to the hard drive first, then try to start in safe mode by pressing f8 while it boots (if it gets that far) Otherwise sounds like you need to reinstall the operating . It probably wants a boot floppy, use one if you have one.

if this is a win 98 system . boot up in dos or with a boot disk get to the dos prompt type  get to the root directory and type Fdisk/MBR , might work not guarenteed . depends on damage .Oops a little more info. sorry had to go. but anyway after enter this command you will not see anysignificant activity . just reboot again...hopefully fdisk will have fixed the problem and you wont have to worry about file recovery.

ok set the go into the bios and change the boot sequence back to default, should be your cd rom drive most likely. You will need to load your windows disc in the cd rom and re istall. If you have back up disks (floppy) then set the boot sequence to boot from floppy and when prompted put the disk in. Disk boot failure is because there isn't a bootable disk in the drive is my best guess but no telling ehat all you have changed by now. If the system will not let you back in pull the plug and restart it go into the bios and set it to default settings for the boot seq.

Use Fdisk to delete the partition then Reinstall Windows. Doubt its a dead harddrive

its possible that your bios battery is dead and forgot what drive is in your computer, enter bios setup and have it autodetect hard drives.\nif the battery is dead the clock time will be wrong also, and all other bios settings.\nif you reset the clock and hard drive you will be able to boot one time.\nif this is the problem you need to replace the battery, it may cost you $2.\n\n\ngood luck\nTV

go to the hard drive manufacturer's web site and download their diagnostic utilities.\n\nOr you can download the ultimate boot CD for Windows and boot to that.  It has most manufacturer's diagnostic programs on that (but you need to burn the ISO image of the CD correctly.  Reference my sources below.

I can give you a link that deals with hard drive problems.\nSome hard drive problems can be easily fixed yourself by using easily available tools. I found the info at http://fixit.in useful

My opinion too. Hard drive is fried and your computer is trying to access the A: drive to find a boot program. Check you connections inside your computer and I mean all of them including reseating the power supply cable, hard drive cable, molex connector on all your hard drives and floppy drives. Try and reboot.\nIf all that fails, try and boot from your A: drive with a boot disc for your operating system or just reformat your hard drive and reinstall your operating system.\nSometimes it the simplest of things that cause problems. Start with the simpleist first and work your way to the harder ones.
