During the instalasion on win xp,wen setup is starting windows there is blue screen appers with that words ''unknown hardware error''

hello,

• Turn off the laptop.
• Unplug from power if connected
  
• Disconnect the hard disk power supply and re-connect after a while.
• Now start the PC and run set up.

thanks!

This because you dont have AHCI drivers required for Win XP and you set in BIOS either sata controller or ide controller to an AHCI. You must set to native IDE or anything else like that.
If you wish set an AHCI driver you must press F6 during starting windows XP setup. And put the drivers (get it here) to floppy disk, it will prompted to install required drivers..
Another way to install driver without floppy disk you must inject the driver to windows XP installation CD...

P.S : you cant put the drivers onto floppy, because it wont be read by Windows XP setup..

If you get a blue screen then you have a piece of hardware loose inside your lappy or could be a loose cable on the hard drive or cd/dvd rom, since lappy's are very hard to take apart it's best to take it to a shop to get fixed sorry.

your windows operating system is probably corrupt you cannot recover all of your files,
unless you have an file recovery software.
re format your disk c and put an operating system again.

Hi jenishrabadi, Have you tried using different source software for your windows xp installation.
There should be an error code when you receive the blue screen. post the code here, it may seem like 1) either corrupt software or 2 ) Faulty hardware. Most likely memory.
without further performing any more diagnostics (as we do not know what the actual error is) and making the assumption it is faulty hardware, if you have more then one memory cards in your notebook, try and take one memory card, then try the setup/install. if this fails .. put the memory card back in, and remove the 2nd memory card and try again.
good luck ... hope this helps ...

is ther an error above this code like DRIVER_MISMATCH? or some words of this kind? Thanks Mark ;-)

Have you added any new hardware or updated some drivers? You may need to go into safe mode.

try to change harddisk flat cable..

Have you installed new hardware recently? if yes, try to remove it again.

other option is to boot up using your windows xp cd, choose the rescue console, and type "chkdsk c: /f" ( without the quotes)

if that still doestn fixes it, you boot again using the cd, and then choose repair installation. let it do its thing. It will reboot when done.

can you adjust buffer size in config please try this
