isapnp file corrupt!! HELP :)

Hey there. I'm a newbie in the middle of a rutt right now.

When I boot my computer I get an error that says:

Windows could not star because the following file is missing or corrupt: System32\DRIVERS\isapnp.sys

You can attempt to repair this file by starting windows Steup using the original Setup CD-ROM. Select 'r' at the first screen to start repair.

My problem that I am having is when I press R at the first screen, it just takes me back to the original error message. I do not think I am having hardware issues because everything is pretty much new and my computer has been sitting for a while and has not been used because I have been away.

Can anyone offer some advice? Anything would be greatly appreciated!

Thanks!

Take a breath

What OS are you running...xP/2000/98 etc

Can you boot into safe mode??? Hit F8 while starting up...before windows loads

Are you on a network???

Google seems to have alot of info on this

Are you sure it is set to boot from the cdrom drive?
:cool:

Looks like you need a service pack...

More info is needed

As rcgreen has said are you sure you are loading from the cd???

Taking a breath...

I'm running windows XP Professional. I cannot even get to my windows start up screen. It runs through my start up screens and right before it gets to my windows screen I get that errow message about my isapnp.

I finally got it to the screen so that I could try to repair it from my cd rom, and it says that: setup did not find any hard disk drives installed in your computer.

I think my bios are screwed up, but I'm not exactly sure what could be wrong with them.

I am on a network with one other PC. I run a wireless network for my 2 pcs off of a main computer.

Thanks guys :)

How about safe mode???


doesnt make sense...boots to windows loading..then cant find hardrive....

Sounds like your hardrive might be going...

Try and run chkdsk

Been able to fix things using this....although you may want to consider a new harddrive soon ;)

It won't let me boot into safe mode.

I have 2 seperate hard drives that are connected. Each one is 280gb. I highly doubt that they could be bad, but I could be mistaken. I've tried to remotely repair the file from my main computer, and due to the wireless network, it will not allow it.

I will try running the check disc :) Thanks

Well you will need to get into the recovery console to run chkdsk

so I would double check your BIOS settings and make sure you are booting to cd first

MLF

In my Bios this is my options:

My first option is
1)SM-WSM-522
2) FT TX ARY 1

Not sure which one is which. But thats what it is set up as

Sorry..but I have no idea.....

I usually hit del or what ever the flash on the screen asks for to enter setup...then I go to boot sequence..and set there...

every bios is different....

so you may have to go through a few screens......

if this is not your expertise...I would get help....

Your options should be

disk 0
disk 1
cdr or optical device
floppy

Make sure cdr or optical device is selected

MLF

Eh, I've tried starting them from both at this point, and it still continues to go back to the same error code. I have no idea at this point!

I've tried everything at this point! I think my hard drives could be bad!

Personally...I think your bios is misconfigured..........

So before going on to that.....lets establish...

Can you boot from cd???

MLF

If you can boot from your CD:

Isapnp.sys file is missing or corrupt
Windows could not start because the following file is missing or corrupt:
\windows\System32\Drivers\Isapnp.sys

RESOLUTION

To resolve this issue, use Recovery Console to replace the Isapnp.sys file.

To replace the Isapnp.sys file in Windows XP, follow these steps:

1. Start the computer from the Windows XP CD-ROM.

2. At the Welcome to Setup screen, press R to repair, and then press C to start Recovery Console.

3. At the C:\Windows prompt, type the following command, and then press ENTER:

ren c:windows\system32\drivers\isapnp.sys isapnp.old

4. At the C:\Windows prompt, type the following command, and then press ENTER:

expand cd-romdrive:\i386\isapnp.sy_ c:\windows\system32\drivers\isapnp.sys

For example, type:
expand d:\i386\isapnp.sy_ c:\windows\system32\drivers

5. After the file is successfully expanded, type exit, and then press ENTER to exit Recovery Console.

6. Restart the computer.

Error Message:
Windows could not start because the following file is missing or corrupt: \Windows\System32\Drivers\Isapnp.sys.
Translation:
This is another one of those messages that points directly to the culprit. ISAPNP.SYS is a device driver WinXP needs to function properly. The message is telling you this file is either missing or damaged.

Most WinXP files with a *.SYS extension are Windows device drivers that reside in the C:\windows\System32\dRIVERS folder. This folder is one of the most important in your entire hard drive. If any of these files go AWOL or are damaged, WinXP will report serious errors and you won’t be able to get your system started until you restore a functional device driver.

Solution:
Start the Recovery Console. If the ISAPNP.SYS file is still in your C:\Windows\System32\DRIVERS folder, the driver is corrupt. Rename the existing file and copy a new version from your WinXP installation CD. If the file is missing, then all you need to do is copy the file from your WinXP CD to the C:\Windows\System32\dRIVERS folder by typing the expand command: expand [CD drive letter]:\i386\isapnp.sy_ C:\win dows\system32\drivers\isapnp.sys.
