i have recently encountered a problem where a critical file was erased from my harddrive....

my computer is stuck in a cycle of rebooting ---> black screen offering to start up in safe mode, last known good configuration, or normally ---> select any option ---> reboot

i have tried numerous fixes and discovered i am missing a file "system32\drivers\pci.sys"

the literature online states to use the windows CD and run a repair on my computer however i do not have access to these CD's, i have downloaded the missing file on another computer however cannot find a way to install it into my other (broken) harddrive.....


any suggestions? THANKS IN ADVANCED

dell dimension 8400

pent. 4 proc
512 ram
160 gb space (not used up)

Try running the chkdsk program. It runs from the command line, but will require a reboot in order to complet the routine.

To run chkdsk you need to do the following:

Start >> Run >> cmd.exe >> Press [Enter]

OR

Start >> All Programs >> Accessories >> Command Prompt

When the command prompt window opens, type the following:

chkdsk /f/r

And then press [Enter]

It will give some coding syntax returned and ask if you want to run chkdsk at next boot. Type 'yes' or 'y' whichever answer will indicate that "yes you want to run chkdsk at next boot".

You can get more information about the chkdsk command by typing the following:

chkdsk /?

Press [Enter]

If you cannot boot Windows and get to your desktop environment to run go through the Start -> All Programs menu, boot your computer to Safe Mode with Command Prompt. You may need to log in as the local administrator account on your machine to access the C:\ drive from the command prompt. If you haven't changed any of the default settings, the administrator password should be blank by default.

The check disk command routine will run a series of five tests, locate any abandoned or rogue files or sectors and attempt to repair them. You do not need the bootdisk to run the command and it usually fixes things up for you without having to go through an entire restore. It will troll the i386 folder to try and repair any damaged or lost files in your Windows installation.

See if that helps out.

Best of luck and happy hacking!

You could boot your computer using the UBCD and copy the file across to your hard drive.

hey BUDAPEST, since that UBCD has a ton of uses, could you point me in a specific path out of all those tools to the one that will let me copy a file from my floppy drive to my harddrive path "C:\windows\system32\drivers".


also, i didnt make it clear, i have not seen a log-in screen since the computer initially crapped out, just the command prompt every once in awhile.

BUDAPEST: do you think without the pci.sys i can completely format my C drive using the UCBD, that may be an option.

THANKS SO MUCH

You could use Necromancer's DOS Navigator (under File Tools) to copy the file to your hard drive.

You can format your drive with the UBCD, but you will need a Windows CD to reinstall the operating system.

sorry to be a bother, i burned the file UBCD to a cd so my computer (that is set to boot from CD before harddrive or anything else) boots from it.... it didnt.

is there anything special i need to do to start computer from this CD or access the programs within it (remember i have limited capabilities when the computer is turned on)

Well...did you make the CD bootable...before dumping files onto it?

A system can only boot a drive or device which is bootable...any other type will yield an error message or inactivity.
