Can anyone suggest how i may overcome a Windows loading problem on my pc? The os is XP Pro and after the bios info screen i get a message advising that Windows cannot start as ???.dll is missing or corrupt (i don't recall which .dll it is as i'm at a different pc at the mo). Can i use recovery console to copy the corrupt file or is there someother method of achieving this? The missing dll needs to be copied to the system32 folder however as i can't load Windows you can see where my problem lies. Any suggestions to easily resolve this issue would be great.

Can you get in through "safe mode"? If so this would allow you to remedy the missing file.
Windows won't load.

Yeah if you start up with your XP disk in the machine it will take you through as though you are instaling XP but just chose to Repair

Use the 'Copy system files' method from a Win XP SP2 CD, MUCH better than the recovery/repair method....

I've used this method several times and is also very handy if you do a major hardware upgrade.

All your progs will still run and profiles/files etc will still be intact, although you will need to re-install any XP updates that are not on the CD.

You should be able to use the recovery console while booting wioth the windows setup cd to copy it overm i had to do a similar thing recently.

You can always try installing windows over the current version as this sometimes fixes everything (more so on win9x though to be honest) and if it comes to it just reinstall windows by deleting the current windows folder, although this is a final step, but if you don't have a hardware problem will always fix it.

Update, Windows setup fails at ''The file acpi.sys is corrupted'' so i can't progress at all from this point. Any thoughts...hope i'm not going to be Donald Ducked.

The original error when booting from the boot drive is;Windows could not start because the following file is missing or corrupt: <Windows root>system32/hal.dll.

Is this a retail or an iso download (an msdn one) because there were a few problems with the iso that stoped (i think) at a point with this file.

So you pop the disk in, select boot from cd and then it starts to load the setup but then fails before you get any options?

If its a retail disc you should be able to get it swaped over as you may have a dodgy disc.

That is the long and short of it.
I'm fairly certain the disc isn't corrupt but i've got another i can try later.
