Have you recently installed any new software or a new drive?
In order to act on my suggestion, you'll need to access the recovery console from your windows CD. If the error you listed happens when you try to boot from the CD, then start ignoring the post here**---------------------------------------
You said you're having trouble booting from CD, do you know how to access the BIOS on your system? On many systems, you hit F2 while the computer is first booting-- Don't hit it more than once per second or you risk locking up your keyboard-- but not on all of them (mine is the DEL key). It should say at the bottom of the screen before windows begins loading.
Once you're in the BIOS... understand this is by nature general directions since I don't know what kind of system you have... You'll need to find the boot order. Change the disk drive to first in the order if it is not already, and then exit your BIOS (be sure you save changes). The computer will restart, and hopefully let you boot from the CD.
When presented with the option, boot into the recovery console. It should bring up a command prompt. The first thing I would attempt is to replace the file directly that is listed in the error message. I took a peek at my windows CD, and halaacpi.dll is listed as DL_, so we'll have to change the extension. For the following commands, I'm going to assume that you're using the default windows root directory, that your hard disk is drive C:\ and your CD is in drive D:\, if this is not correct, please put the correct drive in front of the command lines. Also, as always, remember that we are messing with system files. These directions come with no liability or warranty, expressed or implied. That sounds suitably legal, right?
First, we'll back up the file in question. My PC doesn't have it apparently, or the folder listed as containing it in the BleepingComputer database, so if this directory is invalid get back with us and we'll go from there.
copy c:\windows\ServicePackFiles\i386\halaacpi.dll c:\ (This puts it in a nice easy to remember spot in case we need to find it later)
copy d:\i386\halaacpi.dl_ c:\windows\servicepackfiles\i386 (This pulls the file from the windows CD onto your computer in the same directory as the old file)
rename c:\windows\ServicePackFiles\i386\halaacpi.dl_ halaacpi.dll (This changes it to a functioning system file.)
You should be asked if you wish to overwrite the file, say yes. Do the following ONLY if that previous line doesn't go through...
rename c:\windows\servicepackfiles\i386\halaacpi.dll halaacpi.txt (changes the apparently faulty file into a harmless notepad document)
... And repeat the previous rename line.
Next, I would run these commands for good measure; sfc /scannow, followed by a chkdsk /r to make sure your hard drive is in order. Its a good idea to run a chkdsk every now and then anyway. Please note down any error messages recieved.
---------------------------------------------------------**Stop ignoring here if message is from CD boot
If that error message was listed when you try to boot from CD, then what exactly happens when you try to boot into windows? Can you boot into safe mode?
I hope this helps, but please try to be more detailed, it helps a lot to know specifics.
EDIT: A note, if the error occurs when booting to CD and you are able to access it, this can be done exactly the same through safe mode: command prompt
