Hi everyone.
As a favour to a work colleague I offered to try and speed up his exceedingly slow pc. After doing this I noticed he had 2 Windows XP Home Editions during start up. After doing a wee bit of reading I discovered this was down to a partition error. However, on trying to solve this I have caused this:

Windows could not start because the following file is missing or corrupt.
Windows root\system32\hal.dll.
Please re-install a copy of the above file.

So after more reading I discovered the solution to this, is to reinstall the missing or corrupt files. Sound easy until the pc won't reboot with the CD.
I've checked the BIOS to ensure it's booting from the CD, but still no joy.

Can anyone help???? PLEASE

you're probably getting the error because the boot.ini file is pointing in the wrong direction. You've almost certainly deleted the working windows version and left the non-functional one on the drive, and as a result the boot loader can't find anything to launch

the fact you appear to have had two version of windows on the machine implies this is a long standing problem and some one else has already had a go at it before and screwed it up. Quite possibly one of the reasons its running slow

In a case I this I always feel its best to cut your losses. You're not going to easily repair the software. Instead just reformat it and reinstall windows and the software from scratch, or if you have a recovery disk from the supplier, use that

Don't forget to find a way of backing up all his data first - either by salving the hard drive to another PC, or using a "live" CD to boot the machine and copy the files to CD/DVD


FYI the dual boot problem wasn't due to a parition error - its because someone tried to "repair" the machibe by overinstalling a new copy of window - and got it wrong. "Repair" installations are really best avoided unless you need to get a machine running to extract data - and even then there are better solutions

"the pc won't reboot with the CD"

sorry - I overlooked that earlier. Does not affect what said, it just means theres another problem as well

several possibilities
faulty CD
faulty CD drive
bios that wont allow CD to boot because it can't detect it (even though you can select CD as first boot...) - surprisingly common on some machines from 9-10 years ago.
you've got a USB drive plugged in

you'll find some machines will boot from a recovery CD but not a windwos CD (or vice versa) so try other botable disks
