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
