I am getting this message on my daughter's PC "Windows could not start because the following file is missing or corrupt windowssystemconfigsystem You can attempt to repair this file by starting original windows setup using CD Rom select “r” " I have checked and I know that her hard drive has a boot sector virus. It will not let me run the Windows XP disk nor will it let me "see" the hard drive when I boot from A. I have a clone drive but my daughter's files are on the one that are infected. Perhaps I could take the mbr file off the clone and somehow copy over the MBR in the infected drive. Any ideas?

Re: boot sector virus
Hi, regardless of the amount of users on the pc, the virus is resident in the pc, not a persons profile. Bad news is the only way of 100% resolving this is by a fresh install of the operating system. Place the operating disk in the cd drive, shut down and reboot, click fresh install from the options that are presented to you.

You can obtain Windows XP Setup boot disks from Microsoft, but only by
download.They provide the Setup boot disks so that you can run the Setup

your computer from a CD-ROM or from a network-based installation, we
strongly recommend that you use those installation methods instead.

Then you can type the following at the dos prompt:
fixmbr - Fixes corrupt master boot record
fixboot - Fixes corrupt boot sector
bootcfg /rebuild - Fixes corrupt or missing boot.ini
