If this is being caused by a347bus.sys … try booting to a Linux LiveCD/LiveUSB, then navigating to the Windows drive, then \Windows\System32\Drivers\
and MOVE
a347bus.sys
and
a347scsi.sys
To somewhere else on the drive … don’t delete them … move them.
Then see if XP will boot … if not, try a REPAIR install:-

FYI … those 2 files are part of the Alcohol virtual CD suite.
It may also be a good idea to run chkdsk from the XP cd’s recovery console … do you know how ?
Hi Mark,
Running chkdsk from the recovery console gives
chkdsk found one or more errors on the volume
109506832 kilobytes total disk space
60219696 kilobytes are available
MOVE is not one of the commands available in recovery
There is a DISABLE command that I could try (it also has the ENABLE command to restore)
take care

First … Did chkdsk say it had fixed the errors ?
If not … from the XP recovery console try running
chkdsk c: /f
(sod it … run that anyway)
then see if XP will boot … if not …
Read my last response again 
… use a LINUX LiveCD to move those 2 files 
Then see if XP will boot.
If not … try an XP repair install.
Or…
You could burn G-Parted to a CD. Wipe your harddrive, and install Windows?
Hi Mark,
I followed the How to perform a Windows XP repair install.
All went well until it asked
The file VIAAGP1.SYS on VIAAGP Filter Driver Disk is needed.
Type the path where the file is located, then click O.K.
I am off to bed

That’s part of the VIA/S3G UniChrome Pro IGP driver … easiest way past that message is …
VIAAGP1.SYS should already be installed on the system … so when it gets to where it asks for it, select “Browse” and pointed it to the C:\WINDOWS\System32\Drivers folder … it should then display the VIAAGP1.SYS file, select it and continue.
If you get any similar messages for other files … try browsing to:
C:\WINDOWS
then
C:\WINDOWS\System32
then
C:\WINDOWS\System32\Drivers
they’ll most often be in one of those 3 directories.
Ideally, you’d have the proper drivers unpacked and on a disk somewhere … but 99.9% of the time, pointing it at the already installed file that it’s looking for is fine.
[EDIT]
Erm … how the heck have I ended up doing unpaid Windows support … and on a Linux forum at that ???
Hi Mark,
I have found the the file needed on the motherboard disc and installed.
I carried through the install and when I rebooted it said ‘Error loading Operating System’
I then opted for a clean install from the XP CD with the same result >:(
I have now installed PeppermintOS 2 on this machine and am using it to write this.
Goodbye Windross ;D

Bit odd that … did you use Windows to create/format its own partition ?
see here:
Yes Mark I carried through all the instructions as they were copied from the EHow site.
I am happy that Linux is installed on my main machine, I will try and put XP and Autocad on the other machine.

Hi Mark,
I have installed XP on this machine and have set up an internet connection.

Glad to hear you’re all sorted now
