Hi, Whenever you make system changes or repair a machine it's wise to create an "audit trail "in the form of a record of exactly what has been done, so that in the event of trouble it can be "undone"
In the workshop we do this as a matter of course (taking screen dumps where appropriate) and using a cheap digital camera for recording and cross referencing, wiring or screen photos that may be helpful to us, or more often the customer.
If you haven;t done this don't worry…….for a start go to :
1 My Computer and see if you have created an extra partition, do you appear to have an extra drive that wasn't there before?
2 Whilst in My Computer have a look in C:\ and see if you have an extra folder called Windows 0 or any other name that starts with Windows and then has a number, you should only have one copy of a folder and that should be C:\Windows…anything else with a similar name could indicate Windows has been installed twice on the same partition( not a good idea!)
Check the folder size…is it consistent with just one copy of Windows…….Have you "lost a large amount of disc capacity?…(This would be consistent with two copies of Windows)
3 Start>Run and type MSCONFIG and hit the enter key, Click on the boot.ini tab, it should look like this:
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect
4 Let us know if yours is different (my example is from XP pro)
5 As your machine is running well with no problems…..proceed with great caution…only alter things if it's necessary!
6 Further info from the link below.. will be helpful if you have two copies on the same partition…..but I would always start completely from scratch as a rule,(Wipe everything and start again…..if you do this check your back up/archive is 100% accurate up to date, reproducible and kept safe on removable media, however the article is authoritative and does work if you follow it carefully!
