oh, that old msconfig issue.....someone from here tell you to do that?
We have actually had this occur with increasing frequency and are recommending people NOT use msconfig to set the PC to boot into safe mode because of this.
Do you have a Windows XP cd?

no....not really.
If you do not have a windows xp disk, download RC.iso from the following link:
http://www.thecomput...edic.com/rc.iso
You need to burn this image to a CD and boot your computer with it--this is different than burning a file to a CD. If you do not know how to burn an ISO image, then download the following program to another Windows XP machine, install it.
http://isorecorder.a...isorecorder.htm
make certain you download the proper installation for your version of windows
After installation, right click the RC.iso file you downloaded above and choose COPY IMAGE TO CD.
Then reboot your broken PC with that CD in the CD-ROM drive AND THE BIOS SET TO BOOT TO cd-rom FIRST.
i'LL WRITE UP SOME more instructions in a moment
This will give you a recovery console to use to run

you will basically do the same thing that you would do with the recovery disk above.
You will start the PC using the above disk, and you will be given a choice to repair windows using the recovery console after windows set up begins
Press R
You will be asked to pick a windows install...press 1 (on any single OS system)
You will be asked for the administrator password....in Windows HOME, press enter (no password) in Windows Pro, you need the password you entered when you set it up
you will then be sitting at the c:\Windows> prompt
type
bootcfg /rebuild
this will run for about 2-5 minutes depending on your CD. Windows will inform you it found a windows install, press Y for yes
You will be prompted to enter the load identifier. Call it New Windows, press enter
You will be prompted to enter OS load options. Type
/fastdetect
to automatically detect the available options.
type EXIT, and windows will reboot.
Now you will be presented with a windows menu, choose NEW WINDOWS by using cursor keys
Windows will load as normal
Right Click MY COMPUTER, choose PROPERTIES, choose ADVANCED, choose STARTUP AND RECOVERY, choose SETTINGS button, choose EDIT and you will get up something like
[boot loader]
timeout=5
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 safemode" /safeboot:minimal /sos /bootlog
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="NEW WINDOWS" /fastdetect /NoExecute=OptIn
It will not be EXACTLY like that, but close
You need to DELETE
/safeboot:minimal
Safe the file and close it
Reboot
Your normal window choice should now work
(not NEW WINDOWS)
If it does, go back to the above and delete the line that includes NEW WINDOW
If you feel uncomfortable doing that, copy the file by repeating the steps above and then posting the contets to another post and someone will tell you what to delete
In fact, that might be a good idea, but the above will get you going

that is most likely a windows recovery disk and it COULD completely wipe out your drive and all your data--preced with GREAT caution

it was the Windows XP disk. I followed your directions to the letter and everything is back. Thanks again. needless to say I immediately backed up everything!
