Did you enter Safe Mode using msconfig??
Thisi should work for you,thanks to our quietman7.
Using MSConfig to access (force) safe mode with the /Safe boot option when there is malware on your system could have disastrous results
and render your computer unbootable
. The Safeboot option modifies
file by adding the /safeboot:minimal
argument to your operating systems startup line. Some types of malware can delete or alter the safeboot key in the registry
resulting in the inability to reboot fully into safe mode or back to normal mode. When this occurs, you may be locked in a continuous reboot loop
afterwards where you cannot get back to MSConfig and undo your selection until the /safeboot argument is removed from the boot.ini. See Booting into Safe Mode safely
Problems that can occur by forcing Safe Mode
...If a situation like this has happened to you it is possible to fix this problem by renaming your boot.ini file. The first step would be to use a boot disk to start your computer. If your computer does not have a floppy disk, then you can typically boot off the Windows CD that came with your computer in order to access the Windows Recovery Console...Once booted to a command prompt, you would simply rename your C:\Boot.ini file to another name like C:\Boot.ini.bak. The command to rename the file at the command prompt is:
ren C:\Boot.ini Boot.ini.bak
Once the file is renamed, you can then remove the boot disk and reboot your computer to get back to normal mode. When booting up after the rename, do not be surprised if you see an error stating that you do not have a valid Boot.ini file. When you get back to normal Windows mode, you can then rename C:\Boot.ini.bak to C:\Boot.ini file and run Msconfig again to remove the /safeboot flag...
If you don't have your XP CD you can download a Recovery Console ISO file
and burn it as an image to a disk to get a bootable CD which will startup the Recovery Console for troubleshooting and fixing purposes. This is especially useful for those with OEM systems with factory restore partitions or disks but no original installation CD. If you are not sure how to burn an image, please read How to write a CD/DVD image or ISO
