I've tried to hit ''enter'' key severally when it prompts for admin password but it still says ''invalid password'' man what do u think?? And when I hit enter 3 times, it says ''invalid password enterd 3 times, press enter to restart'' what else pls!

Have you got another computer that you can use?
You might need to get a cable so that you can attach the laptop hdd to a pc and remove some files manually.

Mhookem, please wouldn't it be possible to removes those files via my vista partition. I mean, loggin into the vista partition and then accessin the xp (D) partition as a 2nd backup partition to remove the files cos am so scared of loosening my pc besides, I dont have suitable tools. Please..

So can you still use vista?
Have you ever heard of easybcd?It's free to download and you can repair your xp boot with this software while running vista

Mhookem, yes bro, I have that software ''easybcd'' and I can boot and use my vista. please can you describe to me how I can repair my xp boot from the vista using the ''easybcd''. Thanx a lot

As far as Im aware there's a button that automatically fixes any problems with any of your boot files.
Can you see an entry for your xp partition?

Ok thanks a lot. In the application interface, I can see my 2 partitions.. Xp and vista. But I just wanted you to give me a step by step method on how to fix my xp using the ''easybcd'' so I dont make a big mistake or damage my vista partion. Please.. Tanx.

OK dont worry about easyBCD right now, can you access the the boot.ini file for your xp OS?
If you can copy and paste the bootloader entry please.
When you set the boot mode to safeboot it should've added an entry at the end, something like this '/safeboot:minimal'.

You should see the boot.ini file on the partition without going into any folders.

Thanks mhookem. At a time I began to fiddle wit d system cos of that and caused a little more complications and cos I ran out of patience, so I reinstald d xp bt didnt format so d raw files I hav on d partition were not tampered wit. Bt d problem now is am sure my vista wont boot after dis setup.

No don't worry, vista uses the BCD and xp uses boot.ini.
All I want you to do is remove the safeboot part, this will stop it booting into safemode.
If this doesn't work you're going to have to access the windows folder of XP and remove the SPTD.SYS file that is causing the problem.
Or you can remove the SPTD.SYS file first, and then use msconfig to change from safeboot.
Copy and post your boot.ini file for me.
