Win XP Service pack 3 problem...

[digit i am thinking]

When i First try to install it gives error

Service pack 3 setup cannot update a checked (debug) system with a free (retail) version of service pack 3, or vice versa.

then i followed this :

Open regedit and goto:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion
​

2. In right-side pane look for a String value "CurrentType". Change its value to Checked and if its already set to Checked, then set it to Free and click on OK.
3. Exit registry editor and try to install SP3 again. Now it should install without any problem.

But after that my pc keep rebooting and can not start win XP.

I have to restore it to SP2.


ANY one got Soln for this?
