I have 2 operation system on a same computer(A\CDrom\C: is window 98)(D:\ is window NT). I download the sp6patch_i386 from the net and instal it to my NT, after doing so i cannot boot back to NT it have a error message saying {DLL initilization fail} initilization of the dynamic link library D:\WinNT\system32\user32.dll fail, so after that i made a biggest mistake, i went to my window98 try to copy the USER32.DLL and paste to my D drive which is NT, after boot again different error message on NT {Illegal system DLL relocation} the system DLL USER32.DLL was relocate in memory the application will not run properly the relocation occurd because the DLL dynamiclly Allocated memory occupied on Window NT system DLL. that all the message say. i really need help if anybody know about this please help. Oh by the way i don't have a recovery disk, i have this computer pretty long so no idea wher it is.

- maybe you can boot into the recovery console (hit F8 during boot)
- you can recreate the recovery disks from your installation cdrom
- you can download a tool to create these disks from www.microsoft.com
- another way: reinstall NT
