SP2 install prevents my PC from booting! (WXP-Home) Big nightmare time... I installed SP2 from a CD and it seemed to go Ok and then asked me to restar t the computer... Now it won't boot! It gets to the Xp home start up logo and screen, then the screen goes black and there it stays. I tried to repair install by booting from the windows XP cd. However, the PC can't 'see' the old install and just offers me the choice of a new partitio n or installing over the old one (ie I loose everything!) I tried safe mode (sceen of drivers then it stalls), along with all the othe r booting options - but no good! I then tried the Recovery Console option from the XP disk. This goes Ok unti l it asks me for the administrator password.. I don't know it! This is my p arents PC and I set it up for them from new, but can't remember giving it an administrator password. I have tried all my normal ones, as well as 'administrator' enter, blank etc ., but all to no avail. I went to Windows knowledge base, but all their possible solutions involve u sing the administrator password! They do say thought that this will happen o n some computers when you install SP2! I tried a patch at http://home.eunet.no/~pnordahl/ntpasswd/ to find the administrator password but this also didn't help. I can put the hard drive in another PC as a slave drive, but if I do that what do I change or edit to make the disc bootable again? According to the Microsoft help files, if I can dual boot the discIi can: "Method 2: Start an alternative Windows installation If your computer is configured to start from multiple Microsoft Windows installations, follow these steps to start your computer: 1.

Well I can put the HD in a different PC as a slave, but I'm not a DOS expert and don't understand what the commands in the above bit mean. What files should I do what with if I do get access to my disc files? Alternatively, what XP files do I copy from my working PC to the other disc to get it working? Any suggestions anyone????? Please!!
