The maker may not support use of the SFC or other commands. They give out a crippled OS that the only fix is the reinstall. Be sure to ask if SFC is supported or not.
New (to me anyway) Inspiron 1505 notebook, OE installed Media Center XP, works ok, full DVD of MCE xp ( dell actually ) came with it, just for my own amusement after adding more memory, cleaning out lots of fluff the previous owners accounts had left behind (Actually just deleted the accts, browsed the saved stuff then recycle bin-ned it. I tried to run SFC /scannow, insisted on the disk, then said it was not present. Browsed to where the oe setup i386 folder was, checked / changed the registry entries to point to it (C:\Dell\i386) still insisted I put in CD, so I copied the DVD's i386 folder to C:, changed the registry to point to it and sfc now says, "Wrong disk" ?? How can that be? How can I figure out what kind of disk it wants? (I tried a known good XP-Pro SP2 cd, same thing- is there a key in the registry that ties them together? Correct and legal COA's everywhere, I plan on scratching my head for a while- or should I just reload the thing? Or would a repair install correct stuff? TIA..
