ok so i bought this Dell Latitude D266XT it is a Pentium 2 266mhx MMC-1 processor

I bought a P2400MHX MMC-1 processor to put in it, the processor works great but now i get an error message when windows wants to boot up that a file was corrupted and i need to repair windows

fine, so when i try to use the repair disc it gets the to windows setup screen and doesnt do anything

I tried using my roomates hard drive, we bought the same laptop from the same deal, and it said the same thing

I tried using my hard drive in his laptop and it worked fine

Im out of ideas, is this processor just no good or is there something im forgetting?

thanks

You will have to reinstall the windows.
Changing CPU means that windows will no longer work, because it was set up to work with your old CPU.
If you meand by "repair disc" a setup CD, then just place your hd in your friend's laptop and format it via setup program. Put the hd back and you will be able to install windows now.

Let me explain a little better, I tried my HD in my friends laptop WITHOUT uninstalling windows and windows worked, but when i put it in my laptop it doesnt work

I cant reinstall windows, because when i do it always gets hung up in the install menu and i have to restart

That's because you have different CPU now.

but how can install it on my laptop if it keeps freezing up? if i install it on my roomates laptop it will think it was the same 266mhz processor it was before so i will probably run into the same problem as before, im actually using a win98 disc to run scandisk, its finding problems and fixing them, ill let you know how it goes

thanks guys

Did your friend change CPU also? And if he did, is it same model?

it didnt work, but i can get to the c prompt so im going to format my C drive and see what i can do

i changed it, i changed a MMC-1 Pentium 2 266mhx with a MMC-1 Pentium 2 400mhz, they have the same bus speed and are the same processor, one is just faster, obviously, the processor works great, i think the hard drive might be a peice of crap though, its kinda loud, i bought another one its on its way

ok so it wont let me format

i tried to install win98 and it froze just like before

im lost again

correction, the win98 isntall is working, just REALLY REALLY SLOW

ill post again in a few hours, lol
