Corrupt installation media.not be able to download it as my systen is now not working
i am able to install windows xp but not able to install Windows 7 don't know why this happening? can anyone explain why this happening?
You've got a point. But he has already said this.Corrupt installation media.
i have tried 2-3 different dvd, but same thing happening, and I have tried to install the OS in Vmare its getting installed there.... only not able replace my current OS.
Seems unlikely, but how about testing the memory. Or even you may test the HDD for errors?yes i tried that also.
Is installing via USB drive also not working?i have tested the hdd and the windows dvd is also working disk as my friend have installed his windows 7 from that dvd
