While installing it take me to the blue screen where you get the option of installing XP or accessing the Recover Console. When I press Enter to install XP it takes me to the next screen where you should be shown the drives and any existing partition. Instaed it says No Disk In Drive. When I press enter it takes me to the next blue screen (you get this error screen usually ending with Memory Dump). It says that the system has been shut down and says that the problem might be because of sysupdd.exe.
I am also not able to format C: as am not able dismount the drive. Have tried everything (went into recovery console to format etc) but to no avail.
Please help as I urgently need to do this installation and start working.
