I've got a Dell Inspiron 530 with Ubuntu in it. I just want to restore Windows, so I format the HDD, set partitions as NTFS. I then try to install Windows 7 Professional 32 bit on a Primary partition, yet without success. The computer still loads the Windows DVD, initiates the installation until it restarts. These lines appear from the restarting: "Boot from CD: Press any key to boot from CD or DVD....." And it just stands still since then! I also try with a Windows Vista, but get the same result. Please help diagnose and treat this symptom.
