Why do you need to boot without UEFI at all? The Windows Installation DVD's used for repairs should boot into UEFI mode.

Not the Dell Windows 7 Professional. Hence the problem. I am still trying to figure out, with UEFI disabled, why UEFI comes in to play at all.

If you mean you cannot switch between UEFI and Legacy on a system currently running Windows you are correct. Like switching between SATA and AHCI on the fly. Not good.

While in theory UEFI CD can make partition table and vice versa - no system installer in the world does that.

I have not gone real deep in to UEFI. I have a Dell Optiplex 3010 that booted to the &quot;You need to repair Windows&quot; screen. The only CDs that would boot are ones that have a UEFI option. I went in to the BIOS on this computer and UEFI is turned off yet it would not boot a standard Windows 32-bit CD. I double checked every UEFI option in the BIOS and it is turned off. Any ideas?

Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers. For large systems, the operating system makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system. Operating systems provide a software platform on top of which other programs, called application programs, can run.

Operating Systems

Installation is the act of making a computer program program ready for execution. Because the process varies programs often come with a specialized program responsible for doing whatever is needed for their installation. Installation may be part of a larger software deployment process. Cross platform installer builders that produce installers for Windows, Mac OS X and Linux include InstallAnywhere, InstallBuilder and Install4J. Installers for Microsoft Windows include Windows Installer, InstallShield, and Wise Installation Studio; free installer-authoring tools include NSIS, IzPack, Clickteam, InnoSetup, InstallSimple and WiX. Mac OS X includes Installer, and also includes a separate software updating application.
