I am new here. And I may replace a laptop's hard disk with Ubuntu. It's an HP Compaq notebook which has Windows 7 installed. So If I choose that install option, will it replace the screen that says F12 for boot options [actually it was esc]. I am just asking. I know that choosing that options erases your other partitions. I am assuming it gets replaced by grub2?
The Erase disk and install Ubuntu option will cause all partitions on the disk to be erased, including the protected system and recovery partitions. It will also delete all your programs, photos, music and any other files in all operating systems, including all other operating systems themselves.
When you install Ubuntu, the GRUB bootloader will replace the existing Windows bootloader, but it will not replace the HP Compaq notebook's splash screen that appears during boot before the Windows logo appears on the screen. The splash screen is a function of the motherboard that provides a visual cue for accessing the BIOS. Because the splash screen is determined by the computer's hardware, replacing the operating system will not have any effect on whether the splash screen appears when the computer is started.
If you are installing an Ubuntu guest OS on a virtual machine the Erase disk and install Ubuntu option will erase all the data that is stored in the directory that is dedicated to the new Ubuntu installation and then install the Ubuntu guest OS in that directory.
