Re: Dual Booting
Depends on what is on the PC at present.
If there is ONLY Win7, such that it fills the drive and there is no space for Ubuntu, do NOT, repeat NOT, just follow the install directions and use the slider to shrink Win7. That runs the risk of corrupting the Win7 boot loader -- essentially negating all the work you just did. Instead, use ONLY the Win7 Disk Management utility to shrink Win7 to make some room. And after that, reboot into Win7 a couple of times so it can make filesystem adjustments. Do not create any new partitions with Win7, just leave the space alone. Then, when you boot to install Ubuntu, use the "something else" option to create the partitions.
If Ubuntu is still there on the drive, and all you want to do is install over it, then use Something Else to select the existing partitions.
Ubuntu 16.10 Mate, Mint 18 Mate; MS Win 8.1, MS Win10 Pro.
