Updating ubuntu from dual boot windows 7 dating queen sat 1
Of course I'm not talking about the operating system.It's just the same partition table information it used, also known as MBR (master boot record).Even without a dual boot computer it is recommended to keep your data on a separate partition, unless you do backups on external media.If you like Windows' user folder structure, don't worry.Modern OSes (Windows newer than 7 and 64 bits; Ubuntu newer than 12.04.2 and 64 bits) can be booted and installed in both EFI and BIOS modes.You just have to know how the primary OS was installed and boot from the installation media of the second one in the right mode. First of all you must decide where you install it and make some room for it. One is that whenever you'll want to do a clean install of the OS, you'll have to backup all your personal files and folders on a different drive, otherwise you'll lose everything. You'll need to access your files from both the operating systems.Linux distributions are becoming more and more popular.
Other distros, like Open Su SE, make also a separate /home partition.
But if you have a PC with lower RAM (less than 4 - 6 GB) it is recommended to make a swap partition (the equivalent of Windows' pagefile.sys), so when your RAM gets full, the system will start moving temporary data to this partition. In Ubuntu and any other Linux, we'll use the equivalent of Windows Disk Management, called GParted.
If it isn't installed you can install it with sudo apt-get install gparted (for Ubuntu-like distros).
Ignore the disk and partition values from screenshots (they are made on a virtual machine).
Now, if you already have a secondary partition for your data, you only need space for Ubuntu.
