Tutorial on how to use the Ubuntu Manual Drive Partitioner (Something Else option) provided in the Ubuntu system Installer.

FAT32 tends to be a small bootup partition
NTFS is used for Windows and Windows backups
Ext4 and Btrfs are generally used for Linux systems

You’ll also need a Linux Swap partition, which should be at least 1Gb, but its worth allocating more if you have enough harddrive space available.


  1. I shrinked my drive by 50,000 MB and it displayed as unusable memory 50,000 MB while installing ubuntnu .Then I tried to create a new partition and removed 50,000 MB from the drive(while installing ubuntu) expecting to get it as free memory but it again added to unusable memory. Now I lost my 100,000 MB. But I didnt get my ubuntu installed. Please help me to install ubuntu

  2. Well if you have a desktop you could have both an ssd and spinning hard drive. Althuogh custom built desktops are easy to get enough space and place for disk. This is quite helpful as if you want to store a lot of say music or videos locally you can get all the speed of the ssd for system and really quick program launches and yet a lot of space for documents.

  3. I got a new laptop and installed Kubuntu with the Use Entire Disk option. When I rebooted the bios started and said it doesn't find any OS's. I tried creating the partitions manually with a separate partition for GRUB but didn't work. I had to install Windows so it creates the bootloader partition then install Kubuntu and delete Windows. It's quite annoying. Can someone tell me what could have been the cause.
