dual boot - Should I choose to Install alongside windows 8 or something else



I'm thinking about installing Ubuntu ( dual boot ) as I might like it but I'm not sure whether I should choose to install alongside Windows 8 or something else.



I do have 100 GB unallocated already for Ubuntu on my D:/ drive so I'm good to go.




I've seen people configure their partitions specially ( they created swap and then used the remaining unallocated to install Ubuntu ). Do I need to do this? Or will the installer handle it for me.



As far as I go, never trust automatic partitioning options in Ubuntu installers, as you may end up with nasty surprises. When installing Ubuntu, personally I always prepare the partitions manually. Since you want to keep a dual-boot set-up, most flexible would be to create a new extended partition and inside it create the several logical partitions.



In the extended partition I usually I reserve:




  • 5GB for swap (or whatever appropriate given your RAM)

  • 25GB for / which will contain all your system files (but some will say that this is overly generous, as 15-20GB could suffice given your installation habits)


  • the rest for /home which will contain all your user data



I tend to use ext3 file system for the above partitions for reliability reasons (but you could of course use ext4 or reiserfs if you so prefer). Sometimes I include a /boot partition no bigger than 500MB using ext2, but I cannot remember if this is more hassle than necessary; from memory, this is where kernels and grub config files end up.



Additionally, see My approach for replacing current Ubuntu with newer for a discussion on how manual partitioning can be approached.
