I am currently running dual-boot Windows 8/Ubuntu 12.10. My current partitioning is shown here:
/dev/sda is 931.51 GB and has a GPT with :
- 500MB Windows RE Tools (ntfs )
- 300MB /boot/efi (fat32)
- 128MB Microsoft Reserved Space
- 811.67GB Windows 8 Installation (ntfs )
- 85.71GB Ubuntu Installation (/) (ext4 )
- 7.89GB Linux Swap
- 24.33GB SAMSUNG_RECOVERY_2 (ntfs )
- 1GB SAMSUNG_RECOVERY (fat32)
/dev/sdb is a 7.46 GB SSD and I have no idea what it is used for. It is marked unknown in GParted, and was default unmounted when I got the computer (with Windows 8 only). I think it may have been the hibernation file, but I've already disabled hibernate.
When I was setting this up, I assumed I would mostly use Windows and didn't know much about Linux. I now use Ubuntu around 95% of the time, restarting into Windows only for games that won't work in Wine. I realize that 8GB is alot of swap, especially as I have 8GB of RAM, but I do a lot of gaming and heavy duty numerical computation (C++ programs dealing with 100million entry arrays, etc.), so that's why.
After reading around on this site and others, I want to repartition into something like the following setup:
- 300 MB /boot/efi (fat32) (leave as is)
- 25 GB / (ext4 )
- 40 GB /usr (ext4 )
- 10 GB /var (ext4 )
- 8 GB SWAP
- 100 GB Windows Installation (ntfs)
- 25 GB for installing/experimenting with other distros
and the rest for an Ubuntu specific /home partition (ext4) and a /home/data (ext3) partition used by Ubuntu, any other distro I have installed and Windows with ext2fsd. I got the idea that this is better than just a shared /home from here: http://askubuntu.com/a/55233/170770
Sorry for the long leadup. My questions are these (not sure if they should have been separate questions, but figured this was clearer):
- Does this setup make sense? Is there anything else I should include?
- I have heard that even if you don't touch them, if you repartition at all, recovery images no longer work. Is this correct? If so, I should just free up that space, right? I did make a recovery USB when I first got the computer.
- Can I safely do that radical a partitioning change without reinstalling the OS and everything?
- Am I correct about what the SSD is likely being used for (the Windows partitioning system just says it's a healthy primary partition). If so, where should I use that extra speed? The obvious place would be /, but even with separate /usr and /var, is 8 GB big enough for / ? Would swap be a good idea there?
