I bought a Dell XPS13 with Ubuntu 12.04 pre-installed. I want to reformat and repartition the machine, but as I'm far from being a Linux guru. I'm afraid that I'll erase something important that could have been preinstalled by Dell.
On the disk, there are 3 partitions:
/dev/sda1
- Ext4 Linux bootable 248GB - which is the system+user partition, I guess./dev/sda2
- Extended (?) of 8GB - What is this partition about?/dev/sda5
- Linux Swap of 8GB - which is for RAM and needs to be reconduct (why only 1xRAM and not 2?)
Do I have to care about /dev/sda2
?
Can I reformat to create a partition for /home
without losing anything important (except user data of course)?
