I just brought home my brand new XPS 15 L521X. I booted to Ubuntu 12.10 using a memory stick to check that the wifi and everything is working (it is). I am wanting to wipe the drive and install Ubuntu, and I don't really care about secure boot.
The only description of the hard drive on the site was "Up to 750GB SATA hard drive (7200RPM)" so I was a little surprised with what is actually in there:
And now the good surprise... an SSD! The 8 gig partition is EFI.
My instinct is to get rid of all the crazy little partitions on /dev/sda and probably use it for my home folder. The SSD on /dev/sdb I was thinking I would use for / so the OS would boot quickly.
Is there enough space on the ~29 Gig /dev/sdb drive for the OS?
Is deleting the EFI partition a mistake? Does it mess up firmware upgrades?
Is there any reason to keep any of those OEM partitions if I am never going to use Windows?
