(see edit 3, the following paragraph is now quite invalid)
I'm having partitioning issues with Xubuntu 12.10 64 bit. I reduced my Windows partition by 500GB. I now have a 1450GB Windows partition, 500GB unallocated, 50GB recovery partition and 1GB "OEM" partition.
I bet I shouldn't remove the recovery and OEM partitions, else my warranty could be voided (edit: not that important actually), or worse, computer could be unbootable.
I can't create new partitions in the unallocated space from the live CD's installer and gparted; the only automated partitioning options are "Replace Windows 7 with Xubuntu" and "Something else".
 This is a computer with UEFI.

[edit 3] I might just end up removing all partitions and install Xubuntu -- I've used Linux for a long time and I don't think it is worth it because I'm not running any Windows-only software.
Here comes my two other questions:
1) Maybe -- since I'm not running any Windows-only software, should I attempt creating a new partition table and install Xubuntu instead? Will the computer be bootable if I do that?
2) I do play games on this computer (they do have native Linux versions) and I have a NVIDIA graphics card; the Arch Linux wiki says the proprietary NVIDIA driver cannot be used if using UEFI, is this true for Ubuntu and its derivatives?
