How to boot Linux and Windows (7) via UEFI

Don’t.
It’s a fucking pain in the ass.
Buy a <=2TB hard disk for Windows installations (additional Windows partitions can be on larger HDDs using GPT, it’s only painful for the system partitions).
However, if you want to use a hard drive with >2TB for your Windows installation, you have to use GPT partitions (instead of the old MBR style which only supports <= 2TB disks – there you can only use the space >2TB with ugly hacks and can’t have a continuous partition from 2TB) – and Windows can only boot from GPT partitions in UEFI mode.
To make things more challenging, Windows doesn’t offer creating a GPT partition table and partitions in the graphical installer (at least for Win7), so one has to use cmd.exe.
But don’t worry, the Linux part also sucks :-)
I’ll describe how I got Windows to install using GPT partitions on a 3TB harddisk, how to make an existing Linux (Debian Wheezy) installation boot via EFI (using grub-efi) and how I got my Mainboard (ASUS Z87-A) to boot this and GRUB to chainload (UEFI) Windows.

Remote administration/tech-support with (reverse) VNC

Like most computer-savvy people I am frequently asked to give tech support to my family etc. Because telling them on the telephone what to do is a major pain in the ass, VNC is my weapon of choice, if SSH isn’t sufficiant (got to show how something is done, SSH impossible/hard because the other side uses Windows or is behind a NAT, …).

I’ll describe how to set up a normal and reverse VNC-connections using x11vnc and TightVNC.
