Currently, I stopped support for other activities.

I work in industrial software (mostly in aerospace) with Unix since 25 years.

Currently, I help mostly on
   installation process from CD/USB key (excluding Wubi and Mac OS multi-boot) i.e. ubiquity
   grub2 (excluding RAID configuration, LVM, Mac and issues about graphic card)
   partitions
I use daily VirtualBox, and can also help.

For Wubi, set project link to "Wubi" and an expert will answer.
