TIPS: Issues while compiling WXWidgets
If you have msys installed & added to the path then WxWidgets failes to compile and you will get the error which starts as follows
if not exist gcc_mswd mkdir gcc_mswd
The easiest solution to resolve is in the command prompt remove all the path folders except windows & mingw paths and then try to recompile in the same command window.
Tips: Python : wxFormBuilder v3.1.67-beta (Febuary 18, 2010) Python Update
Latest version of wxFormBuilder does not support wxAdditions fully, thus I have updated few XML files to support FlatNotebook & wx.propgrid widgets.
- Download wx.propgrid and install it.
- Download the XML.Zip folder and extract it in plugins\wxAdditions\xml folder.
- Restart the wxformbuilder.
I did not tried to update these files for other widgets but it should be similar.

- Repartition your drive
- Base Partition – This is were your winXP is installed
- Image Partition – this is were your image of windows xp will be copied

- use the command to restore the img: ntfsclone –restore-image -O /dev/sda1 /media/img/winxp.img
