Thanks to the people behind http://code.kliu.org/misc/winisoutils/ I could help someone with a laptop that had a completely broken harddisk with Windows 7 home premium installed. Off course never made a backup / recovery DVD so my hands were empty.

Using the eicfg removal utility is a pice of cake and the result nice:

A universal installer DVD is always handy.

But the subject covers this post very well: the Windows 7 DVD I used with eicfg removal utility is unusable for a Packard Bell laptop as is explained on Microsoft answers (in dutch) http://answers.microsoft.com/nl-nl/windows/forum/windows_7-windows_install/product-key-home-premium-werkt-niet/756bbf93-1977-42b0-a3aa-c6c594d19974
