@Wayne-Workman Hi Wayne,
It seems that the problem is resolved now. The problem appeared to be in the image upload with this 102 MB partition. I’ve booted a gparted iso from CD and removed this partition, then I booted a Windows 7 DVD to recover the drive as it didn’t want to boot with this 102 MB partition.
I totally agree with your remark about the vulnerabilities provided by the manufacturer’s image, but I’ve been completely striping that out.
Besides, I cannot use an OEM license key when I install Windows myself. For this reason I’m stuck with this image. I need to buy retailer CD key’s instead for about 60 machines.
Thank you very much for your help though, if others have simular problems with OEM images provided by manufacturer’s, I might be able to help them.
