I have a Dell GX520 which refuses to activate. I have tried all variants of Windows7 formatting numerous times. Tried manually and all available loaders all to no avail. From searching the forums I conclude I am unable to change my bios. Two other laptops have activated successfully with loaders. I notice there is no separate 100mb partition for booting. Everything I have done is correct except this machine refuses to activate, perhaps if I delete all partitions (I only have a c and d drive) and restart from scratch as something is stopping the loader from working even after the drive is formatted. Any advice much appreciated.
