Either way, select the option for the failed install or Windows 7 depending on what you see.
The install might grind a bit as it recreates the install files and finds its place, but it should resume within a few minutes. Even if nothing happens on screen, the hard drive should be thrashing.
Should you have a hardware RAID setup and see a message stating that a required driver is missing then Browse to the location with the RAID driver, e.g. a USB stick, select the driver to be installed, and hit Next. Else, skip this step.
In an ideal world, the installation should now proceed without an issue, but this isn’t an ideal world and it may not.
If the install fails again, have a look at your hardware configuration. Do you have anything exotic or rare connected to it? If you have a pretty standard system, then consider removing things like webcams and printers, as these can cause an issue.
Try the install again after removing all the peripherals you can. Follow the same steps as before to re-initialize the setup program and see if it progresses. If it fails again, then look inside your PC case and remove everything except the hard drive you’re trying to install onto, the DVD drive with the install disk and the graphics card. Strip the system down to the bare bones and repeat the steps above.
The install really should work now, but if it doesn’t, reboot, and boot from disk again. This time select Repair from the Install screen and then select Startup Repair. This will try and reassemble the install files in order to allow you to boot back into the loader.
If this doesn’t work, the last resort is to format the disk and begin again. Reboot the machine, choose to boot from DVD, let the setup load and select Install again. Choose the Custom install option and then follow the instructions to format the disk before starting a new install.
This time if it doesn’t work you can be pretty sure it’s a hardware issue, and that’s a whole other story!
