I am trying to make sure that I am able to boot from my Windows 7 CD in the event of needing to do a Windows repair. When I attempt to boot from the CD my mouse stops working at the moment that the initial "Install Windows" options open - e.g. selecting language, country etc. I have observed the red light in my corded optical mouse, and the light is on from the moment I turn my computer on, through the initial startup process, pressing any key to boot from CD, through "loading Windows files", but the moment the Windows options box opens, the red light in my mouse goes out. This means that I am unable to select any of the options or progress further. The only thing I can do is turn the computer off by holding down the power button. I have gone into the UEFI/Bios and checked the USB options. I have tried enabling all of them, including enabling legacy USB and the USB compatability patch, but this does not make any difference.
Can anyone tell me what I can do about this? I need to do some fairly significant registry changes in order to fix a problem I am currently experiencing, and I don't want to do this until I know I can boot from my Windows CD in the event of needing to do a repair.
