I upgraded my Dell Inspiron530s to Win7 with Win7 disk I bought at the PX a few years ago. I recently moved back to the US and I cannot find my Win7 disk. My Dell won't boot and it is asking me for the orginal disk to boot from. IS there a way to get a bootable disk so I can repair my computer? I have the original Dell disks but I think it used Windows Vista version. Can someone advise me? Thanks.
