standalone. Is this win8 professional or home? Are you trying to upgrade win7 here? So wind7 no longer exist because of format?
I was installing Windows 8 on to my pc that I have just built, When it was 0% Getting files ready, It said Error: A file is missing or corrupt. Error code 0x80070570. On that HD I had Windows 7 Professional and I had an error that LogonUI.exe Entry Point Not Found. So yea. I really need help. The disk is formatted so I cannot access Windows 7. I got the iso and burnt it to a disk. Booted the PC from the DVD. I have a Windows 7 Professional Disk but no key and a Windows 8 disk with a key.
