I tried everything last night. I used diskpart, made no partition and tried to install, it still gave the same error. Then, I again used diskpart and made a partition of 100 GB, tried to install, got the same error.
Then I removed the CMOS battery for 45 minutes and then put it back in and started the laptop. It went to BIOS settings and I set the correct time and then did diskpart again without any partition tried to install, got the same error message.
I really tried everything. Also, could this be possible because I am trying to install from USB stick? My DVD writer is not reading any CD's or DVD's, so I made a bootable USB following this link: USB Windows 7 Installation Key Drive - Create
So, could it be possible because of USB stick or that is not a problem? If not, what should I do now?
Please help me....
