Error related to EFI system..unable to install windows 7 64-bit
Hi,
I have Lenovo g580 which had DOS preinstalled in it {i5, 500GB, 4GB} and initially I had installed Win 7 32-bit on it. At that time, it gave some problem while rebooting 1st time, but i ran repair windows option and everything ran smoothly.
But the problem came when I tried to install windows 7 64-bit on the laptop using a DVD, no matter which drive I select, it does not allow me to go ahead. When I checked the details, I got the error message which is attached here.
There is no disk controller option in BIOS, nor is there anything related to UEFI systems.
i did r&d on UEFI systems, but i want to be sure of everything before i go ahead with anything.
Any help would be appreciated.
