Error related to EFI system..unable to install windows 7 64-bit on lenovo g580..

2013-01-14, 8:55 AM

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 tto 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.

Thanks for no help guyz!

but i found a way..so for anybody else out there..here is the solution..

 

  1. When installing at the partition screen hit Shift+F10.
  2. At the prompt type diskpart and press Enter.
  3. Type list disk (Not the number of the disk you want to use)
  4. Type select disk X where is X is the number of the disk you want to use.
  5. Type clean. This will erase all the data on your system.
  6. Type convert gpt
  7. Now reboot the system with the DVD/USB, and you will see only Unallocated Space. Use that to install the new windows.

Be warned though, this will clear out the partition table on the drive; make sure you have a backup before attempting this if you have important data

I have a question, if I clean all the disk I'll loose the OEM partition, so I loose the laptop warranty, is there any way to modify only the partition for the windows?
