The laptop has a 1TB HDD and a 32GB SSD set up raid 0. Windows boots in seconds. I created 3 partitions, one for windows, one for linux install and a 3rd partition for sharing stuff between both OSs. Problem, you guessed it, I booted fro the live CD and it would not recognize my windows install.
If you mean that you can't see any partitions on your disk, then the problem has nothing to do with EFI: This is a symptom of a damaged partition table. My suspicion in this case is that you've actually done a BIOS-mode install of Windows, which has created a new MBR partition scheme but left some unused GPT data on the hard disk. If this suspicion is correct, you can fix the problem with my
FixParts program. Once this is done, you should boot the Mint installer
in BIOS mode (by disabling EFI support in your firmware or selecting a non-EFI boot option for the installation medium). If I'm wrong in any of my suppositions in this line of reasoning, you'll need to be more precise: Describe the exact symptoms you're seeing and post the RESULTS.txt file you get when you run the
Boot Info Script from a Linux emergency disc. This will enable a better diagnosis of what's happening with your system.
I have been searching but my search criteria is returning too many results, (about 10K). If I have 2 physical hard drives, can I install windows 7 to one hard drive and mint to the other hard drive in a dual boot environment without jumping through uefi workaround hoops? If I install windows 7 to HDD1, will the live CD recognize my windows install and allow me to install Mint to HDD2?
Installing on two physical disks is certainly possible, but my suspicion is that you've jumped to an incorrect conclusion and that pursuing the solution you suggest will leave you with lingering problems at best or create new problems at worst. (This is not to say that you can't install on two disks, though; I'm just saying that attempting to install on two disks without fixing any problem you already have, and without understanding the BIOS- vs. EFI-mode boot of your current Windows 7 setup, is likely to cause additional problems.)
