Lenovo G500 failing to install 7 in Dual Boot with 8

I've just had a new Lenovo Core i5 g500 arrive to test during Best Buy's 2 week return policy period. I've shrunk C, updated to latest BIOS, reset BIOS Boot tab to DIsable Secure Boot, UEFI choice. I then can only get into BIOS menu via Windows 8 Advanced Startup settings since no hotkeys respond, choose UEFI Flash stick to boot, this message flashes: "EFI device has been blocked by current Security policy."

So I reenter BIOS through 8, change to Legacy Support with UEFI First boot. When I reboot into BOot choices it shows the Kingston USB2 stick in both UEFI and Legacy boot choices. I choose UEFI and it gives the missing driver error. Can't choose Legacy because it would want to delete and reformat as MBR.

Before on an Asus discussed here http://www.eightforums.com/general-...8-laptop-arriving-wish-dual-boot-seven-2.html I made the Paragon 12 boot disk to image entire HD before wiping to install 7 but it wasn't necessary because I was able to install in the shrink space even though 8 wasn't bootable (a great position to be in). Is this possible on Lenovo? Anyone?

Got it. Somehow the Rufus flash stick installer had gone bad as proven when I tried it in another UEFI machine. I reformatted it and was able to install in Legacy with UEFI First.

Once other weird thing is that the latest Lenovo BIOS kept changing back to Secure Boot after each attempt, as though it recognized I hadn't installed another OS and was re-securing 8. Now we'll see if it does it again after Win7 boot up, and if 7/8 can each boot under Legacy.

You need to see if there is an option in the Bios for the CSM (Compatibility Support Module) to be enabled. This is more important for booting Windows 7 than the Secure Boot setting, which usually only sets the system to UEFI only boot.

Win7 runs great on this Lenovo G500 which I'm glad to say I am keeping, after trialing similarly a dozen other laptops over the past two years on Best Buy's 14-day return policy. This one is flawless, after resolving palm-drag causing cursor to skip by installing Elan gesture driver (only) and then on its Mouse tab selecting "Disable touchpad when USB mouse detected."

Will soon wipe the Windows 8 phone app off the drive to resize Win7 into its space. I am trusting that Partition Wizard means it when they say they support UEFI. :think:

Doubling RAM to 8gb using Kingston Model KTL-TP3C/4G System Specific Memory - Newegg.com. Note that if you open a case with Kingston Tech Support and are advised the part number for their superior OEM RAM, they will refund/replace it at their cost if it doesn't work no matter where you order it besides eBay.
