Can anyone help me to figure out why I cannot get Windows 7 x64 to install on my Lenovo Flex 2-15. I have turned secure boot off, enabled legacy mode so that UEIF don't get in the way. It boots up to the install screen and then the USB drive goes off. I'm using a Sandisk Cruzer 8GB flash drive and then light completely goes off when it hits the install screen. I continue to have the "Load Driver" error and nothing will show up if I even try to browse for this driver. I can't understand what is going on because I can put the flash drive on my desktop pc and it boots up to install fine without this error.

From Resolving the dreaded Windows 8 0xC0000225 error :
I've had this happen to me twice, all of a sudden Windows 8 refuses to boot and gives an error code of 0xC0000225 (or something) and anything you do won't fix it. The problem is that since for whatever reason Windows thinks there's no bootloader, it refuses to boot. Period. You can't even go into the recovery environment, which is my biggest complaint at Microsoft.
In any case, there's one way I've found to resolve this. If you have access to another computer, take out the affected computer's primary drive and find a way to mount it in the system (internally, externally, whatever). Then do the following:
- Open command prompt as an administrator
- Type in "diskpart"
- Type in "list disk". Find out which disk the affected drive is.
- Type in "select disk #", where # is the affected drive's number
- Type in "list partition", find the partition number of the system partition (it's usually 100MB, 200MB, or 300MB), then type in "select partition #", where # is the system partition's number.
- Type in "assign letter=z", assuming you don't have a Z: drive.
- Exit out of diskpart by pressing CTRL+C
- Type in BCDBoot
[Drive letter of affected drive's Windows partition]:\Windows /S Z: /F UEFISo if the affected drive's Windows partition is say G:\, you would type in BCDBoot G:\Windows /S Z: /F UEFIIt should fix the bootloader. If you can get into a recovery environment on the affected computer, then this should work as well.
This new UEFI boot scheme is very confusing, I know. Fortunately with the latest Lenovo laptops you don't need to disable secure boot, nor do you need to disable fastboot, nor do you need legacy mode. You don't need any of that. At least for Ubuntu 12 and up.
Please put it back. :-)

The only thing that excellent answer does not address is how to get to the point of booting from USB stick, on your Lenovo. The trick (I happen to discover this all by myself, simply by noticing an option not available in other instructions sets):
[Shift]+Restart > Use USB Devices > USB Stick

I've had the same problem on my Lenovo Flex 2 15 when trying to install Windows 7 (it's shipped with Windows 8.1)!
In order to boot up on an USB in the first place, you need to push the "Novo button" (in reality a pinhole) on the right side, almost up front. This will show a list of four options; choose "BIOS Setup".
In the BIOS under the tab "Boot":
Under the tab "Configuration":
Under the tab "Exit":
Finally, to be able to proceed beyond the error on "missing driver for CD/DVD/USB" once the setup has initiated, I put the driver for USB (it only exists for Bay Trail-M architectures, but I have a Haswell (i5-U4210) and included it for safe measure), the Intel Chipset Driver and the Intel Management Driver for W7 64-bit in the root of the bootable USB-device (only the Haswell-version of these).
Subsequently I was able to install W7 Pro 64-bit successfully.
