I've recently set up a successful install of Mavericks 10.9.1 using a *certain* USB loader on my Lenovo IdeaPad Z500 Touch, with everything configured to work correctly bar the built-in WiFi, touchscreen and onboard nVidia GPU.
However, while everything is running smoothly on the Mac side of things, my pre-installed copy of Windows 8.1 no longer boots from Chimera, notifying me that my boot configuration data is missing.
I've pondered that the boot loader I'm using is pointing to the wrong boot partition (rather than the drive which stores Windows that Chimera has detected, along with my Lenovo recovery partition)...
However, I'm guessing that my problems may boil down to UEFI, having changed my BIOS settings to Legacy prior to installing Mavericks. I also had to disable Secure Boot to avoid any further issues.
Would it be worth reconfiguring my BCD file using Windows 8.1's advanced system recovery, or would that then lead to more problems?
Additionally, is it too late to change my boot loader to Clover? I've read that Chimera doesn't support UEFI, but surely I wouldn't receive a BCD error if my Windows partition wasn't detected... Conversely, it may be why I cannot find my System Reserved partition.
Obviously, any reinstallations to get my dual-boot config in working order would be my last resort, which is why I'm very hopeful that I'm not the only one to have fallen into this issue. It's taken a lot of time to perfect my Mavericks install!
Many thanks for your help in advance. Feel free to ask for any screenshots or further info
