  2. Greetings my fellow hackers! I've run into a bit of a conundrum. I've recently created a Mavericks installation usb, i'm trying to upgrade from Mountain Lion 10.8.3. I installed Clover as the bootloader on the usb, and spent all of last night until i realised that i missed the USB 3.0 driver, solved that thank God. Now however, it seems like my current hurdle is the message "This disk cannot be used to start up your computer" when i try and select the partition/drive i want to install Mavericks to. I've read around and it seems like the suggestions everyone gives is to shrink the targeted partition slightly (1Gb) with disk utility, and try again. I've tried this, and am still getting the same result. The other suggestion i've read is to format the whole drive clean and then try to install. My goal however is to do an in-place upgrade without losing files and already-installed apps, especially since i don't have access to another hackintosh, legit mac, or computer capable of booting into the installer to fresh install (originally installed ML with this latter method). A clean install is going to be my last resort, and i actually don't think i'd have that many issues this time around. Clover boot manager seems to have prevented the issues i usually have with my limited access HP BIOS settings. I'm looking at you HP engineers and project managers HP Envy 17t-32XX 3D CTO | i7-3820QM | AMD Radeon 7850m | 8Gb Ram @ 1600Mhz | Windows 7 on 750Gb drive (removed during installation attempts)| OSX 10.8.3 Mountain Lion on secondary

    AMD Radeon HD Mobile Graphics

    I have successfully installed mavericks on my laptop, It boots up fine and I can login etc. But the graphics aren't working and the resolution is locked to 1024x768. Also, The Speakers and the click on the trackpad don't work, but they are less of a worry. Hope Someone can help! My Specs.
