r2d2picachu Posted June 13, 2013 Share Posted June 13, 2013 Hey Everyone, So I got Mountain Lion to install.... and i can't get one big thing to work.The bootloader... it just wont boot without the DVD at all. It gives the error operating system not found if i don't put the DVD in first. I thought it might be because i have a 4K hard drive sector thing (it was a 1TB hard drive) but i switched it for 500GB WD hard drive. Still no luck, i've reinstalled a million times, tried every single bootloader installer, maunally installed the bootloader as well but no luck. I'm running only OS X Mountain Lion, no other OS at all.Please help out with thisThank You!Specs: Intel Core i3 Processor 2.2GHz 6GB DDR3 RAM (Had this hard drive) 1TB 7200RPM Hard Drive; now i have 500GB western digital 7200RPM 24-Inch Screen, Intel HD Graphics 3000 It's an all in one computer by the way, & the computer is a vaio vpcl231fx is that helps Link to comment Share on other sites More sharing options...
marl Posted June 13, 2013 Share Posted June 13, 2013 What partition scheme you use? is it GPT, MBR or something...? Since I don't have much experience on laptop, does your laptop support EFI boot? Link to comment Share on other sites More sharing options...

If your rig support EFI boot or GPT. It would be easier to booting up. CMIIW You can check it in your BIOS configuration. Link to comment Share on other sites More sharing options...
