I switched the SATA Control mode<\/em> from IDE to AHCI<\/strong> after installing my new Samsung Evo 850 SSD on my Gigabyte Z68AP-D3 board.
\nThis resulted in an unrecoverable halt of the system prior to grub execution and the following error message:<\/p>\n

Loading Operating Systems\r\nRead Error<\/pre>\n
My Setup<\/h2>\n
SSD: Samsung Evo 850 SSD, firmware: EMT02B6Q (latest)
\nBoard: Gigabyte Z68AP-D3, BIOS: F8 (latest)<\/p>\n
Possible workaround for the read error<\/h2>\n
I did some research and found other people to experience the same problem. They came up with a small workaround<\/a>.<\/p>\n
    \n
  1. Remove any medium from your CD\/DVD drive<\/li>\n
  2. During boot open the Boot Menu<\/em> where you are able to select a different start option such as boot from CD\/DVD, USB etc.<\/li>\n
  3. Choose booting from CD\/DVD<\/li>\n
  4. Your system might be able to boot now<\/li>\n<\/ol>\n
    Unfortunately this did not work in my case.<\/p>\n
    First possible solution<\/h2>\n
    The same person later came up with a solution<\/a> that worked for him\/her.<\/p>\n
      \n
    1. Enter BIOS<\/li>\n
    2. Go to Integrated Peripherals<\/em><\/li>\n
    3. Change Onboard Serial Port 1<\/em> from 3F8\/IRQ4 to auto<\/strong><\/li>\n
    4. Reboot<\/li>\n
    5. Your system might be able to boot now<\/li>\n<\/ol>\n
      This did not work for me either.<\/p>\n
      Second possible solution<\/h2>\n
      I did some additional digging and found another person<\/a> with a problem that might be the same as mine or at least similar. However the solution they figured out<\/a> was the one that solved the problem in my case<\/strong>.<\/p>\n
        \n
      1. Enter BIOS<\/li>\n
      2. Go to Advanced BIOS Features<\/em><\/li>\n
      3. Change Quick Boot<\/em> from enabled to disabled<\/strong><\/li>\n
      4. Reboot<\/li>\n
      5. Your system might be able to boot now<\/li>\n<\/ol>\n
        I have yet to figure out what’s the exact source of the problem and if there’s a better solution which does not involve disabling quick boot. On the other hand, I couldn’t notice any major delay due to this change. My guess would be that the SSD takes too long to initialize during startup. A firmware update via Samsung Magician could not help. If you can provide some insight feel free to leave a comment.<\/p>\n","protected":false},"excerpt":{"rendered":"
