"Reboot and select proper boot device"

  1. I just got new SSD - Transcend 128GB. Installed Windows. When I cold boot my PC -- from a shut off state -- I get this message before Windows loads: "Reboot and select proper boot device or insert boot media in selected boot device and press a key."

    However, if I press Ctrl+Alt+Delete and reboot I come into Windows.

    If I enter BIOS from cold boot, it does not detect my SSD. After rebooting it detects my SSD. Seems like the SSD is slow at firing up?

    I have run chkdsk and memory test without any errors.

    My motherboard is the MSI Z87-G55.

    Just installed newest BIOS, it didn't help.

    When I go into Board Explorer in BIOS it says SATA port 1 is empty. After reboot it says the same port is occupied by my SSD.

    Update: Plugged in another hard drive (non-SSD). Same rules apply to it. On cold boot, none of the drives are detected. After reboot, both drives are detected. I used a non-SSD as system drive before this, worked perfectly.

    Update: I have addressed this problem wrong. The error message comes because the BIOS wants to boot to a "USB Generic Device", afaik the device doesn't even exist. The real problem is that BIOS won't detect my SSD until I have rebooted 3-4 times. I will make a new thread, mods feel free to delete this.
