How to fix No Bootable Device Toshiba Laptop?
What is No Bootable Device Toshiba Laptop?
No Bootable Device Toshiba Laptop is an error that happens due to unstable BIOS settings. There could be a concealed MBR field in your laptop and it may affect the operating system files and drives that are necessary for running your laptop. This error message means that the operating system of your machine does not recognise the bootable hard disc. The comparatively recent type of issue introduced by the broader introduction of solid-state drives (and other drives with more complex power specifications than traditional mechanical hard drives) is the identification and compatibility of the disc. This refers in particular to the sleep/resume and cold boot detection of these machines, which are often not detected at all on individual systems. Occasionally, a BIOS upgrade on the device or a firmware update on the drive will fix the problem, but the drive may be unstable at other times.
I’ve seen this most recently with Critical brand SSDs, which have proved to be of tremendous value—when they operate. Reliability has not been an issue with the drives that I have bought for my customers, but often the identification of the drive is a challenge. Specifically, some of the newer Dell Latitude laptops (of which I buy and service quite a lot) seem to be grappling with Critical SSDs.
The message you will see on a Toshiba Laptop if this happens to you is:
No bootable devices found.Press F1 key to retry boot.Press F2 key for setup utility.Press F5 key to run onboard diagnostics.
Interestingly, if the user presses F1 to retry, the machine then boots normally. This indicates that the problem has to do with the machine not detecting the drive quickly enough during POST to continue with the boot process.
With other machines, the problem can be resolved by switching ON “Hot-plug support” (or similar) in the BIOS Setup. However, this option does not exist within Dell’s BIOS Setup.
So, then, what’s the solution? Actually, it’s precisely the same thing I posted in my previous update as a response to a completely different problem: bypass the RAID controller and use AHCI interface instead. The problem apparently seems to be related, at least in part, to how the system processes the communication between the drive and the chipset via the Intel RAID controller. Disabling RAID does require jumping through a couple of hoops, but it’s relatively quick and easy. See my post here for full instructions!
Once this is complete, the machine boots normally each and every time!
