Problem setting SSD as boot drive

[Josh2037]

So, here's the situation.

I installed a Samsung 850EVO SSD 250GB today, cloned a fresh install of windows 10 to it using the Samsung migration tool, I then realised my bios sata setting was set to IDE so I switched to AHCI and I get the error message: UNACCESSIBLE_BOOT_DRIVE. Setting it back to IDE works and is how I am using my computer right now.

The SSD is the only drive connected right now.

I have tried this method: http://www.tenforums.com/performance-maintenance/15006-attn-ssd-owners-enabling-ahci-mode-after-windows-10-installation.html

Still UNACCESSIBLE_BOOT_DRIVE

Any help would be appreciated

If it had been set at IDE mode, you are probably stuck with it even with the new drive. To use the better AHCI mode, you will need to set the BIOS to AHCI mode and uninstall the OS from scratch. I encountered the situation few years ago.

That's awesome. I learned something new today.

[strike][strike]Set it to IDE in bios, boot and edit the following reg-entry: (I did this on 8, but should work on 10 to too, to make sure, open PowerShell and type "REG QUERY HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci" that will output the value.

(RUN regedit)

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci

Set the value in MSAHCI to 0 - that should enable the ACHI-driver and let you boot when you set BIOS to AHCI

solved further up

Though I'm pretty sure you only need to edit this key - googled and microsoft says so too.
