I bought and installed a brand new 120GB OCZ Vertex 2 SSD onto a spare Sata port and bought Paragon Migrate OS to SSD http://www.paragon-software.com/technologies/components/migrate-OS-to-SSD/ My current system/boot drive HDD (a 750GB 7200RPM Samsung) has only 60GB used on it (I've cleaned it right up) running Windows 7 Ultimate 64 bit. Migrate OS to SSD runs "perfectly" as far as I can tell and (it completes/finishes) and then requiring a restart and advises to make changes to the boot order in the Bios (which is a good thing to advise - makes sense ). I restart booting off the SSD (even unplugging the old drive) however it comes up with the following Windows error: "Windows failed to start. A recent hardware or software change might be the cause. To fix the problem: 1. Insert your Windows installation disk and restart your computer. 2. Choose you language settings, and then click "Next." 3. Click "Repair you computer." If you do not have this disc, contact your system administrator or computer manufacturer for assistance. Status: 0xc000000e Info: The boot selection failed because a required device is inaccessible." I have tried twice with the same result both times - even completely unplugging the original HD so that the only disk available to boot from is the SSD. Appreciate any advice. Obviously it's failing when trying to boot off the new SSD. I'm really not interested in losing this install of Windows for the benefit of an SSD so was hoping the clone would work as easily as other clones I've done over the years with normal HDD. I can access the SSD as a drive from windows if I format it and treat it as a normal drive in Windows and/or see the cloned data on the SSD just as a drive. Any ideas? Unfortunately I don't have another PC I can test the SSD on as a boot drive easily.
