    Problems with Windows Boot to SSD --fixed

    Hi folks I had a rare Windows problem that some might encounter with booting to Windows. On an older computer I didn't need the SATA DVD drive so what I did I connected two SSD's via a spliter - I've enough SATA ports on the mobo so that was fine. The two SSD's were a 500GB one and a 250 GB one -- the 250 GB one went through the DVD sata connector while the 500 GB one went through a spare Mobo Sata port. I installed Windows on the 250 GB one -- wouldn't boot unless I put the boot loader on the 500GB one - then it worked fine. Linux didn't care but I suppose Windows seems to know from the hardware if its booting from "an external" device or an internal one. Until I switched the SSD ports around I was getting errors as well like "Inacessible boot device etc". I swapped the SATA connections for the two SSD's and its working OK booting from the 250 GB SSD --- there's absolutely no problem power wise splitting the power from the DVD connector into 2 SSD's -- power drain on these is minimal !!!. I wanted the larger SSD for Linux and VM's . I only found out about this when using GRUB while it was "searching for other OS's". So if you do use the DVD port for SSD's on desktop type computers check that the SATA connector goes to a bootable SATA port on the MOBO that Windows can boot from !!! Weird error --might not be applicable on all systems - but Windows really does throw hissy sissy fits at times !!!!! Linux systems don't care BTW - you can boot from any device it finds a boot loader (GRUB) - even internal SD cards !! Cheers jimbo

  2. Unable to boot Windows after cloning it to SSD


    Thank you for writing to Microsoft Community Forums.

    I understand that you are facing issues while booting the PC after cloning Windows to new SSD. I would like to know what happens when you try to boot the PC to desktop using SSD?

    The reason you are not able to boot the PC is that the files required to boot Windows are still recognizing the HDD as the main drive. I would suggest you to try rebuilding the BCD files and see if you are able to boot the PC using

    Kindly follow the steps below to rebuild the BCD.

    1. Create a bootable media and boot the PC using the media.
    2. On the Install Windows screen, select Next >
      Repair your computer.
    3. On the System Recovery Options screen, select
      > Advanced options > Command Prompt.
    4. Now type in the commands and hit enter: BOOTREC /FIXMBR


      BOOTREC /scanos

      BOOTREC /rebuildbcd
    5. Restart the PC.

    If the issue persists, please get back to us with the results of the troubleshooting steps to assist you further.

    windows 10 slow boot

    I was having a slow boot issue on my Windows 7 install a little while back. It would take about 30 - 40 extra seconds to boot up for whatever reason.

    I would try following these steps, while this didn't solve my issue, it did increase Read/Write to where it should be.

    Looks to be similar to this:

    In the end, I had to reinstall my Windows 7 entirely to fix the booting issue. It was taking around 35 seconds to boot, and after the fresh install it takes about 7 seconds to boot.

    Problems with Windows Boot to SSD --fixed

    Booting/Fixing Windows 10 Disk.

    The easiest/most reliable way to fix Windows boot problems has historically been Macrium Reflect's Fix Windows start problems utility. Probably the easiest way to make it is to make a bootable USB flash drive or DVD of Kyhi's recovery tools:
    Windows 10 Recovery Tools - Bootable Rescue Disk

    Boot into his recovery tools, run Macrium Reflect, under the restore menu will be the utility to fix Windows start problems. You will get a list of Windows installations that it finds then in the next step you will get a list of bootable partitions available for Macrium Reflect to fix.

    You can also install Macrium Reflect free - but the fix Windows start utility is only available when you actually boot the computer from a Macrium Reflect rescue drive with Windows PE:
