My laptop came with Windows 8 on one drive and I installed a MSATA drive and installed Ubuntu on that. The installer setup a selection in grub for windows but when selected it goes to the following screen:

Windows failiied to start. A recent hardware of software change might be the cause To fix the problem....

I have seen several other posts with the same issue but they all seem to be how to accomplish this during the install. Since the install is complete at this point how can I correct it?

    do u have ubuntu bootable usb/dvd ?? – Deepen Sep 20 '15 at 12:43
  • I suspect that the windows boot part if looking for a path on the first drive. With the mSATA drive added that now has become the second drive. Which means that you need to edit the BCDstore – Hennes Sep 20 '15 at 12:44
  • I've had this problem before with GRUB and I'm pretty sure it happens because GRUB detects Windows as a legacy boot, when it's actually an EFI install. Have you run sudo update-grub yet? – TheWanderer Sep 20 '15 at 12:52
  • BIOS is calling the MSATA HDD2 and the drive with windows HDD0, Im guessing thats the issue do I just need change the device line in BCDstore from partition=\Device\HarddiskVolume2 to partition=\Device\HarddiskVolume0? – sealfab Sep 21 '15 at 12:54
  • Did you leave Windows fast start up on which is always on hibernation? That always causes issues. If UEFI you should be able to directly boot Windows from UEFI boot menu or one time boot key, often f10 or f12 check manual. And then maybe f8 to get into Windows internal repair console. If BIOS you just about need your Windows repair flash drive. Grub only boots working Windows, and Windows does need repair sometimes. Post the link from Boot-Repair for the Summary Report to show how you have installed and other details. – oldfred Sep 21 '15 at 14:35

Insert Windows DVD & go to boot menu & boot DVD. On Install page click on Repair. If this is successfully done, then insert Ubuntu bootable media (USB/DVD) & boot from it. Select Try Ubuntu. Then open terminal & type these commands.

sudo add-apt-repository ppa:yannubuntu/boot-repair

sudo apt-get update && sudo apt-get install boot-repair

Now, Press Windows Key type Boot Repair.

Click on Recommended Repair

Restart & check you should get dual boot option.
