I have an HP Pavilion that came preinstalled with Windows 7. I upgraded to Windows 10. The computer has an internal hard drive and an external usb hard drive. When I try to install Ubuntu, it will NOT let me install on the internal hard drive, only the external. A drop down menu is there, but when I click on it the only option is for the external drive.

I installed it on my external drive and now it will not boot Windows nor Ubuntu.

Edit: In a moment of desperation, I created a Windows10 installation on USB. From there I was able to get into command prompt and run some repair and now Windows 10 boots properly.

I can still boot from the USB to the try Ubuntu.

I reformatted the external drive and tried again and the message I get is that there are MULTIPLE operating systems and do I want to install Ubuntu along side them. If I install along side, I still can only do it to the external drive.

I'd like to save the data and programs on my internal HD. How can I get Ubuntu to install on my internal drive.

Before trying to install, I created an unused partition on my internal HD. When I go to "do something else" during installation, I am presented with what I THINK is the partition table for my internal HD, but the partition I created shows up as unusable. I'm willing to have a go at trying to partition and install Ubuntu that way (it that would work), but that is oustside my comfort zone without some good directions.

  • Welcome to Ask Ubuntu! :-) The first part of your question (How to repair Windows) is better asked on SuperUser, a sister site to ask Ubuntu... – Fabby Apr 24 '17 at 7:00

    @karel: edited that in now. L.D. Dewees: we need more info, can you boot by using "try Ubuntu" and provide us with the text of the output of parted --list. Please add that info to your question by editing it and providing a concise status of your current situation... :-) – Fabby Apr 24 '17 at 7:13
  • Please run the Boot Repair utility and select the "Create BootInfo Summary" option. (DO NOT click "Recommended Repair," at least not yet!) When asked whether to upload the report, click "Yes," and then post the URL provided here. This will give us more details about your configuration, which is required to base an answer on more than guesswork. – Rod Smith Apr 24 '17 at 20:52

During reboot, can you enter a key to boot into Windows Recovery Mode to Repair Windows 10? If not, you need a Windows 10 Recovery DVD/USB. One from Windows 7 might also work. It you can't repair Windows, you have no option but to save your data via the Live CD to the external disk (or another).
Let me know if the repair was successful, then we can figure out why the install Ubuntu to the internal disk fails.
Good luck

  • I was getting an error similar to device not found. While searching for answers, someone suggested using Lilo to get my WIndows boot option back. When I ran Lilo, I now get a bootmgr not found error. I'm hoping that is progress. I tried getting into Recovery mode and tried a Windows10 installation disk but both give me the same bootmgr not found error. – L.D. Dewees Apr 23 '17 at 20:38
  • I'm afraid it only confirms what I wrote, you need to perform the repair action. That should repair the bootmanager and let your Windows boot again. – user680858 Apr 23 '17 at 20:42
  • In a moment of desperation, I created a Windows10 installation on USB. From there I was able to get into command prompt and run some repair and now Windows 10 boots properly. Not sure why it wouldn't boot from the CD, but that's probably a Windows question. Thanks for your help. Any thought on where to look or what to do about not being able to install on the internal hard drive? Should I ask that as a separate quesion? – L.D. Dewees Apr 23 '17 at 22:56
  • Congrats on having a working Windows again. No, a new question is not necessary, not yet at least. Please tell me the state of the machine and internal disk at the moment you started the Installer. Does the machine boot using Secure Boot (I had to switch it off when I installed Xubuntu alongside my Win8.1), is it using UEFI (then you must select UEFI boot for the Live CD), how many physical and logical partitions are on the disk, was there at least 20GB unallocated space available on the disk. When you are in Live CD, issue: sudo fdisk -l – user680858 Apr 24 '17 at 8:56
  • Having written the previous, I had a thought and I want you to consider another solution. One that I am using to great satisfaction. As you have an external disk available, why not install VMware Player in Windows and install Ubuntu as a VM and storing its files on the external disk? I have a laptop with 2 disks, the 2nd one in a DVD-caddy adapter. The 1st has Win7 with Xubuntu as a VM which is stored on the 2nd disk. The second boots Xubuntu and has Win7 as a VM which is stored on the 1st disk. – user680858 Apr 24 '17 at 9:13
