This question already has an answer here:

I would like to install Ubuntu on my computer (v12.04) replacing a previous Windows OS.

Taking into account the following

  • My HDD has been formatted using the Windows Disk Managament utility (right-click, format)
  • When I turn on the PC I have the BOOTMGR is missing message
  • Cannot boot from CD/DVD as the drive isn't working correctly
  • Cannot boot from USB as the option is not available.

How can I install Ubuntu via the HDD knowing that the only way I can access it is to remove it and put it in an external USB HDD case ?

This question was marked as an exact duplicate of an existing question.

Do you have access to another PC that is bootable from a CD or USB? If so, you could move the drive to that PC and install Ubuntu on it there and move it... – Kendor Feb 10 '14 at 13:25
Yeah, if I remove the HDD I can access it via USB on a Laptop. Is it just a normal install on the USB mounted HDD then? Will the initial PC boot properly with Ubuntu if I just plug the HDD it back in afterwards? – DWryly Feb 10 '14 at 13:32
See if this works: You need a working windows for this though. – Rinzwind Feb 10 '14 at 13:52
Yes, you can install to USB mounted externally... just be careful about your target.. – Kendor Feb 10 '14 at 14:54
I actually installed an earlier version of Ubuntu that way. And it worked correctly. – Erkin Alp Güney Feb 10 '14 at 19:37

You can put the Ubuntu installation iso's contents on a partition on it's own and boot from that partition! looks like that wouldn't work.

the other idea is installing Ubuntu on the HDD through your working windows computer.

make the live DVD as described here:

Connect the HDD to the computer and boot from that live DVD. some description here

Ok, so I create a partition in Windows, and simply copy the downloaded ISO to the partition? – DWryly Feb 10 '14 at 13:46
No that won't work! – Roy Samuel Feb 10 '14 at 13:55
You need to use another computer and the iso image to do this. 1) in case if the second computer is windows, you can use an utility like "unetbootin" to make your formatted HDD bookable using the iso image. 2) in case the second system is Linux, you can use "create startup disk" to prepare the formatted HDD as a Linux installation drive. – Roy Samuel Feb 10 '14 at 14:00
The reason this does not work is that you at least need GRUB installed to boot the ISO. @RoySamuel it is possible to do with 1 computer and a working windows: you can change a wubi to a normal ubuntu and then remove the windows you used to unstall wubi/ubuntu – Rinzwind Feb 10 '14 at 14:08
Ok, thanks guys. I'll try that tonight without and then with unebootin if necessary. – DWryly Feb 10 '14 at 14:31

Check my comment, for instructions. From the Bios menu, choose the second HDD to boot from. Hope that helps.
