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 missingmessage
- 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 ?
