View Full Version : 12.042LTS using wubi.exe

First installed 12.10 64 bit with a problem. Removed it and installed 12.04.2, 64 bit, and came to the same problem. I did disable Secure Boot. When I Choose Ubuntu, I get a screen which reads: Windows Boot Manager Windows Failed to Start. A recent hardware or software change ... A file is missing. The file is \Ubuntu\winboot\nubildr.mbr :confused: What steps am I missing?

Wubi does not work on gpt partitioned drives or Window 8 that is pre-installed.
Grub4dos (which wubi uses) doesn't work with GPT disks (required by UEFI)

wubi only installs as direct download in Windows, not from CD with 12.04

How should I go about installing Ubuntu 12.04 or 12.10 to a drive with Windows 8 pre-installed?

Do you have Windows working? You need to fix that first. Then use Windows disk tools to shrink the Windows partition so you have unallocated space for Ubuntu to install into. Do not use Windows to create partitions as it may convert to dynamic which does not work with Linux.

Best to backup efi partition and Windows before install.

You will need to use the 64 bit version of 12.10 or 12.04.2 and from the UEFI menu boot the flash drive in UEFI mode. That way it will install in UEFI mode.
Systems need quick boot or fast boot turned off in UEFI settings. Vital for some systems. Best to backup efi partition and Windows partition first.
Use Windows Disk Tools to shrink Windows main partition, but not to create any new partitions, if installing on same drive.
As of 12.04.2, it is possible to install on UEFI systems with Secure Boot enabled (using signed versions of Shim, GRUB, and the Linux kernel). This is only currently set up for Ubuntu (desktop, alternate, and server) and Edubuntu images due to pressures of time; we expect to enable it across the entire Ubuntu family for 12.04.3. Details:
Installing Grub for UEFI secure boot is only possible if you have booted your system using EFI.
