    Re: Partitioning and Dual Boot

    I dropped this project for a while, I'm now just getting back to it

    Code:
    sudo parted /dev/sda unit s print
    Gives me
    Code:
    Model: Unknown (unknown)
    Disk /dev/sda1: 409600s
    Sector size (logical/physical): 512B/512B
    Partition Table: loop
    
    Number  Start  End      Size     File system  Flags
     1      0s     409599s  409600s  fat32
    What does that mean?

    That changes a lot of things. Both Windows and Ubuntu have to be installed in BIOS/MBR or UEFI/gpt modes. When booting a 64bit liveCD you should get two choices on booting - UEFI/efi and BIOS/legacy/AHCI or whatever your system calls it.

    So is system UEFI.

    Post this from liveCD.

    sudo parted /dev/sda unit s print

    If first partition is efi and drive is partitioned with gpt then Windows is in UEFI mode.

    Re: Partitioning and Dual Boot

    Your post #12 is only showing the flash drive as sda, but Boot-Repair showed main hard drive as sda. Some systems may mount flash as sda.

    Have you backed up your Windows partition and the efi partition? Must do this.
    Have you made a Windows repair flash drive.

    Have you used Windows to shrink the Windows partition, but not to create new partitions? ReBoot Windows several times to make sure it runs chkdsk and makes whatever repairs it wants based on new size.

    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:

    Re: Partitioning and Dual Boot

    Wow, this is getting complicated.
    Maybe I should just format the whole drive, and start from scratch.
    - Format all
    - Create partitions for Data, Ubuntu, Windows and begin by installing Windows

    I have my data backed up I have the EFI partition backed up (is that the recovery partition?)
    I have a W7 rescue CD I made a W7 install-from-USB DiskOnKey
    I also have a USB DiskOnKey with Yummi MultiBoot with a few distros and recue disks.

    Re: Partitioning and Dual Boot

    Somewhere I read the Windows was not offering new drivers for Windows 7 to use with any new hardware offered with Windows 8. So your Windows 7 may not work.

    Windows 7 may install in non-secure boot mode but will not ever work with secure boot.
