    Re: Forcing System boot up

    Are you using the correct UUID in Boot stanza. The example just has some old UUID.

    You need to be using this:
    Code:
    Device           UUID                                   TYPE       LABEL
    
    /dev/loop0                                              squashfs   
    /dev/sda1        14283BD5283BB518                       ntfs       SYSTEM
    If booting another drive, not sure if you need drivemap command or not. You may need to experiment.

    Re: Forcing System boot up

    I lack the knowledge to work at the command level. All my support was without using it in the past.

    It is like being able to read another language because you know the letters but none of it makes any sense.

    It is too bad that you are not here with me to show me the way as I know you could find a solution easily.

    Nothing that I try seems to work and that is due to lack of knowledge in the matter.

    I think the only way for me to solve it is to copy someones else work on the exact request but I can't find.

    Do you think you could right 10 possible codes that you would think should work based on the info that you have already. I can provide more if you require it.

    Thanks

    Re: Forcing System boot up

    Project has been completed!

    I installed Grub from the below link onto a USB and It was able to see the OS and it booted.

    HDD bootup is enabled from BIOS.

    Boot partition is inactive.

    So now system only boots if the USB is flash disk is plugged in and I choose the boot for windows.

    The link for the Grub I installed for this project is.

    https://sourceforge.net/projects/supergrub2/

    It works only when the Generic MBR is installed from the Boot-Repair-Disk.

    Re: Forcing System boot up

    A new update on the above method solution to boot windows only if USB is plugged in.

    Windows Hibernate will not work anymore because the Windows partition is made in-active in order for that to work....

    Windows Sleep still works.

    They are not the same....

    New Update!

    Hibernate will not work because volume is set to inactive.

    Sleep still works but it is not the same thing.

    Your solution did work at the end on Win 7 which is running on an old Laptop using legacy support BIOS.

    I am unable to get it to work on a newer Laptop running Win8.1 on UEFI BIOS settings.

    Can you give some tips here too?

    Re: Forcing System boot up

    Start a new thread with details including make/model & video card of newer system.
    And what version of Ubuntu & Windows.
    And post link to summary report.
    Be sure to include computer & issue in title.
    If I do not see it in 24 hrs, you can PM me link to thread, but I see most threads that I may be able to help on.

    Re: Forcing System boot up

    I am the thread starter in this one and it is the same issue and you are the one that solved it last time. It is just a different O/S.


    I can add details here rather than starting a new thread.

    Is that ok with you? Or do you insist on starting a new one?

    Re: Forcing System boot up

    If a different system, I prefer a new thread.
    Plus this thread is older, things change.

    Re: Forcing System boot up

    Ok No problem.

    For other visitors. you can find it working well on legacy support Motherboards with the below solution.

    ______________________________________


    • I installed Grub from the below link onto a USB and It was able to see the OS and it booted normally after selecting it from the Grub menu.

      HDD bootup is enabled from BIOS.

      Boot partition is inactive. This can be done from Diskpart in CMD while logged in. But do not reboot without the USB being ready with Grub on it. It will show that operating system is missing at which point you can continue to booting to the O/S from the USB Grub menu.

      So now system only boots if the USB is flash disk is plugged in and I choose the boot for windows.

      The link for the Grub I installed for this project is.

      https://sourceforge.net/projects/supergrub2/

      It works only when the Generic MBR is installed from the Boot-Repair-Disk. SO after booting into Boot-repair disk just run a repair and it will install the needed files for this solution to work then exit the program.

      Download Boot-Repair-Disk from

      https://sourceforge.net/p/boot-repair-cd/home/Home/

      You can also use the boot repair disk to get it back to working normally. Then the Win O/S will go back to booting normally. So if you can't get this solution working then just boot from boot repair disk and do a repair and restart the system and Windows will load normally again.

      Use Rufus to create the 2 USB flash disk for the Grub menu and the Boot repair disk. It sometimes needs to connect to the internet to add needed files.

      Link is: https://rufus.ie/

      Important notice!

      Windows Hibernate will not work anymore because the Windows partition is made in-active in order for that to work....

    • Windows Sleep still works.
