    Boot Repair Question


    I have been playing around with linux and running Ubuntu 12.04 LTS off of a live USB drive. Before, when I turned on my system, it would go to the purple screen and then ask me if I wanted to use Windows 7 or Ubuntu.

    The other day, in Ubuntu, I was updating all applications and maybe the OS as well. It told me that I had to reboot to finish. Now, with the USB drive plugged in, the computer goes straight into Windows and never asks me if I want to use Ubuntu. I'm currently downloading a live CD that includes boot repair.

    My question: what are the chances that bootrepair will do something to mess up my Windows install? From what I read, bootrepair defaults to installing the Grubs onto every disk. Shouldn't I only need it on the USB drive? I've had enough problems with this sort of thing before that I don't know if I trust bootrepair to not screw up my Windows system disk or my data disks.

    You need to clarify what you were doing. If you were using a Live CD on a flash drive it is a read-only system and can't be updated/upgraded. Did you use it to install Ubuntu to your hard drive? Did you have it set up with a persistence option? At the very least you will need to post more info on your drives/partitions as well. Use the fdisk -l command to do that or go to the site below and run the bootinfoscript. You will need to use a Linux system but it isn't clear if you are able to boot Linux:

    Thanks for the feedback. When I was running Ubuntu before, I was doing it from a live USB that COULD be written to (not read only). I have no idea what a "persistence option" is so I can't tell you about that.

    I have a bunch of hard drives, but they are all in "fakeraid" arrays and I was never able to access their data while in Ubuntu, which is why I always ran it off a live USB.

    Other than that, I can't get into linux right now until I have time to burn a new live CD. I will report back with the fdisk -l results when I do. Maybe this is enough info to provide some clues though?

    fdisk -l

    Below is the result of fdisk -l.

    sda: 64GB SSD (Windows cache drive)

    sdb & c: 320 GB hard drives in fakeRAID 0 - This is my Windows system disk

    sdd & e: 2 TB hard drives in fakeRAID 1 - contains all my data

    sdf: 16 GB USB drive that used to work for using Ubuntu until the update broke it

    sdg: 1 GB USB drive that I only used to save the fdisk -l report (I usually don't use it)
