    Ubuntu and Win 7 partitions new install

    Hi there,

    I have a Windows 8 laptop which is frustrating me no end. Windows 8 frustrates me and I hate this secure boot nonsense.

    I'm going to be installing a copy of windows 7 over it, but when I look at it there are about 10 partitions in all (its a lenovo).

    I want to be able to have a 100GB Win 7 Partition, and then install Ubuntu straight after it.

    I want to split up the remaining 400GB between an Ubuntu partition and then a storage space for videos and files etc, which Win 7 can access.

    My question is, do I need a boot partition when putting Win 7 on there to be able to dual boot, ie:

    Boot 1000MB
    Win 7 100GB
    Ubuntu 20GB
    Home 50GB
    Swap 4GB
    Storage 300GB

    Or something like that?? What would you suggest?

    Thanks

    Can you disable secure/fast boot in your bios and enable legacyboot?

    nope i put my /boot/ in my "ubuntu" drive. you just have to link it to your MBR with grub.

    # sudo mkdir /mnt/boot
    make empy mount directory

    # sudo blkid
    display disk partitions

    # sudo mount /dev/sdXY /mnt/boot
    where X is the letter of the drive and Y is the number of the partition containing the boot/

    # sudo grub-install --root-directory=/mnt/boot /dev/sdX
    notice there is no Y at the end of the previous line.

    this can be done from a live cd




    if you end up at a grub prompt on boot. set root. specify kernel, specify initrd. perhaps tweak parameters. boot and update-grub.
    grub>
    #ls
    #ls (hdX,Y)/
    #ls (hdX,Y/boot/
    #linux (hdX,Y)/boot/vmlinuz-<somethingheremaybe>
    #initrd (hdX,Y)/boot/initrd-<somethingheremaybe>
    once you get it running
    #sudo update-grub.

    I have some followup questions before I answer yours.
    1. Does you computer boot in EFI mode? I suspect it does.
    If it does boot in EFI mode then you will need a 500mb FAT32 partition with 'boot' flag.

    If you have a Ubuntu DVD/USB then boot with it and 'Try Ubuntu without installing". Open Terminal [Ctrl + Alt + T], run the following commands and post its output here:
    Code:
    sudo parted -l
    sudo fdisk -l
    The output will tell us what you have and we may help you further.

    You have to decide if you want to keep the current gpt partitioning that Windows only boots with UEFI or convert to the 30+ year old MBR(msdos) partitioning with both Ubuntu & Windows only boot with BIOS boot mode.

    You can convert a Windows 7 DVD that only installs in BIOS mode to UEFI.

    If you let Windows install in BIOS mode over gpt, it only converts the primary gpt partition table. One advantage of gpt is that it has a backup, but Windows leaves that and then Linux sees both MBR and gpt and gets confused. You have to then remove backup gpt table.
