    Deleted all Operating Systems, how do I install Windows 7? (USB)


    So I had Ubuntu, when I installed it I accidently overwrote windows.

    I tried to get it back now but I think I messed up badly. I formatted /sda1 as NTFS and deleted Ubuntu.

    I have live Ubuntu on a USB & Windows 7 on another one. How do I install windows 7 back? At the moment I'm using a live ubuntu USB as I have nothing else to use. When I go on gparted, these are the main things that show.

    Partition:
    /dev/sda1
    /dev/sda2
    /dev/sda5
    unallocated

    File System:
    ntfs
    extended
    linux-swap
    unallocated

    Size:
    462 GIB
    3.75 GIB
    3.75 GIB
    1.02 MiB

    /dev/sda1 has the flag: Boot

    That's all that's on there. I hope someone can help me! *Smile

    :)

    I deleted my operating system

    I accidentally deleted my operating system by I was trying to reset my computer and permanently deleted everything. When I started up my computer it said that my operating wasn't found.I made a windows 10 USB boot loader and it says bootmgr is missing.
    I don't know what to do and I can't buy things I'm poor. This is my only laptop and I don't know what to do. The laptop I made the USB on it doesn't work that well like downloading things, something's work and some don't.

    Do you want to clean install Windows 7 with Windows 7 as the only OS? If that is what you want to do, then you will boot the computer from the Windows 7 USB flash drive. When you get to the choice to upgrade to Windows 7 or Custom Install, select the custom install option. That will give you a list of all partitions on all hard drives. On the hard drive that you want Windows 7 on, delete every existing partition on that hard drive until you have 1 unallocated space (that will erase that hard drive). Then just pick the unallocated space and next to install Windows 7 to the hard drive and let Windows 7 partition it the way that it wants.

    Yes, that's what I want to do.

    ive tried that, but it never boots Windows. It just skips to a black screen and says
    checkign media [fail]

    i set bios options to boot from USB as well, + tried uefi on and off
