You can download the Windows ISO file from their official website using Ubuntu. But you will need an USB you won't be able to install it on your computer.

Install windows from hard disk

1- download windows 7/8/10/11 iso file.
2- extract the iso file to ntfs data partition.
3- sudo update-grub or add a menu entry to /boot/grub/grub.cfg.

menuentry "Windows installation Environment" --class windows --class os {
    insmod part_msdos
    insmod ntfs
    set root='hd0,msdos1'
    if [ x$feature_platform_search_hint = xy ]; then
      search --no-floppy --fs-uuid --set=root --hint-bios=hd0,msdos1 --hint-efi=hd0,msdos1 --hint-baremetal=ahci0,msdos1  55DD0595418E5BFC
    else
      search --no-floppy --fs-uuid --set=root 55DD0595418E5BFC
    fi
    parttool ${root} hidden-
    drivemap -s (hd0) ${root}
    chainloader +1
}

Replace 55DD0595418E5BFC by the uuid for that partition which given from disk utitity.
Replace 0 and 1 in the entry by yours, 0 is the hard no. and 1 is the partition no.

note: install windows will delete grub boot loader frome your hard disk so if you want to back to ubuntu you will have to use boot-repair or ubuntu live USB to restore grub boot loader and add Windows entrys to grub menu so no need to windows boot loader again.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
