What is the most efficient way to install Windows 7 from Ubuntu 14.04?

Question

linux

Ubuntu 14.04 is installed on the machine, how can I install Windows 7 as a second system? With what help to create a bootable USB flash drive, and what about Grub later? How to install Windows 7 after if Ubuntu 14.04 is installed on the machine?

before that I only installed ubuntu after windows was installed on the machine

What if it's the other way around? For example , here it is written how to install ubuntu next to windows - that is, it means that vindovs is already installed, and ubuntu will be installed after the "second" system. I'm also interested in the "backward story" - I have ubuntu 14.04 installed on my machine, - how can I deliver windows 7?
Question related to the bootloader:

what else is there besides grub? and can the Windows bootloader boot linux?

Answer 1

If there is already empty disk space or another disk for the Windows partition, then the method is simple.
There is a discussion here .
The bottom line is this: save the boot sector, install Windows, which will overwrite this boot sector, then copy the saved MBR to the system disk and write it to the bootloader.
If you read a lot of letters in scrap:

Install Ubuntu
Save MBR
dd if=/dev/sda of=ubuntu.lnx bs=512 count=1
Install WinXP
Move ubuntu.lnx to drive C: and add the following to boot.ini:

Answer 2

Somehow I needed Windows a few months ago, but I was too lazy to make an installation flash drive, but VirtualBox was on the machine ...
We create a virtual machine and connect a disk to it on which you want to install Windows.
We install Windows into it as we usually do it in a virtual machine.
We stop the machine, do update-grub in the console.
We are overloaded.
Profit.

Answer 3

Install how? In a virtual machine or install a second OS?

Answer 4

1. Read what grub is and how to restore it.
2. Gparted frees up space for Windows.
3. You install Windows on free space, making a partition there, and all that.
Depending on the desires and Windows, you can get the following situations:
1) Windows does not see ubuntu, Windows is not interested.
2) Windows sees ubuntu, and the loader offers to load the hornbeam. Happiness, smiles, everyone is happy.
In case Windows does not care, you can restore the hornbeam liveseedy ubunta, or in any other way that Google prompts.
