Installing Windows 7 as a second system alongside Ubuntu 12.04.1 LTS?

Question

linux

Situation: the laptop is running Ubuntu 12.04.1 LTS, working and fully customized. It is necessary to install Windows 7 as the second system. As far as I understand, the main problem is that the bootloader can be overwritten and ubuntu will come to an end.
How to solve this problem without using a virtual machine, and saving the already working ubuntu?

Answer 1

After installing the seven, roll grub?

Answer 2

Restoring grub is a 5 minute job: http://goo.gl/3Z1z

Answer 3

Just today at work I did what you need according to this manual. (Ubuntu was there, then I installed windows7) / True, 2 partitions for Windows were previously allocated on the hard disk (although I allocated ubunta during installation).
I did not want to do update-grub (that is, the bootloader did not see the seven). After the reboot, I made this update-grub from under the live system.

Answer 4

Most importantly, do not touch the sections that you did for ubuntu. Windows will only overwrite the MBR-record at the beginning of the disk. After installing Windows, you will need to boot from the same installation disk. An example instruction is here . Remember that if you do not touch the ubunta partitions, then you will not lose anything, and reinstalling GRUB as written above is a five-minute job
