I've tried boot-repair with the recomended settings but it is still not working.
boot-repair log follows up.
I couldn't solve the problem by myself. I was wondering if you can help me.
Windows 7 wont startup after ubuntu installation.

Thank you,
Alexandre

Is this a uefi /secureboot machine?

Did you install Ubuntu on a separate partition or disk? If you installed it onto the Windows partition then you have probably overwritten Windows 7. If you installed it on a separate partition or disk then for some reason grub is not seeing the Windows partition. You could try "Grub Customiser" as this searches for the extra OS's and as well as adding them to GRUB menu. Grub will find Windows 7, if it is located on a separate partition or disk. I have each OS on a separate disk and both Grub and Burg find them without a problem.

Before installing grub customizer update grub. Usually that does the trick enough.

You cannot install grub2's boot loader to a NTFS partition's PBR or partition boot sector. Windows has essential boot code in the PBR.


sda2: ____________________________
File system: ntfs
Boot sector type: Grub2 (v1.99-2.00)
Boot sector info: Grub2 (v1.99) is installed in the boot sector of sda2
and looks at sector 955648024 of the same hard drive
for core.img. core.img is at this location and looks
in partition 112 for . No errors found in the Boot
Parameter Block.



Use testdisk to restore from backup PBR.

Fix for most, a few have other issues, better than windows fix in many cases as it also fixes other parameters:
If win7 use small 'system reserved' NTFS partition instead of the partition where windows was installed for win7
This has instructions on using testdisk to repair the install of grub to the boot sector for windows from Ubuntu or Linux LiveCD.

Then to add Windows to grub menu run this after rebooting into your install.
sudo update-grub
