Install os-prober

Then do


sudo os-prober


sudo update-grub

Does that solve it?

Did you notice the missing files in the windows partition. And this line in the script.

### BEGIN /etc/grub.d/30_os-prober ###

[carl4926]

Yikes!
Does the OP have a windows DVD? I wonder?

[wilee-nilee]

First having windows farther into the disc can cause problems, but you are also missing specific boot files, here is your partition with the files added which should be there highlighted.

sda5: __________________________________________________ _______________________

File system: ntfs
Boot sector type: Windows Vista/7
Boot sector info: According to the info in the boot sector, sda5 starts
at sector 2048.
Operating System: Windows 7
Boot files/dirs: /bootmgr /Boot/BCD /Windows/System32/winload.exe

Couple of ways to fix this so lets wait for some more help as there are some awesome users on line as we post.

It helps us in helping you if your are more concise. Such as I have a install dvd, or I have downloaded the recovery, iso, and even have it burned. You will need one or the other basically.

[vinise]

ive tried both my install dvd and the recovery... both are not abble to repair...
i'll reinstall windows... and we'll see after to reinstall grub

If you can and are backed up wipe Ubuntu and put W7 at the beginning of the disc then Ubuntu after. Also if you are just going to reinstall Windows in the same place make that partition first with gparted=NTFS, otherwise you may loose the Ubuntu.

Edit: with a closer look at the script you also have W7 inside the extended that doesn't work basically, it needs a primary partition outside of the extended.

[oldfred]

wilee-nilee is correct. Windows does not boot directly from a logical partition. You have to have an install of windows in a primary partition that will then boot the install in the logical.

It also looks like you copied your windows from sda1 which would normally start at sector 2048.

Boot sector info: According to the info in the boot sector, sda5 starts
at sector 2048.

[carl4926]

It should be possible to make some free space on sdb to backup important files to.
sda is pretty messed up and I'm struggling to see just how you managed to do what you have done.

[Quackers]

Also the boot flag is set on sda1, leading me to suspect that the 2 missing boot files were there at some time.

[jacob.david]

I had a similar issue and I solved it by the following method.
I had windows 7 on sda. I was trying to install Ubuntu on sdb. While installing Ubuntu I chose sdb as "Root partition". Later in the BIOS I choose sdb over sda in the booting sequence. Everything was OK and now I have both working fine.
