December 15th, 2011, 02:10 AM
I was using windows 7 but needed to use Ubuntu for my university so i did dual install, everything automatic and installed Ubuntu 11.10 alongside 7.

In the Grub interface i see windows 7 but when i selecti it a black screen appears for a second and then back to Grub interface. Ubuntu works fine.

Please if anyone understands whats going on pls tell me.

I read in similar posts (i tried everything i saw so far) that i should give information from boot info script:

Welcome to the forums.

You installed the grub2 boot loader to the Windows boot partition and that is how you are booting. But installing grub to the NTFS partition boot sector (PBR) you have broken Windows. All NTFS partition have to have a NTFS signature in the PBR and if bootable info on what to boot (bootmgr for Vista/7 or ntldr for XP).


sda1: ____________________________________________

File system: ntfs
Boot sector type: Grub2 (v1.99)
Boot sector info: Grub2 (v1.99) is installed in the boot sector of sda1
and looks at sector 947506640 of the same hard drive
for core.img. core.img is at this location and looks
for on this drive. No errors found in the Boot
Parameter Block.
Operating System:
Boot files: /bootmgr /Boot/BCD



The above should look like sda2.

You need to first install the grub boot loader to the MBR of sda not the partition sda1. sda1 is in Windows the (hidden) boot/repair partition.

First from your working Ubuntu install grub2 to sda. Not sda1.

sudo grub-install /dev/sda
sudo update-grub

Reboot and confirm that Ubuntu still boots ok.

Then follow this set of instructions to use testdisk to restore the backup PBR for Windows. If backup is also damaged then you have to have to use the Windows repairCD, that it looks like you already have in your CD drive.

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.

I used the windows 7 recovery disk , used bootrec.exe /fixboot and says unrecognised file system maybe it is corrupted.
Note please that yesterday i used fdisk on ubuntu and showed that sda1 was not ntfs but something different (don 't remember exactly something like hidden ntfs) and used the utility to change it

Pls any suggestions ?

Frankly, I'd just start over, by reinstalling Windows 7, and then following these instructions, to dual boot:

http://ubuntuguide.org/wiki/Ubuntu:Oneiric#Dual-Booting_Windows_and_Ubuntu

or look here, for additional tips:

https://help.ubuntu.com/community/WindowsDualBoot

Edit:

If you don't, you might be able to fix it, but, you'll probably end up with an install held together by duct tape, and bailing wire.

I used the windows 7 recovery disk , used bootrec.exe /fixboot and says unrecognised file system maybe it is corrupted.

The Windows boot repair is notoriously unreliable, unfortunately.

Try booting from the recovery disk and running Startup Repair three times -- that's right, three times.

IF that doesn't work, you might then be able to repair it using Boot-Repair:

I think Windows fixBoot & chkdsk (both required) do not work until grub is removed, as it has to see it at least as NTFS.

Testdisk also has a create new boot sector [Rebuild BS] that is NTFS. That by itself does not fully fix it as it is not bootable, but a working NTFS partition. Then the Windows repairs should work. See screen shots in last post for testdisk screens.

Thanks everyone for your replies
I managed to solve the problem by changing the active partition to the partition windows is installed(sda 2) instead of sda1 and then running bootrec.exe then reinstalling Gru and then updading gru to include windows

The important step was to change active partition :
In recovery mode select command promt .
disk part
list volume
list partition
select partition
active (to make it active)
exit

then continue with the rest of the standard procedures

sda1 partition is ruined and is not used but its ok i can actually breathe now
