Hi!
My multiboot with openSUSE 11.4,... and Windows7:
menu.lst of Suse:

Code:

title windows
    rootnoverify (hd0,1)
    chainloader +1

That means: no "makeactive" and no blank line after "makeactive"
To edit the menu.lst: If you have KDE:
ALT + F2 >

Code:

kdesu kwrite /boot/grub/menu.lst

or kate instaed of kwrite.
Gnome:

Code:

gksudo gedit /boot/grub/menu.lst

please help.. thanks in advance

John VV · 07-23-2011, 03:06 PM

did you take int account the VERY well documented issues with the win7 "recovery" partition that the oems put on the front of the drive ( too cheep for a real install dvd)
sda1 is that "recovery" partition

you do have a install dvd you got from MS ? right? they will snail mail it to you
if so fix the windows bootloader

If you don't have the win7 DVD, then you can get a recovery disk here:

I am puzzled by the output from your fdisk. When you set up Grub in your Opensuse install, your assumption was that Windows7 was on /dev/sda1, which Grub knows as (hd0,0). Alfredo10 suggested that it was on (hd0,1), which is /dev/sda2. But on your system, /dev/sda2 is an extended partition which comprises /dev/sda5, /dev/sda6 and /dev/sda7, but not /dev/sda3 and /dev/sda4, which are Linux, presumably /home, and Linux swap; physically, these are where Alfredo10 expects Windows7 to be. On the other hand, /dev/sda5 and /dev/sda6 are NTFS (Windows7) partitions.

So, two possibilities: you mistook the partitions when you set up OpenSuse and overwrote your Windows7 partition, or Windows7 is actually on /dev/sda5 (more likely than /dev/sda6), which is in Grub speak, (hd0,4). You could try that in the bootloader. In OpenSuse, the best way of modifying the bootloader is by use of Yast. Click on the green disc at bottom left, hover the mouse over the computer symbol, then click Yast. You then give the root password and the Yast window appears. in the fifth line you will see Bootloader. Click on this and edit the windows line to:

windows Other /dev/sda5

then save the configuration. Note that it really is /dev/sda5, not (hd0,4). And the best of luck.

Hi!
1.
That's a misunderstanding: As I wrote: "My multiboot" -> my menu.lst, not the list of the OP!
2.
I would try to find out where Grub is installed:
Commands in a Terminal of a Linux as root:

Code:

fdisk -l 2>/dev/null | egrep "Disk /|/dev/" | sed "s#^/dev/#Part /dev/#" | awk '{print $2}' | sed 's/://' | xargs -n1 -IX sudo sh -c "hexdump -v -s 0x80 -n  2 -e '2/1 \"%x\" \"\\n\"' X | xargs -n1 -IY sh -c \"case  \"Y\" in '48b4') echo X: GRUB 2 v1.96 ;; 'aa75' | '5272') echo X: GRUB Legacy ;; '7c3c') echo X: GRUB 2 v1.97 or higher ;; *) echo X: No GRUB Y ;; esac\""

Reply to Alfredo:
1. Yes, I realized that: the question was, where Windows7 installs itself; if in the second partition, as yours, then it has been overwritten, if in the third (or fourth) then there is a chance.
2. Since there is only one Linux boot partition, Grub must have been installed from there, and Yast is the easiest way to examine it.

alfredo10 · 07-25-2011, 02:47 PM

Hi!
With the command in answer #7, which I found here:
http://wiki.ubuntuusers.de/GRUB_Umge...0Zgrub%20Zfind
we would have one important answer.
And there are more useful commands!
