Hi
I have a desktop machine that dual booted w7 and opensuse 13.2. I have little experience in linux (or windows) and when I tried to upgrade to Leap, naively formatted the mbr partition to install the grub :shame:. Opensuse Leap starts well and i’ve used it for several months now.
But, I need to use w7 to run some adobe programs (photoshop etc). Is it possible to “repair” the mbr?
This is my windows partition: https://drive.google.com/open?id=0BzBoLoUQva9aNWdVa1QxU3Vhemc and this my mbr, where i installed the grub: https://drive.google.com/open?id=0BzBoLoUQva9aRUFDLTRtZ2loRFk
Can you help me fix my mess?
My machine has an AMD processor with two cores (hope this helps…)
I still do not understand the problem. You said you had dual boot system that worked. What does not work now? Please describe what you expect and what you get.

Thanks for your reply. Before time when I started the machine I could choose between w7 and opensuse 13.2. Now the machine starts “directly” to opensuse Leap. It doesn’t show the menu where you can select the operating system.
Thanks for your support and hope this information helps lol!
I suspect that the main issue here is that you have a UEFI system. But you may have installed 13.2 for legacy MBR booting. That’s a mistake. Mixing legacy booting and UEFI booting can cause the problems that you are seeing (such as not able to boot Windows from the grub menu).
Try hitting F12 during boot (or F9 if this is an HP computer). Does the BIOS provide a boot menu, and can you select Windows from that menu?
Unless you have another drive you are not showing I don’t see a Windows partition. What you seem to have is a EFI booting Linux only system.
So you installed EFI not MBR boot which is OK but seems to have over written Windows
Show sudo gdisk /dev/sda
It will better report partition type on a GPT partitioned drive
Always pay careful attention to the partition scheme before accepting and committing to it when installing Remember the installer can not read you mind and uses the best guess at what you intend. You can always override it’s choices. Installing an OS is a lot more serious then installing an app.
I see I committed a mistake in the fdisk -l command. I repeated it:
$ sudo fdisk -l

Thank you very much for your answers and support lol!
Guessing that sda1 is supposed to be the efi boot partition yes you messed up it has to be a FAT formatted partition not a Linux format
So looks like you installed openSUSE in MBR mode since it would not boot like this if installed in EFI mode. You can not chain between OS’s if they boot in different modes
Don’t know how to fix this but to start EFI boot partition has to be FAT. You must first reformat it then you could in Yast -bootloader change to EFI boot for openSUSE but yo u still have to repair Windows and I have not a clue how you will need some sort of Windows rescue
I see the grub menu and the next screen is of opensuse options. Nothing about windows.
P.S. and you ignored my question about grub.cfg.
Oh, excuse me. Here is my grub.cfg

If you run as root “os-prober” - does it find Windows? Your “fdisk” output shows 100M partition 1 with type “Linux”; your grub.cfg output shows that GRUB files are on partition 6. So partition 1 is not /boot. What is on this partition? Please show output of “df -h” in Linux.
It is confusing since you first showed a EFI boot disk then an MBR boot disk with a small Linux partition that looks as it should be formatted FAT for tan EFI boot. If one OS is installed MBR and the other EFI they won’t see one another and without a proper EFI boot partition the EFI OS will not boot at all. Not at all sure how to fix the problem. W7 is probably still there just unbootable . You can recover any data
What is lost is most likely Windows System partition that contains Windows bootloader. This partition is not mandatory (if you update from earlier versions this partition is not created). So you should be able to recover Windows bootloader either on System partition or on Windows Boot partition (which contains Windows folder). But that is really topic for Windows forum.
I tried to correct it through windows but, my linux partition was erased (and had to reinstall everything…). I good hope that I can fix it from linux. Is it possible? Can you tell me how, or where to look for a solution?
Thanks rotfl!
OK you still must use the same boot method. both must be MBR or both must be EFI in order for one OS to see the other. Multiple drive is not a real issue either EFI or MBR will work but you can not mix.
In future show ALL output from commands you showed only one drive. fdisk -l will show all drives. Don’t edit the output
