Hello there, greeting, my name is Wandry, I’m new user to opensuse leap 42.2, before this I use elementary os and then manjaro but the stability of opensuse leap really attract me. I have disk with windows 7&10 installed along with manjaro and then I format manjaro drive and install opensuse on it, everything work fine except i can not find a way to boot to windows 7 (it will go directly to 10, elementary n manjaro will show windows selection menu if i choose to boot windows in grub). Please I need your help. And one odd thing is i can’t shutdown windows 10 normally anymore (have to use forced shutdown from run or it will go back to login screen) after opensuse installed. Thank you before
Os-prober bring no result
Is this machine a UEFI or BIOS?? IF the machine is a UEFI then all OS must be installed to boot using the same method one can not be EFI and another MBR they will not see one another
All is BIOS (legacy)
Opensuse leap can boot windows 10 just fine but it dont show windows oses selection menu
You did not answer question. Installing on a UEFI machine can lead to mixed boot methods and a OS that is installed one way can not see an OS installed to boot the other way. Before any can help you must say if the machine is UEFI based or BIOS based. If less then 5 years old it is probably UEFI based
The machine is using bios, and i installed all of them on legacy mode not uefi mode
Sorry for the late reply, actually I’ve replied twice using my phone but the message disappeared, strange. Ok so all of them are installed using legacy mode (not uefi), my laptop use BIOS although there are EFI option on the BIOS but I disabled it and use legacy all the time, when I’m in windows I can use easyBCD to choose the default OS (Windows 7 or 10) and everytime I’m in Leap boot menu and choose to boot windows it will only boot the default Windows although I’ve set the Windows OSes selection menu on but it won’t show at all and directly going to default Windows OS, never have this problem with Linux Mint, Manjaro or Elementary OS.
Show us fdisk -l
I suspect you booted the installer in EFI mode which defaults to a EFI boot and a EFI booting OS will not see a OS booting MBR
Sorry again for the late reply. This is my fdisk -l result:

And one more, I can not connect to wifi, no wifi network at all, how to install wifi driver, I use lenovo z410, in mint, elementary and manjaro it automatically use broadcom driver
No swap no home partitions? You use DOS partitioning but have no extended to hold additional partitions?? 3 Windows partitions. Does look like MBR boot.
If Understand You can boot to openSUSE and can from grub boot to Windows 10 but NOT to Windows 7. Or are you using someother method to boot to Win10??
And you run os-prober as root and get nothing???
I’m missing something here 
OpensSUSE is opens source only thus you often have to load proprietary drivers from another source ie packman. Also for WiFi you need to use NetworkManager not wicked. lspci should tell you your WiFI hardware
I am sorry but I don’t really understand, I always installed linux without SWAP and the performance is always good and never have any problem with triple booting to Windows 10 and 7, I can change the default windows os in Windows 7 or 10 so when I choose to boot Windows from grub it will boot to the default Windows (whether 10 or 7) but it never show the Windows selection menu (usually after I choose to boot Windows from grub it will show menu to choose between 10 and 7). I’m still beginner in Linux, I don’t really understand many thing and just a user so I’m sorry if I don’t really understand your explanation.
Be sure that fast boot is off in Windows it leaves the partitions unusable to Linux. But then I don’t think Windows 7 has fast boot. but if you mount the 7 drive from 10 and fast boot is on it may leave the drive not shut down completely. I don’t think others are seeing this so it has to be something odd about your setup :\
