Dual-boot windows 10 and Leap 42.1 - Lenovo Ideapad 700

English Install/Boot/Login

Hello,

I am very new Linux user. So i dont have much experience in working with BIOS,GRUB etc…
I installed Win10 very easily on my machine. MY laptop has 1 TB HDD.
Processor 6700-HQ Intel Skylake, Nvidia Geforce GTX950M, 8GB RAM DDR4.

Now, i want to install opensuse Leap on my 300GB separate partition from a Live USB stick.
Installer creates 4 partitions. BIOS GRUB-about 15 mb , linux swap, linux root and linux home.
I set the root partition to be Ext4 .

PROBLEM 1:
Install process goes fine but then i have a problem with booting (fast boot disable, secure boot disable, legacy first bios - did all that).
My laptop goes directly to windows 10, only way i get openSUSE to boot is with Live USB stick inside and then from the menu I choose Boot from hard disk.
Then GRUB opens then but I cannot see windows, only openSUSE.

PROBLEM 2:
I installed the software but then i had a problem with screen freezing in range from 1-5 minutes since my loggin then i would have to do a hard boot, couldnt move mouse or anything.
Before booting to destkop i would get an error, but was able to boot with nouveau driver - so i set to kernel boot parametar nouveau.modeset=0 and that fixed showing up that sum of errors.

Everything was ok now, i was able to boot (still only with Live USB stick, then not seeing win¸0 in grub), but freezing stopped. I also then fully updated the system.

PROBLEM 3:
After a few days of normal working suddenly again screen froze, i had to hard boot, and now it freezes 5-15 seconds inside of fully loaded openSUSE again and again.
I get an error while booting something like **acpi platform device creation failed no cache mode page found

** I mean its really an agony i would only like to normally enter my opensuse or windows from grub and then work without freezes.

I only need opensuse for working with** openFOAM**, I dont really care about graphic driver that much if its to hard to set it up and running because od that Optimus technology,
it would be enough to get the intergrated graphics and system working.

If somebody could help I would really really appreciate it!! I’ve been trying to get it work for a week or more.

Ok how is Windows installed MBR or EFI boot? both OS need to use the same method in order to chain from the boot.

Some Machines insist on booting Windows there is a kludge to work around this but it is somewhat complicated

But on a modern machine you have a UEFI not a BIOS but you can set things to act like a BIOS with legacy mode

There should be a UEFI boot menu but the hot key to get to it is hardware specific sometimes F10 F12 maybe something else should show on the machines slash screen

Since you mention 4 partitions I guess you installed openSUSE in EFI mode. The fourth partition is the EFI boot partition (small FAT) mounted as /boot/efi

Since it seems to have been created I’d say Windows may be installed in legacy (MBR) mode. There is normally only one of them. SO not sure at this time what you have

Problem with video - are you fully up to date? Also may want to use the proprietary NVIDIA driver But best to start a separate thread here ie one problem per thread
