[OpenIndiana-discuss] OI new user questions

[Stephan Althaus]

Hello!

Yeah Win 10 installation is always harmful with other OSes 
pre-installed. You have to remove (or disable in BIOS) all other disks 
to have a Win 10 install that doesn't mess up things.

I currently boot Openindiana from MBR on 1 SATA disk, and debian on zfs 
root via UEFI (BIOS boot selection via F12), no problems here.

My Laptop has GM107GLM [Quadro M1200 Mobile] using NVidia Solaris driver 
455.38.

I am using Virtualbox 6.1.16 distributed with OI no problems here (there 
had been 1, 2 in the last years all solved).

I'm a proud user of Openindiana, very nice OS, i'm still learnig...

Greetings,
Stephan

I had a Win10 and Solaris 11.2 dual booting install, on the same disk using BIOS, i.e. MBR disk. Then an W10 update silently changed the disk to UEFI (GPT disk), and Solaris 11.2 was still on MBR. So I could boot W10, but not boot Solaris. It took me a long time to figure out why Solaris would not boot. I had to reinstall Solaris using UEFI.

> To solve my problem of BIOS os and UEFI os, I wonder if this might work: I remove all disks except one, and install Win10 using UEFI. Then I remove all disks, and insert another disk to which I install BIOS OpenIndiana. Then I insert all disks, and when I boot my PC, I choose which OS to boot from the disk boot menu by pressing F11. Do you think this could be a way to have both BIOS OpenIndiana and UEFI Win10 on my PC, but on different disks? I have read that you should not install BIOS and UEFI oses on the same PC, even on the different disks - but I dont know why. I cannot find information on this. But if I choose the different disks to boot in the boot menu, this could work? Anyone know?

If you boot Win10 install usb and only look at the different disks in your PC, i.e. check the sizes of the disks, and then exit without doing anything - this will mess up your ZFS disks. W10 install software will mess up disks that are not NTFS. ZFS is something new, so Win10 install software will overwrite the ZFS disks even scanning the ZFS disks. If you do get your ZFS disks messed up this way, I have heard that you can try to import the zpool and scrub it, and it might solve this mess. Another way to solve this problem, is to remove all non ntfs disks from your system before installing Win10).

On a UEFI installed Solaris 11.3, it is not possible to install the latest Nvidia 1070 Ti driver because the driver explicitly requires a BIOS Solaris installation. To install GTX 1070 Ti, you must install Solaris 11.3 as BIOS, and not UEFI. If you have UEFI, there are no GTX 1070 Ti driver at all. You need to use VESA driver.

Because Nvidia GTX 1070 Ti driver only installs on BIOS Solaris. To solve this problem, can I still install OI as BIOS, and Win10 as UEFI as outlined in point 1) above? And this would give me Nvidia driver for GTX 1070 Ti?
