Brand new user installation was difficult questions

Hello All,
I finally installed Zorin here after finding a video on you tube. I could not install this because I did NOT understand the partioning. So anyway I only partioned the four main needs, the efi, the swap the root and I guess the home. I didn't know how to know what MB equaled to whatever else I needed. My laptop has two drives. The main one and a DVD (converted to house another drive). I wanted to keep windows on one drive. But while trying to install ZOrin the first time I must have done something to screw up my main windows installation and my laptop now after the Zorin install (SDB), will only boot up to zorin and doesn't see my other drive (SDA). Can I get some help here please? Thanks!
My laptop is an older MSI GP72-6QF 1795. Hasswell, Nvidia 960 I think GPU).

Can you boot into Windows when you set Windows at first boot position of your BIOS?

Thanks for the reply. So I THINK i tried that after dedicating about two hours to figure out what was going on. I think that would be a no. LSBLK command shows its still there the same as before though.

Welcome to the Forum @Artisto!
I've installed Zorin more times than I can count but have never had to partition anything in the process.

The efi part is concerning...
Anyway someone here has the answer don't worry.

Also this but please wait for someone with more experience than myself says ok?

To update the GRUB bootloader configuration on most Linux distributions, execute the following command in a terminal:

Code

sudo update-grub

This command scans for installed operating systems and kernels, then generates or updates the /boot/grub/grub.cfg file, which defines the GRUB boot menu entries. This is particularly useful after installing a new kernel, adding or removing an operating system in a dual-boot setup

Do you not have a Function key that allows you to choose which drive to boot to?:

" 5. Configure Boot Options :

2

SDA is still there and untouched, because you can open SDA in Zori.

You can also set SDA as the first drive to boot from, into Windows, but not into Zorin, namely through the BIOS settings.

What you cannot do, at the moment, is to boot from the second drive into Windows.

Confirm?

Can you please show us the output of your lsblk command? It will help us understand your devices and their partitions.

Thanks for the reply very much! So on my msi Gp72 6QF, my bios is F11 to get the usual menu. But Only the drive where Zorin is on shows. Again my other drive is there when I submit an LSBLK command. If I go into my bios, changing the boot priority doesn't do anything different!oscar@oscar-GP72-6QF:~$ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS sda 8:0 0 465.8G 0 disk ├─sda1 8:1 0 350M 0 part └─sda2 8:2 0 465.4G 0 part sdb 8:16 0 232.9G 0 disk ├─sdb1 8:17 0 976M 0 part /boot/efi ├─sdb2 8:18 0 7.6G 0 part [SWAP] └─sdb3 8:19 0 46.6G 0 part / oscar@oscar-GP72-6QF:~$

Yes that is correct. While windows is no big loss and I'm happier to have Zorin as my priority, I still don't like the loss of control here.


Here is a screenshot showing my windows drive. It says unmounted.

The screenshot suggests the Windows drive doesn't have an EFI partition (which would be FAT32, not NTFS). The output of the lsblk is very difficult to read due to the formatting, but i think it says the same thing.

I'm not an expert here, but the way i'm interpreting this is that Zorin (and Grub - the bootloader menu Zorin uses) doesn't have an entry for Windows because Windows doesn't have a bootloader (no EFI partition on the drive). Not sure what happened during the installation, but you might have to use a Windows rescue disk or something to recover the Windows bootloader. If there's nothing important on your Windows system, you could also re-install Windows on that drive. Once Windows can boot independently of Zorin, you can ask Zorin to find Windows' bootloader and update Grub so that you can select whichever without having to use F11 or whatever to choose.
