Windows 10 Not Recognizing Drive

[DapperDeer]

Hi there,

I'm trying to get GRUB2 to allow me to boot into both Ubuntu and Windows 10. I've gotten it working for Ubuntu and now I'm trying to install Windows. When I get to the Windows installation screen where I need to pick a drive/partition, no drive shows up. Opening the command line and doing `diskpart list` returns no drives, so I'm unsure how to proceed. I originally thought it was just because my drive was SCSI but I have two Windows 10 installations that use SCSI drives, so that must not be it. I've allocated 80GB to the drive where a 20GB partition is for Ubuntu, 512MB Partition is for GRUB2, and I was going to give Windows the rest.

Is this a limitation of the VM? If not, what am I missing?

Thanks.

So you’re trying to dual-boot Ubuntu and Windows in a single VM? If so, why not just build 2 separate VMs?

Yes, I am trying to dual-boot Ubuntu and Windows in one VM. Mostly just curiosity, see if I can get it to work and to gain some experience working with GRUB. It's the dual-boot itself that I'm interested in, not necessarily anything after the fact.

Hi,

Not a limitation of the VM, but a limitation of Windows.

Windows does not know grub2 and as such does not give you easy a way to dual boot with linux.

The normal order to setup a dual boot system is to first install Windows, then add Linux after that as Linux will configure grub for you.

Got it! I'll do it that way, thanks so much!
