I was installing three different systems on a hard drive: Windows Server 2012 R2, Ubuntu Client 16.04 and Ubuntu Server 16.04. When I finished installing Ubuntu Server I can't access Windows Server via the new GRUB, only the Ubuntu systems. Why is that? This is a log of things I was doing:
- Formatted a 250GB HDD (into NTFS?)
- Created a 150GB Partition for Windows Server
- Installed Windows Server on that partition
- Tested Windows Server, it works fine
- Installed Ubuntu Client, works fine, I can choose between Windows and Linux in GRUB
- Installed Ubuntu Server, installed new GRUB during installation
- Windows doesn't show up in GRUB, only Linux Client and Linux Server
- Plugged in the Windows install drive, entered into repair mode, typed
- Windows boots up, but no GRUB
- Went into the Ubuntu Server installer, advanced options and typed in
- Windows doesn't show up in GRUB, only Linux Client and Linux Server.
How to make all the systems appear? All the partitions are fine. I think I have windows on sda1, ubuntu client on (sda3?), exchange space on sda5 and server on sda4.
