I have windows on one SSD and Manjaor on another, plus some additional SSDs for storage.
Initially everything was fine, I had installed Ubuntu and I was able to dual boot just fine. Then i decided I didnt want that and went for Manjaro. And still everything was fine. At some point , trying to debug graphics card issues, I did a clean install of Manjaro and forgot to set the bootloader location and it just chose one of my SSDs.
Then no more grub. I tried a lot of steps but it just was not recognizing windows being anywhere and kept assigning some random drive as having windows .
So i clean installed both windows and Manjaro and no grub anymore, i just tried this refind bootloader and nothing, system just boots into linux. Yes windows is there and it works fine. I have done the grub-update among other commands that do not return anything or have no effect. I have played with boot order in my bios to see if maybe it was on another drive and the only thing that happens is I either boot into linux or windows or nothing…but never a grub menu.
