Boot device not found.

Hello.

I migrated a windows HDD to an SSD and when I booted I got.

no os can be found

I went home to my personal PC and took out my SSD which had arch on and stuck in the windows SSD.
It booted fine and I then unplugged it, Stuck my Arch SSD back in and now I am getting the same error as I had on the windows PC.

Boot Device not found

I read somewhere online that the same happened to another user and windows messed with his boot partition or something like that. I lost the link.

Re: Boot device not found.

You probably just need to re-create the NVRAM boot entry. Either re-install the bootloader to the disk or use efibootmgr(8) for that.

Placing the bootloader .efi file at /EFI/Boot/bootx64.efi on the EFI system partition will ensure it is loaded if no boot entries exist.

I figured it was something like that. I re did the entire boot partition on my arch SSD and everything is okay now.

I am just reinstalling windows on the clients PC.

Thanks for your help.

that's quite a waste as it's not required:
boot winPE and use bcdboot to re-install the windows bootloader - it's equivalent to grub-install or bootctl install
