I have an SSD with NixOS installed on it and an HDD that is currently a LUKS encrypted data store. I want to put Windows 10 on part of the HDD.



Since I've already installed NixOS, does this work.



Usually, when I've done dual boots I remember installing Windows first.



I plan on referencing this.

Thanks.

    In the past with BIOS/MBR systems what would happen is Windows would override the Linux bootloader, which would have to be restored after the fact to boot Linux. With UEFI systems the same could happen, but tools like efibootmgr can be used change the default bootmanager back to systemd-boot. I had trouble setting the default on my system (Dell Latitude) so I installed rEFInd.

You could install Windows and allow it to overwrite your boot partition.
Then you could use a NixOS live-cd to reinstall your NixOS bootloader.
Therefore first mount your system as you have done for installation to /mnt. Then run nixos-install again. Running nixos-install is idempotent so your nixos install is not in danger - your system will be re-installed based on your configuration.nix. After that you should be able to append the windows bootloader as described in the wiki

            How many registers does an x86_64 CPU actually have?

            Image
            Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
