I had multiple disks in my PC, one with Windows and one with Linux. The drive with Linux had the boot record I guess; I removed and replaced that one with a new disk and again installed Linux on it (so the Windows disk has been the same the while time), but I can no longer log into Windows while this new disk is installed and the old disk is removed. I can log into Linux while the new disk is installed, and if I swap back to the old disk I can log into Windows.

How do I fix things so I can not into Windows or new Linux while the new disk is installed? I don’t mind reinstalling my Linux OS, but I really don’t want to reinstall Windows.

    Thanks for the response.

    you can try copying the Windows boot sector byte for byte from the swapped out disk to a partition on the new disk

    How would I go about doing this? Macrium Reflect?

      On Linux my go to tool for resizing and creating partitions is GParted, with some help from command line tools like dd to copy the data over.

      Gnome’s disk utility GUI has the option to create a disk image from a partition that you can later restore.

      If you want to do a direct copy, without a temporary copy somewhere, I only know the terminal command line:

      dd if=/dev/disk/by-id/ata-Samsung_SSD_850_EVO_250GB_S21PNXAG803885Y-part1 of=/dev/disk/by-id/wwn-0x5002538d403dda0c-part3 statusprogress bs=8m

      This would make a direct, byte for byte copy from the first partition of my Samsung SSD to the third partition of my Crucial SSD. Other ways of addressing the disk also exist (i.e. /dev/sda3 to /dev/sdb1, or in the other ways you can refer to a disk or partition somewhere in /dev/disk).

      I’m sure there are Windows based tools that can do the same, I don’t have experience with many of them. Last time I had to mess with this type of disk partitioning for Windows installs I think I used a tool called EaseUS?
