My dual-boot laptop has two SSDs:

  1. A 480Gb disk containing the master boot record and Windows. (This disk has lots of free space because I no longer user Windows.)
  2. A 180Gb disk containing my Linux install. This disk is pretty much full as I use Linux daily. In fact I cannot install the latest LTS because I don't have enough free space.

I would like to relocate the Windows disk image to the smaller 180Gb disk (currently occupied by the Linux install) and vice versa. Basically, I want to move the OS in the large disk to the small disk and the OS in the small disk to the small disk.

How can I safely perform this operation? I know I will require an external drive, which I am ready to purchase.

  • Something doesn't make sense here. First you say "This disk has lots of free space because I no longer user Windows" and a couple of paragraphs later "I would like to move the Windows disk image"?? Anyway, reinstalling is faster and with expected better results. "Rotating" isn't a thing. Imaging and recovering to another drive and moving/expanding partitions will take a ridiculous long time and with a high risk of data loss. Jun 2 at 17:21

  • It really doesn't and doesn't change anything I already commented about. Jun 2 at 17:41

Moving isn't really the best way to go about doing this. Instead, you should:

  1. Back up all files on both disks
  2. Format the 480 Gb disk and install the OS you want
  3. Restore the linux files onto the 480 Gb disk.
  4. If you want, reinstall Windows onto the other one and restore the files from a backup.

    Yep, that's what I said :) Jun 2 at 22:38
  • Thanks Michael. Its just that I have lots of applications on Linux and I don't want to have to manually reinstall them all -- if I can remember them all, before I actually need them. In any case, I will do a backup to begin anything.
