I have an older dell inspiron laptop. I had previously installed ubuntu on it with a completly encrypted hard drive. I decided that I want to reinstall linux with lighter apps, but my CD drive no longer works, and my laptop does not support booting from USB. I have another laptop which uses the same size hard drive (it's a newer latitude), so I thought I might be able to put the old hard drive in the new computer, reinstall an OS, then put it back in the old computer. I have tried this with puppy linux, but when I put the hard drive back in the old computer, I get a kernel panic. Does anyone know of a way I could install linux (any light version would work) in this manner? Is it possible for this to work at all? Thanks.
