I have a Lenovo Ideapad 100. Previously I used to have a dual boot on a single built-in HDD and everything was perfect. For christmas I got a SSD and I wanted to set up a new dual boot: Windows 10 on the HDD and Ubuntu on the SSD. Firstly I uninstalled Ubuntu from the HDD, I then installed Ubuntu on the SSD with a pendrive, but there is no way I can make Ubuntu boot. When I turn on my PC, some error-messages show up, but they immediately disappear so that I can't read them. Then I end up in the grub command-line interface. There I can do two different things:

  • I can type 'exit' and then hit enter, now I can choose between different boot options so that I can load Windows 10 like nothing has happened.
  • Otherwise I can type 'ls' and some tuples show up, like: ... and finally "error: failure reading sector 0x0 from 'hd1'" (there are other two similar errors"

Can someone help me? I found different questions here about dual boot, but everytime people had trouble loading windows, or the mistake was the different OS installation (UEFI coexisting with BIOS). The latter doesn't seem to be my case because when I used to have dual boot on the same HDD, everything worked perfectly.

Not sure how far you are with configuring either operating system. But its best to install windows THEN Ubuntu. This allows grub to configure the boot loader accordingly for both OS.

My process usually is:

1) Install Windows

2) Enter disk management to shrink partition volume (For you this step is not necessary)

3) Enter Linux USB and install

4) Select your partition(drive for you) and install

Ideally this will allow GRUB to see the windows install and configure the Boot loader accordingly.
