Hello to everyone,

I have installed Win7 on my internal HD, and Kali Linux on second partition on my external HD. I placed Grub loader on my internal HD where Win7 is.

When computer boots, Grub loader goes directly in rescue mode with following errors: No such device, and file system error (or something like that). But when I manually enter into BIOS boot and pick to boot from internal HD everything works fine and Grub loader is raised with dual boot options.
In rescue mode with LS command I concluded that it can`t see the external drive, and I suppose that No such device error refer to this. But I`m confused - if it can`t see the external HD when computer automatically boots, how it can see it when I manually boot from Bios from my internal HD?

Can anyone help, it is really annoying to go into BIOS every time I boot or power on the computer?

Thank you
