I have a Seagate 1TB USB Hardrive that seems to power off when the grub screen comes on the laptop. I therefore cannot boot to the Ubuntu OSs on it. The boot repair script is on paste.ubuntu.com/5791247/. The USB HDD seems to power on with the computer, and after I choose a partition on sda[internal]. It used to do this to me before, but only on restarts, not power off then turn on. I have an Acer 5537 laptop, but the Bios is quite basic[simple]. Thank you for your help. Colin More info took wireless mouse off , got these errors; 1] no such device, 2] Hd1 cannot find C/H/S values, 3] load kernals first.
