I use windows 10 and ubuntu 14.04.4 in dual boot.Recently whenever I try booting into ubuntu,it shows me this,
ata1.00 SRST failed (errno-16)
ata1.00 SRST failed (errno-16)
ata1.00 SRST failed (errno-16)
ata1.00 SRST failed (errno-16)
....giving up
then busybox console shows up.I tried fixing this following this, Boot drops to a (initramfs) prompts/busybox
if fixed my problem for once but after I did my stuffs, shut the pc down and then came back again, the problem reappeared. This time, I cant detect my entire hard drive using live CD(ubuntu iso in a usb stick). But grub is still fine and I can boot into Windows 10.The only thing thats different now is that during BIOS messages,it takes about 20-30 seconds just to detect my harddrive which was faster before.Could that be the issue?
by the way,I use Diskinternals Linux Reader for copying files from my ext4 partition when I am on windows and I can still see that partition and can see my files as well.
