then, if you ever get to that point, let me know and I can explain the rest. I am able to take out the hitachi disk on an another computer and it works fine.Tried to format it but when i put it back in my acer laptop neither bios or windows installer recognise it, help plz.So now I'm thinking the problem is with the hard drive. I have had the same problem but instead with kali linux, I have two separate drives one running kali and one running windows 10.After rebooting into windows 10 from kali linux, my kali linux drive is gone even the bios can't detect. There has to be something wrong with the way the OEM set up the system if it's not the BIOS.A few days ago there was an unfortunate occurrence that caused a problem which I have run out of ideas to attempt to solve. I was using Windows and it wanted to update but I was in the middle of something so I told it to wait. My system was dual booting Windows 10 Technical Preview and Arch Linux.Upon restarting the system into Windows, it performed the Second half of the update.I worried it might have broken something, but there were no problems until the next time I booted.
Its first partition is a recovery partition, and C: is the 2nd partition.A few minutes later the system froze, as experimental systems sometimes do.I powered off by means of holding the power button.I took the drive out and everything else will suddenly boot if I change the boot options now, but that doesn't fix the fact that the laptop kinda needs the primary hard drive to work as before.So I found I was able to boot it on my desktop, but it gave me a winload digital signature error.
