Lenovo Ideapad z580 Bios & boot issues (windows 10 64 bit)

2016-04-12, 19:34 PM

Lenovo Ideapad z580 Win10 64


I updated the bios with the private update (I know now that I should have used the public update)


Then it showed this menu:



Whenever I selected HDD, the screen would go black for a couple of seconds and return to this menu.


I fixed it by going into BIOS and changing bootmode from UEFI to Legacy. it booted but now everything is slow. It takes 5 mins to boot up and a further 15 minutes to reach usable speeds (I only have 4 startup programs). I tried changing it back to UEFI and it gives me the same problem as shown in the picture.


I tried installing the public update, but it says that I cannot update as the current bios version is the same or newer.


I went into BIOS and enabled BIOS back flash, and now when I try to start the public update, it just crashes.


I also cannot access the start menu (this problem may be seperate and unrelated)


I have backed up files and am prepared to do a clean reinstall of Win10, but I feel this won't work as it's a BIOS issue.


The computer is unusably slow: what should I do?
