Before you go too far, take another look at the BIOS setting. A common tip,
back in the day, was to disable the camera from the BIOS. It should be
somewhere under the "Integrated Devices" menu...

Since you say that the machine was pre-owned... You never can tell what
the prior owner may have done. If s/he's available to be asked, great,
but here are some ideas that might save you time and money and
convenience of getting an external camera:

It may be that the prior owner at some point opened up the device, and
that in the course of that the connector to the camera became loose, or
the owner just neglected to re-connect it. Most laptops are pretty easy
for a non-technical person to perform the minor partial dis-assembly
necessary to access and service that connector. Sites such as youtube
have plenty of demonstrations and walk-throughs; you may even find some
specifically for your model, but the industry is a mass-market, and so
it tends to build products very similarly. Typically, you would need to
unscrew several ... screws, then use a blade to separate and pop the
panel surrounding the keyboard, and then carefully move and detach the
keyboard from the motherboard. At that point, you would typically be
looking at an aluminum panel that insulates the motherboard from the
keyboard rf. It should have a bunch of holes, each of which exposes a
connector on the motherboard. Each motherboard connector is typically
labeled pretty obviously (eg. mic, spkr, camera).

A more involved but still doable repair is to replace the internal
camera. Again, there are youtube videos. I did it once just for giggles,
without using any special tools, and I wouldn't hesitate to do it again.
Just be patient and follow the instructions.

If I were to do it again, I'd prefer to use the specialty separator tool
instead of using a thin blade, but the thin blade worked.

Re: Lenovo ideapad 710S-13IKB bios/boot issue

[Gabor Szabo]

In the end I created a USB with Ubuntu 20.04 and installed it in the empty
partition that was already set aside for Linux.
This configured grub so it now has a menu in which I can select either
Windows or Linux.
It also changed the BIOS so now I have a bootable entry for Windows as well
as for ubuntu.
The former gets me in Windows directly, the latter show the grub menu.

All that after changing the disk from RAID to AHCI in the BIOS.

Thank you all for your help!

Alone?


At work, we've had Asus laptops that we installed with Linux that
  started only agreeing to boot once every 4 to 100 tries. We've had
  a co-worker literally sit for one hour just trying to start his
  computer.


We returned one of them, and the store kept it for 10 months
  () until Asus released a BIOS upgrade that solved the problem.
  And then the store owner had the gall to try and bring us back the
  (almost brand new when it was returned) laptop.


All further laptops we bought were Dell.


  

  The BIOS does not even have an option to boot into
Windows any more.
  

  

That's a completely different problem. Something deleted the Windows
UEFI entry from the BIOS. I'm not sure how to restore it (probably
boot a Windows recovery disk).

Yes, that is strange, but of all problems you describe, probably the
least strange. I wouldn't start with this issue. If pushed, try to
see if secure boot is enabled. If Linux was originally installed
without placing signing keys in the BIOS (or those keys were deleted
by the upgrade), weird things are _expected_ to happen.

  

   
  

   
  What I don't understand is why your Windows would stop

UEFI boot sequence starts at the BIOS. Unlike the legacy sequence,
where the BIOS would unconditionally load the boot loader, and any
boot selection you want to do is done after the BIOS has finished,
UEFI needs the

I can't help with Windows, but your final question seems easy (or am I
mis-understanding?).

If you just want to access the hard drive, why not try sudo fdisk -l to
get info about the drive and then either mount the relevant partition
manually or add it to /etc/fstab on the USB drive?
