Need help starting my laptop please?

How can I get my laptop to start again?

Apparently no operating system is installed. Have you recently swapped or removed any hard drives?

It says there: No bootable hard drive / SSD available

I removed a few apps from the laptop today and you can't restore it

Before he went

So it shouldn't have anything to do with apps

Earlier he went he had deleted something from the memory that can't be restored somehow

What did you remove

Unfortunately, I don't know a good question from a few apps

How can I restore it

Then… Probably died in a short time. Sometimes it goes from before to now

Go into the BIOS and see if there's a hard drive or SSD registered

How do I do that

So if you really haven't deleted anything on the operating system, your 2.5 "hard drive has a contact error, a kind of loose contact. But this would only be the case if you had recently removed the hard drive.

I think I deleted something on the operating system, I can restore it

Will be difficult because he can't find a "boot device" to start up.

Try to get into the boot menu and start the pc in safe mode. (If it works)

Next I would personally insert a windows installation cd and go to repair and if that doesn't work

→ Remove hard drive → Save data on another PC → Format hard drive and restart Windows

How do I get into the boot menu

It depends on which laptop you have, i.e. Which brand

for some it is f2, f3, f11 or fn + f2, but there can also be a button on the side (lenovo) that you have to press when the pc is off to access the bios and there you can change the boot order
