What to do if you can’t enter bios on a laptop?

Question

Domain Name System

In general, there is a DNS a15hc (0133836) laptop, I decided to put Win10 on it, it says Bootmgr not found when loading, okay. While I was thinking about it, I decided to format the hard drive, plugged in the USB flash drive, went into bios, set boot priority from the USB flash drive and eventually booted into linux and through GParted, after which I demolished all partitions (formatted everything clean in ntfs).
And now the problem - nothing starts at all! Already confused, how to be? Black screen and all. I tried to stick a hard drive from my beech (swap), it doesn’t work either, but now the system doesn’t start on my laptop either: D But that’s okay, I think I’ll fix it, because there is access to the BIOS (on my laptop) and the problem with the bootloader is more likely Total.
What happened to the DNS laptop when I formatted the hdd? When turned on, I tried to hold down Esc, f12, f2, Del: none of this helps. Perhaps the download goes through UEFI ... What should I do?)
Maybe what flags need to be changed?
Took out the battery.

Take the laptop to where you got it and say: "It's broken, it doesn't work. Give me another one or return the money!"
PS I do not know if this is the case, but: I was going to install Windu - and I had to format it from under Windows during installation, and not from under Linux.
