Friends I have an HP Slate 21 S100.
I installed TWRP a few days ago.
Then I installed software with TWRP and my device was working without any problems.
Then I said to install another software again and the device crashed.
First, I could not enter TWRP, although I reinstalled.
Then it went to boot menu while experimenting with fastboot.
This is the screen when I enter the recovery menu.

This is the error she gave when she selected the Recovery Mode

Then it returns to this screen again.

I would be glad if you could help.

As I can see your phone stucks in Fastboot ( AKA Bootloader ) mode: in Android device's boot-mode is set by ro.bootmode property - what can be normal, recovery or fastboot - which is set in Android's system file named build.prop.

Simply flashing some images as you did doesn't cause this property gets reset.

Typically you reset device's boot-mode property by means of ADB and/or Fastboot commands

ADB
Code:
adb devices
adb reboot

Fastboot
Code:
fastboot devices
fastboot reboot

Telefonunuzun Fastboot (AKA Bootloader) modunda takıldığını görebildiğim gibi: Android cihazının önyükleme modu, Android'in build.prop adlı sistem dosyasında ayarlanan ro.bootmode özelliği tarafından ayarlanır - normal, kurtarma veya fastboot olabilir .

Yaptığınız gibi bazı görüntüleri basitçe yanıp sönmek, bu özelliğin sıfırlanmasına neden olmaz.

Genellikle aygıtın önyükleme modu özelliğini ADB ve / veya Fastboot komutları aracılığıyla sıfırlarsınız.

ADB
[kod]
adb cihazları
adb yeniden başlatma
[/ kod]

Fastboot
[kod]
fastboot cihazları
fastboot yeniden başlatma
[/ kod]
OEM lock is on.
I'm installing recovery.img in fastboot mode.
fastboot flash recovery recovery.img
then when I turn it off and on again it comes to the fast boot mode screen.
I tried all the recovery.img files.
but it didn't happen.
Fast Boot Mode screen
Start - restart booting failed
Power Of
Recovery Mode - restart booting failed
Restart bootloader - restart booting failed
Can you describe how to do it from the very beginning?

You managed to softbrick your phone hence you also should be able to unbrick it.
But this requires some knowledge: Your posts here show me that you have no understanding how things are working, which action triggers which consequences, what tools are the right ones to be used.

Anyways:

Because phone is accessible in Fastboot mode - as you said - simply re-flash phone's stock ROM to get rid off of all mods you applied to phone. This basically can be achieved by means of Fastboot tool:

Code:
fastboot devices
fastboot flash bootloader <BOOTLOADER-IMG-FILE>
fastboot reboot bootloader
ping -n 5 127.0.0.1 > nul
fastboot -w <STOCK-ROM-ZIP-FILE>
fastboot reboot


Take note that this as 1st thing of all things requires to have installed on computer the Android USB Driver provided by HP matching your HP Slate 21 S100: Request it from HP if you can't find the driver at your own.

Another possibility would be to take the phone to autorized service center and let them fix it.
