I need remote assistance to reinstall Windows via a call with screenshots and demonstration. When rebooting the system with the USB drive inserted and pressing F4 to switch to USB reading mode multiple times, the system did not open the USB drive and just loaded Windows. In cases where the USB did load, after selecting the region in the menu and pressing the next button, everything crashed and it still loaded the regular Windows. After that, the USB drive was selected as a priority in the boot menu in the BIOS. I managed to reach the version selection of Windows and start the installation. During the installation process, after 60%, an error occurred while installing Windows. I repeated the same steps from the beginning and the window appeared "It seems you have started an update and performed a boot from the installation media. If you want to continue the update, remove the media from your computer and click "Yes". If you want to perform a clean installation, click "No". After pressing the "No" button, the system reboots and this window appears again. At this point, the system is stuck in a loop. I don't want to go into the BIOS and dig around myself. I need someone who understands what they are doing and can help solve this problem. Please do not write to me if you plan to help using neural networks. I need a specialist, not a prompt maker.

Description: Greetings! I am looking for a specialist/integrator for fiscalization systems and platforms for an online store. I have opened an individual entrepreneur (IE), have a digital signature key and an IBAN account. There are no other accounts (in Checkbox, platform systems, CRM) yet — everything needs to be registered and set up from scratch, turnkey.
