Error installing Windows?

Question

Windows

Hello.
Windows crashed on Lenovo. When I tried to install a new one, the laptop hung at the "start of installation." Then I couldn't enter BIOS. After that, I tracked the battery on the motherboard for a while. Then the "checking media" error began to appear, then the "Efi" error usb device boot failed.In BIOS, there are only two lines with "efi network 0 for ipv4 boot failed" ..and one menu with boot manager..After pressing enter, the error "No bootable device - Please restart system" appears..And that's all, more nothing can be done, and so on in a circle. Please tell me what can be done? How to fix these errors?

Answer 1

Bios can't find where to boot from. Is the hard drive visible in the bios? And I still do not understand what's wrong with the bios battery? She is alive?

Answer 2

First, change the battery
Second, look at how to enter the BIOS in your particular laptop model so that you can configure boot options, because the manufacturer specifically limits this.
And then it's very simple.
1) If you have UEFI - format the flash drive in FAT32 and boot via BOOT CMS
2) If you have a regular BIOS (UEFI CMS) - format the flash drive in NTFS and boot through the selection of a physical device in the BIOS.
