Why can't I install Ubuntu on Lenovo s205?

Question

linux

My netbook has UEFI, so I followed the guides and made the markup like this

/dev/sda1 150MB EFI
/dev/sda2 4GB swap
/dev/sda3 300GB ext4 /

As stated, I installed the boot installer in /dev/sda1. After installing Ubuntu, the OS does not start during startup and I only see the boot menu, where there are such items:

1. ATA HDD0: WDC WD3200BPVT-24JJ5TO
   
2. Windows Boot Manager (I don't know why)
   
3. PCI LAN: Realtek PXE B02 D00
   

If you click on any element, it loads a window with any text for a couple of seconds and from the main one it displays the inscription PXE-M0F: Exiting PXE ROM. I googled, so put the HDD in the first place, but this does not solve the problem. I used to have Ubuntu here, but now for some reason I can not install it in any way. How can I solve my problem?
