I removed Windows Boot Manager option from BIOS (UEFI) with EasyUEFI, after reboot I got an error message about broken BCD, need to be recovered, I tried to reinstall Windows 8.1.1 Pro X64 from USB installation, which I prepared with Rufus, there I set GPT partition scheme for UEFI computer, but when I tried to boot from this USB and perform installation I get the message Operation System not found.
I played with boot settings in BIOS, tried all possible boot combinations: legacy, Secure Boot On/Off, BIOS/UEFI, but I still can't make my Windows USB Boot stick work.
The only I can do is to install Ubuntu/Xubuntu on my laptop, but I need Windows. I also tried to completely rebuild disk partitions during Xubuntu 14.04 installation and after that retry to install Windows, but it doesn't work too.
I paid attention, that before I deleted Windows Boot Manager I could add Windows 8.1.1 boot option from USB in BIOS/UEFI, but now there is no such option, it only let choose SATA and not USB.
How to install Windows after I removed Windows Boot Manager from the BIOS boot tab?
I'm using Dell Vostro 3460 laptop, with the latest system BIOS v.A19.
Thanks!

The problem was in that I formatted installation USB-stick into NTFS file system instead of FAT32. Now, when I rebuilt installation media with Rufus everything is working!
Thanks.
