Can't boot from USB on Sony Vaio VPCEB11FM

I wanted to install Windows 10 on my 2010 Sony Vaio VPCEB11FM laptop. Sony’s support for this product is terrible and I could not find anything I am looking for.

The problem is, it won’t boot to the USB. I use Rufus, MBR, NTFS. I went to the BIOS (Aptio Setup Utility), there was no CSM, UEFI, Secure Boot option. Nothing, just Boot from External Devices (which is ON) and the Boot order. I changed it to USB, CD, HDD. When I reboot, I see the VAIO screen, it goes blank. It shows something like a command prompt, only I can’t do anything. There was just this blinking underline on the top right screen. No text at all.

Is this an error on the formatting? Do I try a new flash drive? A new ISO for Windows 10? This laptop has been reformatted 2 times. This was supposed to be a Windows 7 Home Premium 64-bit but the idiotic repairmen changed it to 32-bit. Now I can’t even install new OSes.

By the way, pressing the ASSIST button doesn’t do anything. It just boots like normal. Any fixes?

you can try pressing F11 during boot process to go directly to USB boot. I found this on a youtube video and I could not find this anywhere else on the internet. It really works. Hold or press many times the F11 button during the start of the boot process and Vaio will search first the USB trying to boot from there. To me worked on any USB port. Unfortanelly, I also can not boot yet from USB, but I guess it is an issue with my pendrive. I´m also looking for a complete answer and solution to this, so expect another edit on this answer, I hope soon. Good luck to us.

EDIT: I got another pen drive and then the F11 solution worked out straight away! hope this helps someone else too.

From the VPCEB11FM user manual:

Disconnect all other devices and ensure that the AC adapter is plugged in.

1 Connect an external device to your VAIO computer. Press the ASSIST button while your VAIO computer is off.

2 The VAIO Care (Rescue Mode) screen appears. Select Start from media (USB device/optical disc).

3 The booting process from the external device starts.
