I've got an older Vaio, model VGN-S550P. I'm trying to load it up with a new OS from USB, but I'm having no luck getting to to recognize the flash drive. It doesn't appear in the boot menu or BIOS, and there's not option for booting from USB therein.

If anyone has any suggestions I'd be most thankful.



  • Did you try F11,Esc or F10 at boot to get a boot menu? – Moab Apr 2 '19 at 20:49

The issue you are facing is a common one with older motherboards. Only until the last 5-7 years did motherboards allow you to install an operating system from USB. Just to be clear, this issue is a motherboard issue 100%.

According to Sony's Website. Your computer is around 10 years old. It's very doubtful your motherboard will allow such functionality. But without the exact model of the motherboard, it would be impossible to say. The fact that you mention it's not in the bios setting, should give your answer right there.

My guess is you probably assumed loading an operating system via usb was always "a thing". But USB flash drives are actually a very recent technology

Solution: You'll need to install the OS via CD/DVD rom.

Have you ensured the USB is a bootable drive? What tool did you use to create the USB?

I have used Rufus or Unetbootin with success in the past.
